Fish Breed


The African glass catfish, Pareutropius Debauwi Fish is one of the Schilbeidae family, which consists of catfish. It is native to Africa, where it can be found in the Republic of Congo, Democratic Republic of Congo, Gabon and Central African Republic. It faces no serious threats to its survival.

Pareutropius debauwi was named and described by George Albert Boulenger in 1900. Their common name is African Striped Glass Catfish, and they belong to the Glass Catfish family (Schilbeidae). This family includes about 9 genera and 46 species.This fish is found in Africa, specifically the Congo River Basin, Lake Tanganyika and Lake Mal. The common names for this fish are African Striped Glass Catfish and Leopardshark.

The smallest fish in the family is called Pareutropius debauwi. It was named after Rene de Bauw, a Belgian author. The word “Pareutropius” means “beside keel” and refers to the compressed body of this species. The genus name Pareutropius is made up of three (ancient) Greek words: Par means beside or near, Eu means well and Tropis means keel; a reference to the compressed body of this species.

The African Glass Catfish has a range that covers four different countries. It occurs in the Congo River basin and many other rivers in this region.

Pareutropius Debauwi Physical Appearance

  • The African Glass Catfish has a silver color with a black stripe down the flank.
  • Pareutropius Debauwi also has a dark line above its anal fin on its stomach as well as 4 beards on its snout.
  • They can reach a total length of 15 centimeters.
  • The difference between the sexes of a species is difficult to see.
  • Adult females are larger and bulkier than the males.
  • The difference is noticeable in a group of adults, but not in a single animal.
  • This can be seen more easily in young specimens than in adulthood.

Pareutropius with its physical Appearance

The African glass catfish has a long anal fin that is deeply forked. Its eyes are large while its mouth is small. The fins are transparent and it reaches about 10.4 cm long. It travels in schools and is found in Africa, Asia, Australia, Central America, Cuba, Europe, New Zealand and North America.

Pareutropius debauwi and Pareutropius buffei are often confused. The key difference between the two is that the buffei has a third black stripe along its side and dots on its caudal fin tips. However, P. debauwi has pointed edges to its caudal fin, while those of The tips of the caudal fin of  P. buffei are rounded.

Pareutropius Debauwi Habitat

Provide this fish with a spacious area that is long and contains densely planted areas, bogwood, rock around the edge, and some open swimming space toward the center. They do not like bright lighting so floating plants are desirable.

Aquarium can be provided for this fish with enough space for swimming and hiding. A long tank is best, as well as dense planting of bogwood and rock around the edges of the tank.

Pareutropius in its habitat

Carnivorous, bottom dwelling fish. The African upside-down catfish is a native of the Congo River Basin in Africa. It enjoys a temperature range of 77 to 86 degrees Fahrenheit and prefers water with good current flow and good amounts of vegetation. This fish may nibble plants if not fed sufficient amounts of food. This fish’s caudal fin is constantly moving, when resting or swimming. This fish may get caught in a net because of spines on the dorsal and pectoral fins.

Pareutropius Debauwi Feeding

Pareutropius debauwi are omnivores. They will eat both meaty foods and plant material, so you should give them a good mix of flakes, granules, frozen food, live daphnia or brine shrimp. Make sure that the diet also contains some vegetable matter.

Pareutropius Debauwi Breeding

The Pareutropius debauwi are egg scatterers who release their eggs between the plants. If you have some mash through which the eggs can fall but that the parents cannot get through, this certainly helps to protect the eggs. The eggs are usually deposited between the leaves by morning.

New breeding of Pareutropius debauwi species

The male immediately fertilizes the eggs. A single spawn can contain up to 100 eggs. The color of the eggs is whitish. The lifespan of Pareutropius is short. With proper care, they can live up to 5-8 years.

The West African lungfish has the widest distribution of any species in the family, found across large stretches of western and central Africa. It is also found in northern portions of southern Africa, where it inhabits a variety of freshwater habitats including rivers, streams, ponds, swamps and other waterlogged environments.

