What fish eat mosquito larvae, how to raise mosquito eating fish

Mosquito-eating fish. Mosquito-eating fish are mainly animal feeders. It has no edible value, but it eats mosquito larvae, which is beneficial to environmental protection and has ornamental value. Originated in North America, introduced into China, distributed in many provinces and regions south of the Yangtze River. It has also been colonized in many countries and regions around the world.

Its body is elongated, slightly flattened, the dorsal margin is shallow arcuate, and the abdomen is rounded and convex. The head is short and broad, and the snout is short. Big eyes. The mouth is small, superior, and the jaw teeth are small. The body is rounded and scaly, without lateral lines. The dorsal fin is located behind the midpoint of the body. The anal fin is located anteriorly below the dorsal fin.

The 3rd to 5th rays of the anal fin of males are lengthened to become a vas deferen. The caudal fin is rounded. The back of the body is grayish-black, and the abdomen is white. There are 1 dark spot on the dorsal head with black stripes along the dorsal part and the end of the caudal peduncle. Small fish for tropical freshwater life, ovoviviparous.

Multiple litters a year.

The medaka fish are all eaten, and the carp is a little bigger, and it is not too interested in the larvae of mosquitoes.

The most common fish in the medaka family are medaka and mosquito-eating fish.

How to raise mosquito-eating fish:

1. Feeding space, suitable fish tanks should be prepared for them, the breeding density should not be too large, and the large and small fish should be raised separately;

2. Water temperature, the water temperature is controlled between 18 and 30 degrees, which is the most suitable temperature for their growth;

3. Change the water, it is not recommended to change the water frequently, change the water once every three to four days. 2. Mosquito-eating fish can grow up to 5 cm, and females are longer than males.

Habits of mosquito-eating fish

Mosquito-eating fish swim in swarms on the surface of the water and are agile and agile. Feed on aquatic invertebrates, juveniles eat rotifers, ciliates, adults feed on insects, cladopods, copepods, chlorella, especially like mosquito-eating larvae, an adult swallows more than 2,000 a day.

Because mosquito-eating fish have no stomach and a stubby digestive tract, they are extremely voracious when preying on mosquito larvae. When the water temperature is suitable, each fish can swallow 40 100 mosquito larvae in a day and night, and can swallow more than 200 mosquitoes at most.

Mosquito-eating fish are small fish, not large, the female is only about 4 cm, and the male is more than 2 cm. It is similar to the guppy breeding method, and it is very easy to farm. Mosquito-eating fish in the wild feed mainly on rotifers and insects.

When the fish eats to the big belly, you should pay attention to separating them, it is born directly in the water and not laying eggs, the small fish born should be separated from the big fish, the big fish will eat the small fish, this kind of fish is very easy to raise, you don't need to change the water every day, you can change it once every three or four days.

Mosquito-eating fish pregnant females (with large bellies, you can tell at once) must be isolated in order to reproduce efficiently. Otherwise, it is likely that there will be no one left to eat.

The feeding feed of mosquito-eating fish is numbered as flake feed.

Raising mosquito-eating fish outdoors may result in a large number of fish dying if the temperature is too low. (Many mosquito-eating fish on the Internet are raised in warm water, and the temperature adaptability of these mosquito-eating fish is not good.) If the temperature changes too much, there will be a large number of deaths).

Mosquito-eating fish will attack other small fish if they reach a colony.

In the tank of existing mosquito-eating fish, new mosquito-eating fish are added, and the new incoming mosquito-eating fish will be regarded as an invasion by the "aborigines" and will launch an attack.

The little female fish caught in the field is ready to give birth again, and these two little have to make room again, and I don't know how many surprises they can bring this time.

Mosquito-eating fish eat mosquito larvae and are fishes of the genus Medakaidae. Mosquito-eating fish are small fish with warm temperatures, living in reservoirs, lakes, dams, swamps, rice fields, canals, depressions and other still water bodies. Swim in groups on the surface of the water and move with vigour and agility.

Feed on aquatic invertebrates, juveniles eat rotifers, ciliates, adult fish feed on insects, cladopods, copepods, chlorella, especially like mosquito-eating larvae, an adult fish can devour more than 2,000 per day.

Morphological characteristics: dorsal fin -5 6;Anal fin -6 7. Tandem scales 29 34.

Gill raker 12-15. Vertebrae 26-35. Body length mm:

The body length is times the height of the body and the length of the head. The length of the head is twice the length of the snout and the diameter of the eye. The body is elongated, slightly flattened, the dorsal margin is shallow arcuate, and the abdomen is rounded and convex.

The head is short and broad, and the snout is short. Big eyes. The mouth is small, superior, and the jaw teeth are small.

The body is rounded and scaly, without lateral lines. The dorsal fin is located behind the midpoint of the body. The anal fin is located anteriorly below the dorsal fin.

The 3rd to 5th rays of the anal fin of males are lengthened to become a vas deferen. The caudal fin is rounded. The back of the body is grayish-black, and the abdomen is white.

There are 1 dark spot on the dorsal head with black stripes along the dorsal part and the end of the caudal peduncle. Except for the pelvic fins, the rest of the fins have small black spots.

1. Guppies.

It eats mosquito larvae. However, the larvae of mosquitoes are relatively large and need to be cut small and fed to guppies. Mosquito larvae contain high protein and belong to meat food, and feeding guppies with it can promote the growth of guppies.

In particular, when guppies are fed mosquito larvae during pregnancy, the reproduction rate of guppies will also increase. However, it should be noted that mosquito larvae are prone to polluting water quality, so after each feeding, the water needs to be changed to avoid water infection. In general, feeding mosquito larvae once every two or three days is fine.

2. Guppies eat green moss in the fish tank. Guppy juveniles, in particular, basically live on green moss from fish tanks. Because guppies are only raw, they don't care about feeding, so most of the juveniles feed on their own.

In a small environment, green moss is the best food that juvenile guppies can eat. According to observations, juvenile fish that grew up eating green moss were no different from other fish, and there were no cases of slow growth, anorexia, or illness due to eating green moss. Therefore, guppies can eat the green moss in the fish tank.

It takes half a year for mosquito-eating fish to grow from eggs to growth.

Mosquito-eating fish is a relatively small ornamental fish. Its lifespan is generally between 6-7 years. However, when they are kept at home as ornamental fish, they generally have a short lifespan, generally not exceeding 5 years.

Some novice farmers breed them, and they may die in two or three years. In order to make them live a long life, they need to pay attention to the surrounding environment when breeding.

Mosquito fish lifespan:

The mosquito-eating fish is an ornamental fish that is relatively small in size and has a relatively flat body. They are mainly a wild fish, and the lifespan of wild species is relatively long, generally between 6-7 years. However, if the water environment in which they live is polluted, it will also affect their lifespan to a certain extent.

Recently, they can also be kept at home as aquarium fish.

Compared with wild species, domestic mosquito-eating fish will have a shorter lifespan, generally not more than 5 years. Even some novice farmers breed mosquito-eating fish, their lifespan is only about two or three years, and then they will die due to various reasons.

For example, getting sick and dying, and so on. Therefore, in order to make them have a long lifespan, they need to pay attention to regulating the environment such as water temperature, water quality, food, oxygen, space and other factors, which need to be paid attention to, and only in this way can they provide a suitable environment for their growth.