The African lungfish certainly lives up to its name. These fish have barely changed over the last 400 million years, and are sometimes called “living fossils.” It lives in rivers and other waterways in Africa. The secret to its longevity is its adaptations—it has two lungs like we do, which means it can breathe air if necessary.  this species is able to survive in water or out.

The West African lungfish is found throughout Africa, specifically in the basins of Sahel as well as Guinea and Sierra Leone. This subspecies of the lungfish has two different subspecies; P. a. annectens is found primarily in the basins of Sahel, while the other subspecies, P. a. brieni is known.

A lungfish’s hibernation also includes a behavioral adaptation. A behavioral adaptation is a way an organism acts. Prior to hibernation, lungfish frantically burrow into the muddy ground as a means of protection. Their behavior as they dig allows them to create a safe place where they can survive over the long period of dormancy.

The African lungfish lives in the Mbali River of the Republic of South Africa. It has a five-chambered heart, which is an adaptation to its low-oxygen habitat. It also has three sets of gill arches on each side, instead of two as in most fish.

Lungfish do have gills, but they also have true lungs that enable them to breathe through their mouth. The lungfish must be able to access air in order to breathe, or else it will drown.

African Lungfish Physical Appearance

  • The African lungfish has a prominent snout and small eyes.
  • Its body is long and eel-like. It has two pairs of long, filamentous fins.
  • The pectoral fins have a basal fringe and are long, while its pelvic fins are about twice the head length.
  • In general, three external gills are inserted posterior to to the gill slits and above the pectoral fins.

African lungfish are long, slender fish with eel-like bodies. They have “fins” at their backs that allow them to propel themselves forward, as well as alternating “steps” that enable them to move in a hopping motion.

African lungfish with physical appearance

African lungfish have a long, dark-colored body that’s covered with black or brown spots. They have a lighter colored dorsal side. An African lungfish can reach up to 39 inches in length and weigh 10 pounds or less. They can live for  20years.

African Lungfish Habitat

African lungfish are obligate air breathers, meaning they must always have access to the surface for air. They are freshwater fish that live in riverbeds of Africa. During dry seasons, the water levels can become so low that African lungfish burrow into the sand and can hibernate for up to a year. Most African lungfish only aestivate. African lungfish can aestivate for up to a year.

lungfish dig deep into the mud, forming a safe and comfortable home. When ready to sleep, it wriggles around and creates a tunnel for air. During this state of suspended animation, lungfish take in no food or water and make no urine or waste.

African lungfish in its habitat

lungfish can tolerate water with little oxygen and will burrow themselves into mud for protection or to escape predators. They can do this because they have a unique ability to breathe air, which allows them to survive under low levels of oxygen.

African Lungfish Feeding

African lungfish are a part of the Class Sarcopterygii, the subclass Dipnoi, and order Ceratodontiformes. Lungfish species can range in size from 1 to 3 ft (0.3 M). They hunt for frogs, fish, mollusks, tree roots and seeds. The African lungfish can survive up to 3.5 years without eating.

African Lungfish Breeding

The lungfish is found in Africa and southern Asia. They are freshwater fish that live in burrows in the mud, with only their heads sticking out to breathe. Females lay their eggs in a nest they dig in areas of vegetation near water. Once the eggs hatch after about two weeks, the male guards them for up to two months until they can survive on their own.

The alewife fish breed, Alosa pseudoharengus, is a species of anadromous fish native to the northern Atlantic coast of North America, living most of its life in the sea but swimming upriver to spawn. Alewives are a type of herring and belong to the family Clupeidae.

The species was first reported from Lake Erie in 1931, Lake Huron in 1933, Lake Michigan in 1949, and Lake Superior in 1954. The spread of Alewives in the upper Great Lakes is thought to be enabled by warmer weather in the 1950’s

In some populations of alewife, the fish live entirely in fresh water. The alewife is most famous for its invasion of the Great Lakes by using the Welland Canal to bypass Niagara Falls. In the lakes, their population surged, peaking between the 1950s and 1980s to detriment of many native species of fish. To control them biologically, Pacific salmon were introduced.

In the Great Lakes, alewife became abundant mostly in Lake Huron and Lake Michigan. They reached their peak abundance from the 1950s through the 1980s. In order to survive, alewife required a food chain with no top predator. As a result of the lack of predators, they grew in number unchecked.

In the spring, adult alewifes move upstream to spawn. Fisherman catch them using dip nets in shallow areas of the river. They are used as bait for lobster traps during Maine’s spring lobster fishery.

Alewife fish breed

The fish has seen a decline in its population throughout much of its range, due to several threats. One major threat is the construction of dams and other impediments to migration. Dams have prevented alewives from migrating upriver to spawn, so their populations have declined. Other threats include habitat degradation, fishing, and an increase in predation by recovering striped bass populations.

Alewife Fish Physical Appearance

  • The Alewife Fish, Alosa pseudoharengus, is a small herring that is comparable in size to the American shad.
  • Alewives are often mistaken for river herring because they have similar characteristics.
  • The head of an alewife is broader than it is long, and its eyes are large with adipose eyelids (Wormuth & Wisner) fish with a dark upper side, bluish to greenish, and light sides with horizontal darker stripes. A dull black spot is located behind the operculum. Scales are easily rubbed off and form scutes on the mid.

Alewife with good physical appearance

Alewife have inconspicuous jaw teeth and no tongue teeth. The caudal fin is forked, with no adipose fin. They are visually similar to Blueback Herring, but Alewife has a peritoneal lining that is white, larger eyes, and a greater body depth than Blueback Herring. The freshwater gar grows up to 38 cm, but inland populations are usually less than 25 cm.

Alewife Fish Habitat

Alewife Fish are anadromous, living in salt and brackish marine areas as adults and returning to freshwater to spawn. Alewife can spend their entire life in freshwater, prefer marine environments where they can feed on smaller organisms, but they are able to survive in freshwater. They spawn in the spring, and then return to the sea.

Alewife playing in its habitat

Alewife Fish Feeding

The diet of the Alewife Fish is diverse, as it feeds on zooplankton. It also selects for the largest zooplankton in invaded water bodies and subsequently has altered the species composition of zooplankton in the Great Lakes where Alewife are abundant.

Economic Importance of the Alewife Fish

As a result of the alewife’s migration patterns, it was able to thrive in the upper lakes between 1931 and 1954. It faced little competition or predation during this time and became the most abundant species. Alewives are not of commercial value, however; their presence has caused costly sanitary operations when, periodically, millions of them die and wash up on  shorelines. It is a good fish.

Small Scale Catfish Farming Business is a good business idea that can be implemented and profited from. Catfish farming is popular because of the top standard of protein it produces and its function in increasing vitamin consumption. Because of the enormous demand for and consumption of fish, the business can be quite successful if well managed. Catfish farming is one of the fastest-growing segments of the animal feeding industry.

Before you start Small Scale Catfish Farming Business, keep in mind that the industry is vast, and like any other business, you must be willing to take risks. Catfish farming is separated into various specializations, which are further broken into enterprises. Catfish farming entails more than just buying fingerlings, putting them in a tank, and feeding them until they reach marketable size.

Starting a Small Scale Catfish Farming Business involves labor, devotion, and, most significantly, passion, and an entrepreneur’s interests will determine the business’s mission and vision. To begin successfully producing catfish, one must examine the size of the farm, the size of the production, capital, the anticipated quantity of stock, location, pond, market, fish species, water availability, and legal difficulties.

Catfish farming business: using water tank as pond

There are some prerequisites for starting a catfish farm, which vary depending on the scale of the aim based on capital. When you have this expertise, starting and running a fish farm is not as tough as it appears. The size and vision of the entrepreneur play a role in the success of a farm.

Catfish Farming Business can take place on a small, medium, or big scale. A small-scale institution can hold a maximum of 50,000 pieces of startup sizes, a medium-scale establishment can hold between 50,000 and 100,000 pieces, and anything over that is a big-scale establishment. Small Scale Catfish Farming Business Plan; Fish farms are simple to maintain as long as the fish are fed high-quality feed and the ponds are secure. The farmer can expect a healthy yield.

Setting up a fish farm necessitates more meticulous planning and substantial financial investment. Depending on the pond type and the number of fish to rear, it can cost between N100,000 and N500,000 to meet all of the fundamental needs for starting a Small Scale Catfish Farming Business Plan

What to Consider when starting a Small Scale Catfish Farming Business Plan

  • Getting a pond
  • Location
  • Feeding
  • Management of the pond

Small Scale Catfish Farming Business Plan

Getting a pond

A pond is required for the fish’s rearing, this is the first step to factor into in Small Scale Catfish Farming Business Plan. Plastic ponds, tarpaulin ponds, concrete ponds, and earthen ponds are the most prevalent and simple to manage forms in Nigeria. When choosing a pond system, an individual who is unfamiliar with the system may need to seek expert help, as there are additional things to consider based on the focused phase of production.

Any of them has benefits and drawbacks, and your decision may be influenced by the number of fingerlings you wish to raise. It is not difficult to set up the ponds, but one must ensure that there is a sufficient drainage system in place; this is where the sewage work must be completed and monitored.


The safety of the area should be considered when selecting a catfish breeding spot, that is to say; location is important factor when going into Small Scale Catfish Farming Business Plan. However, as is customary, make sure it’s in a location that’s close to raw material availability as well as your consumers. You should also think about whether or not the place is conveniently accessible to everyone and whether or not it is motorable.


Starting with fingerlings, which are usually four weeks old, will take up to fourteen weeks of daily feeding to get them to smoking size. Whereas post-fingerlings are usually six weeks old, they can take up to thirteen weeks of daily feeding to reach smoking size. When their fish reach six weeks, some people prefer to feed them local feed which is considered in Small Scale Catfish Farming Business Plan.

Maggot and hatchery waste are used in the local food. Before feeding the fish, the hatchery waste must be cooked. This method is employed in the fish farming industry to reduce costs. In this business, one thing to keep in mind is to keep your mortality rate as low as possible.

Catfish farming business:

You must be able to properly control fish feeding in order to run a productive fish farm. Catfish eat twice a day, in the morning and evening, and the water would need to be changed frequently (every two days on average) since feeding causes excretion, and it is dangerous for catfish to live in stagnant water.

Management of the Pond

A high mortality rate has been highlighted as one of the reasons why many farmers lose money in this industry. You should keep an eye on your fish’s health, and the pond should be safe from predators. To prevent infections from spreading across the pond, scouting should be done on a daily basis and questionable fish should be segregated from the pond for Small Scale Catfish Farming Business Plan.

The yellow boxfish (Ostracion cubicum) belongs to the boxfish family. The Ostraciidae family contains 23 different fish species. It can be found in the Pacific and Indian Oceans, as well as the southeastern Atlantic Ocean, on reefs. A yellow boxfish’s scientific name is Ostracion cubicus. Ostracion is a Latin word that refers to the carapace or shell structure of this fish. Cubicus translates to “cube-like.”

Although it is extremely unusual, when a boxfish is stressed, it can release a lethal poison known as “ostracitoxin,” which can cause it to kill itself and everyone else in the waterway. If it dies, this can also happen. When anything is about to die, it becomes slower and the colors fade more quickly. You can detect whether there is poison in the water by seeing foam on the surface and other fish that are dormant. The brilliant yellow tint and black patches are a type of aposematism (warning coloration) to any possible predators.

Yellow boxfish species in its habitat

Distribution and Ecology of Yellow boxfish

The Pacific, Indian, and southeastern Atlantic Oceans are home to these saltwater fish. They can be found off Australia’s western and eastern beaches. Yellow Boxfish can also be found off the coast of the United States. They live in lagoons and have a coral reef habitat. These fish can be found in depths ranging from three to 920 feet. They are saltwater fish that require water temperatures of 72 to 78 degrees F. They also require a pH level of 8.1 to 8.4 in the water. They are popular because of their horned, colorful, or otherwise distinctive appearance.

Different Types of Yellow Boxfish Species

Smooth trunkfish: The shape and texture of this fish’s body earned it the name. It’s dark brown with white flecks. They can be found in the Atlantic Ocean off the coasts of Mexico, Florida, and South America’s eastern coast.

Yellow boxfish species

Round belly cowfish: It gets its name from the two little horned structures that protrude from its head. They can be found on coral reefs in the southeastern Atlantic Ocean and in the Pacific Ocean off the coast of California.

Spotted boxfish: These fish live off the coast of Mexico in the Pacific Ocean. The white-spotted boxfish is another name for them. Their elaborate, vivid blue bottom body with golden spots explains this.

Body Characteristics

As a boxfish gets older, its look changes. It’s box-shaped, as the name implies. Boxfish are also noted for their armored and inflexible bodies, which impede mobility in most circumstances. The boxfish’s carapace shape, which is far more advantageous for its modified way of swimming, known as ostraciiform locomotion, compensates for this disadvantage. It is a bright yellow color when young.

The coloring fades with age, and very old examples have a blue-grey to black coloration with faded yellow. Yellow boxfish can grow up to 45 centimeters in length (18 in). The shell structure beneath their scales gives them a boxy form. Because of their unusual form, they are slow swimmers. Some even characterize their motion as floating.


The diet of the yellow boxfish consists primarily of marine algae, but it may also consume worms, sponges, crabs, mollusks, and small fish. A boxfish will occasionally blow water into the sand in search of flora and food. They hunt for tiny prey across rocky slopes and at the sandy bottom of a lagoon.


Yellow boxfish species sucking the diets

The yellow boxfish is a solitary creature. Breeding takes place in tiny groups of 1 male and 2–4 females in the spring. Females lay eggs towards the surface of the water. The male boxfish releases sperm to fertilize the eggs. A female boxfish can lay eggs every day for a month. The length of the pregnancy is unknown. On average, boxfish live for four years.

Fish farming in Nigeria is one of the most profitable agribusinesses in Nigeria, and as such, investing in agribusiness is a wise move, especially given the strong local demand and export possibilities. Actual Manufacturing Procedures The fish cycle begins with the delivery of fingerlings from the market to the pond, followed by feeding them various diets until they are ready to be harvested and sold at the market.

Fish Farming In Nigeria- Fish farming is a company that anyone can invest in. It can be very profitable if you know what you’re doing, or it can be a loss-making endeavor if you don’t. Many people who engage in fish farming in Nigeria do so for financial gain. Catfish farming is practiced by about 80% of Nigerian fish farmers. Catfish is the most prevalent fish utilized in Nigerian aquaculture. Fish farming is possible in all Nigerian cities, towns, and villages. This business can be conducted everywhere in Nigeria.

Fish Farming In Nigeria- with farmer inside the pond

The quality of fingerlings and other fish seeds, the quality of water, the PH of the water, dissolved oxygen in the water, ammonia, cleanliness of the farm, and turbidity are all elements that contribute to fish farming failure in Nigeria. Fish farming has the advantage of not being seasonal like other types of farming. It can be done both in the rainy and dry seasons.

Fish has been widely farmed in both the southern and northern parts of Nigeria by fish farmers. Around 1950, the first domestication of fish took place in Nigeria. Catfish can be found in Nigeria’s freshwater bodies. Aquaculture is an industry that began over a century ago in Nigeria. In Nigeria, people have always farmed fish, particularly catfish, for decades.

In the 1950s, spawning, breeding, fish farm management, harvesting, and marketing were all part of the catfish domestication attempts in Nigeria. Before some of them switched to aquaculture, fishermen in Nigeria utilized boats, nets, and hooks to collect fish in rivers and other freshwater bodies.

Habitat for Fish Farming in Nigeria

Fish Farming In Nigeria- Fish is found throughout Nigeria. It can be found practically everywhere in Nigeria in its natural habitat. Rivers, floodplains, lakes, streams, and wetlands are all home to fish. They can travel from larger bodies of water to flooded areas to reproduce and then return to their original habitat. fish migrate in uncultured water primarily for the purpose of reproduction. fish are raised in tarpaulin-lined pits, earthen ponds, concrete ponds, plastic tanks, and fiberglass, among other places in Nigeria.

Fingerlings are usually purchased from established catfish farms, but they can also be found in Nigeria’s flooded plains near rivers and dams. Following the introduction of fingerlings to the farms, fingerlings are fed grains and soya meals on a regular basis.

Fish Farming In Nigeria- with a farmer turning the net

Fish Farming In Nigeria-Large hatcheries managed by professional fish growers in Nigeria have intense recirculation systems. These hatcheries use genetically enhanced broodstock and live creatures as feed. The success rate of eggs to fry in these hatcheries is around 70%, with some hatcheries reporting success rates of over 80%. The demand for fish fingerlings in Nigeria is enormous. It significantly outnumbers the available supply.

In Nigeria, earthen ponds are commonly used to raise fish. This form of fish farming entails excavating a specific amount of land and converting it into a pond where fish may be stocked, fed, and harvested when they reach maturity. Most fish farmers in Nigeria choose to raise their fish in ponds.

Tanks are frequently used in Nigeria’s urban regions. Unlike ponds, using tanks to cultivate fish does not necessitate any specific expertise or technicians. Fish tanks can be purchased on the open market and set up in a matter of hours. The tank might be made of plastic, steel, or concrete.

Challenges of Fish farming in Nigeria

The following are some of the problems and risks of fish farming in Nigeria:

  • Fingerling Quality: Poor quality fingerlings could perish or fail to grow, resulting in a loss of investment.
  • Fish farming requires significantly more capital than poultry or snail farming. Setting up a fish farm necessitates more meticulous planning and substantial financial investment.
  • Failure of the water supply: A break in the water supply is potentially dangerous to the fish, and if it happens, the fish have a high chance of dying.
  • Fish Loss: This loss could be due to sickness harming your pond’s fingerlings. Enteric Septicemia, Columnaris, Aeromonas, Virions, Tape Worms, Round Worms, Flukes, and other disorders are among them.
  • Fish are extremely difficult to handle, and even the tiniest oversight can result in degenerative growth or even death, resulting in significant revenue loss.
  • Contamination of the water: Spillage into the ponds could cut off oxygen access to the fingerlings or fish, killing them.

Management of Fish Farming in Nigeria

Fish Farming In Nigeria- with a farmer standing by the pond

Fish Farming In Nigeria- Fish producers should make every effort to follow all applicable laws and regulations in the country and region in which they operate. Fish producers in various Nigerian states must obtain governmental permissions in order to practice fish farming in certain locations. Small-scale fish producers are exempt from these permits.

Big Fish producers may need to apply for these permissions to be safe and avoid doing anything that is unlawful in the area where they operate. Water bodies should not be polluted by effluents that can harm residents, plants, and animals who use the water. Fish farm waste should be appropriately disposed of.

The Bluntnose Minnow Fish (Pimephales notatus) is a temperate freshwater fish that belongs to the cyprinid family’s Pimephales genus. Only the Nearctic area is home to the bluntnose minnow. They can be found from southern Quebec and Manitoba all the way down to Louisiana, and west to the Mississippi River watershed.

Its native geographic range stretches from the Great Lakes to Louisiana, south along the Mississippi River basin, and east across the Midwest to New York State. The bluntnose is a highly common freshwater fish in the Eastern United States, and it may be the most frequent.

Bluntnose minnow at its habitat

This fish is fairly frequent. In reality, in the eastern United States, bluntnose minnows are the most prevalent freshwater fish. In the fishing industry, bluntnose minnows are widely used as bait. They’re also employed as a source of nourishment for larger sports fish like bass. Bluntnose minnows play a crucial function in the ecosystem as prey for larger animals and predators on insect larvae.

Body Characteristics

  1. The term bluntnose relates to the flathead and snout of this species. They have a rounded head and a terminal mouth, though the snout hangs over the mouth a little. The dark coloring on the scales’ edges gives the body a cross-hatched appearance. These fish have cycloid scales, which are a type of leptoid scale. The rings on the scales can be used to determine a fish’s age.
  2. A bluntnose minnow’s lateral line runs from its head to its tail, ending in a black patch that distinguishes it from a fathead minnow. The scales between the skull and the dorsal fin are smaller than the scales on the rest of the body. The average length of a Bluntnose Minnow is 6.5 cm, with a maximum length of 11 cm. Males get darker during the breeding season, with a silver strip behind the gill cover (opercle) and 16 bumps in three rows on their heads.
  3. The Bluntnose Minnow Fish is a little silver fish with a dark stripe running from the snout to the tail. The stripe becomes a dot at the tail’s bottom. The upper parts are slightly olive in color, while the sides are bluish in color.


From southern Quebec to southern Manitoba, Canada, to Louisiana, United States, the bluntnose minnow can be found in the Hudson Bay and Mississippi River basins. They can also be found on the east coast of the United States, from the Saint Lawrence River in Quebec to the Roanoke River.

Non-indigenous populations have also been discovered in Connecticut, Georgia, Maryland, Massachusetts, New York, Ohio, South Dakota, Utah, Virginia, West Virginia, and Michigan, which are assumed to have been introduced through bait bucket releases or stock contamination.

Bluntnose minnow moving together in school


A freshwater fish, the bluntnose minnow spends its entire existence in the water. Bluntnose minnows enjoy small to medium-sized streams and creeks that are clear and stony. They can also be found in both natural and man-made bodies of water.

Bluntnose minnows enjoy shallow, clear water with a sandy bottom and can be found in lakes, rivers, ponds, and streams. They can be found in a variety of environments, including headwater bogs, swamps, and springs, as well as rivers, ponds, and lakes. In a single moderate-sized stream, up to a dozen species of minnows can be found. Swimming in huge groups or alone, they can be found.


Bluntnose minnows spawn anywhere from early spring to late summer, depending on their environment. They lay their eggs in depressions dug by them under stones.   Males’ heads will darken and their bodies will turn bluish during mating season. On their skulls, they acquire three rows of tubercles.

In eight to fourteen days, the eggs will hatch. Males’ physical appearance changes throughout the breeding season. When engaging aggressively with other men, they create a range of pulsing sounds. It’s unclear whether these sounds are used in courtship or spawning.


Algae, aquatic insect larvae, diatoms, and small crustaceans known as entomostracans are all eaten by bluntnose minnows. They will occasionally eat fish eggs or tiny fish. The maximum age of a bluntnose minnow has been documented at five years.



Blenny Fish Breed – Blenny, any of the many and varied fishes of the Blennioidei suborder (order Perciformes). Blennies are small marine fish that can be found in tropical and cold waters. About six families are known as true blennies, and they are grouped under the order Blenniiformes, with blenniiformids as their members.

Within the order, there are approximately 151 genera and nearly 900 species. Blenny refers to a variety of fish species, including several families of percomorph marine, brackish, and freshwater fish with similar morphology and behavior. The blenniiformids look a lot like members of the goby and dragonet families, as well as a few other unrelated families whose members have been given the nickname “blenny” on occasion. Many blennies imitate the behavior of other animals. This mimicry allows the blenny to approach other fish up close.

True blennies are commonly found in coastal waters, where they are often abundant and easy to observe, making them the subject of numerous ecological and behavioral studies. The splitting of the Tethys Sea caused by the formation of the Isthmus of Panama, as well as Pliocene climate warming, are thought to have influenced the emergence and biodiversity of the Blenniiformes. The Blennidae and Tripterygiidae have global distributions, the Clinidae has a temperate distribution, and the remaining three families are predominantly Neotropical.

Body Description

  • Blenniformids are small fish that have elongated bodies, some of which are almost eel-like, and large eyes and mouths.
  • Blenniiformids have elaborate whisker-like structures called cirri on their blunt heads.
  • Their dorsal fins are frequently continuous and long; the pelvic fins, which are located before the pectoral fins, usually have a single embedded spine and are short and slender.
  • The tail fin is rounded and the fish can grow up to 55 cm in length. Blennies, unlike other common reef species, can have a dark or bright color pattern.

Depending on the species of blenny, they may be uniformly colored or mottled to blend in with their surroundings. Males and females of some blenny species are color dimorphic, with males being darker than females. However, many species lack obvious external cues. Female blennies are occasionally larger than males. They are, however, united by characteristics such as a long dorsal fin and, if present, pelvic fins that are located near the throat and comprise one spine and two to four rays.

Venomous blenny species belong to the genus Meiacanthus. They have poisonous fangs that they use to defend themselves. Blennies are semi-aggressive fish that get along with a lot of other semi-aggressive community reef fish. They are not coral predators, but they will hunt small plankton on algae and live rock surfaces. Blennies prefer to have their own territory, so they don’t get along well with small, similar-minded species.


Blenniiformids are benthic fish that spend much of their time on or near the seafloor; many are solitary and may burrow in sandy substrates or live in crevices in reefs, riverbeds, or even empty mollusk shells. Some blennies also called rock-hoppers, jump out from water onto rocks to get to other pools. Blennies rely on a secretive style of living when it comes to predation, hiding on the seafloors in shallow water and having cryptic coloration.

Despite the fact that many species are detritivorous, that is, they eat dead plant and animal matter, some are primarily herbivorous, while others are partial to completely carnivorous. Bottom-dwelling fishes are known as blennies.


One or more female blennies may be courted by a single male blenny. The male may tend to the eggs once the females have laid them in a communal nest. Within seven to ten days, the larvae hatch. Harems can form, with one male reproducing with several females.

The black triggerfish, also known as the black durgon (Melichthys niger), is a blimp-shaped triggerfish with vivid white lines running down its dorsal and anal fins. One of the least threatening Triggerfish is the interesting Black Triggerfish. The Black Triggerfish is circumtropical, which means it may be found in oceans all around the world at similar tropical latitudes.

Black triggerfish breed in its habitat

Off the coasts of Hawaii and Polynesia, as well as the East Indies and the Indian Ocean, it can be found. Each Black Triggerfish has its own home amid the coral and rock formations just beyond the reef in the wild, but they will emerge and assemble in big schools near the top of the water to feed on current moving zooplankton and algae.

Distribution and Habitat

  • The black triggerfish can also be found along Africa’s southern coast.
  • The black triggerfish can be found in the Indo-Pacific and Red Seas.
  • Circumtropical. From Hawaii, across Polynesia, and over the Indian Ocean to the East Indies.
  • This species can be found in open waters, shallows, and exposed reefs in depths ranging from 5 to 35 meters.
  • They appear to prefer inland/coastal areas in the Ascension Island region, where they are unusually abundant.

Body Structure

It looks to be completely dark from afar. However, with proper illumination, it can be seen that it is clearly mottled dark-blue/green color, with orange toward the front of the head. Black triggerfish can change color in response to their surroundings. There are faint, light blue-turquoise colored lines on the face and around the eyes. There are prominent white lines running down the base of both the soft dorsal and anal fins. In the natural, the body seems to be black, but once out of the water and exposed to light, you can notice that the body is a dark blue to blue-green color with horizontal markings.

This species, like all Triggerfish, has a hard spiky dorsal fin that is carried flat against the fish’s body in a particular slot but may be locked into place if necessary. The Triggerfish uses its spine to keep itself in place when sleeping, making it difficult for predators to drag them out of hiding. The spine can also be utilized to ward off predators and as a weapon. It grows to a length of 12 inches on average but can reach up to 18 inches.

The interesting Black Triggerfish is one of the most peaceful Triggerfish and is relatively easy to keep. These clever fish can not only learn to eat from your hand, but they can also communicate in a variety of ways. The sounds or growls made by Black Triggerfish are intensified by their swim bladder. The Black Triggerfish is a very active fish that requires a lot of space to move around and a lot of hiding places. In fact, if this species is placed in a smaller space, it is far more likely to be hostile. The male and female Black Triggerfish have no discernible sexual distinctions.


Black Triggerfish find mates, lay eggs, and fertilize them. The eggs are then attached to a nest dug into the seafloor until they are ready to hatch. They will hide their eggs with broken shells if the substrate is too hard. Both men and females guard the eggs, however, females do a better job of it; both males and females are aggressive when guarding their nest.

As opportunistic omnivores, Small fish and squid are their main sources of food. Shrimp, zooplankton, algae, and other marine plant life, as well as marine algae and vitamin-rich herbivore diets, are all good sources of vitamin D. Triggerfish can even be taught to eat from your palm at the tank’s surface.
