How do swallow fish breed?

Swallow fish, also known as fairy fish, angel fish. It also has no special requirements for water quality and can be mixed with most fish in a weakly acidic water environment. So, how do swallow fish reproduce?

How do swallow fish reproduce

1. Spawning

Swallow fish is an egg-laying fish, but it is relatively simple to reproduce. Take a close look at successfully paired Pisces. If a protuberance begins near the anus, that is, the vas deferens and spawning ducts begin to sag, which is a sign before spawning, they will choose an area they think is safe before spawning. Females and males peck at the spawning area clean, and then the females begin to spawn, while the males are fertilized while the females lay eggs. In general, the whole spawning process will last for several hours, and the number of eggs will vary from 400 to 1000 depending on the size of the fish.

2. Keep the eggs

After spawning, females and males jointly guard the eggs and take turns fanning the water with pectoral fins to ensure that the fertilized eggs have sufficient water-soluble oxygen. When some fish eggs become white and moldy because they are unfertilized or infected by water mold, they will immediately peck at them to ensure that other fertilized eggs are not infected. The whole maintenance process is very touching.

3. Take care of the fish

After 36 hours of such no-food or drink management, the larvae began to hatch, but still could not swim, and clung to their place to absorb their own yolk for a long 4-5 days to free the spawning site and feed on tiny water fleas. In the meantime, female and male fish are still frightened and take good care of them. Therefore, in order to create a good and safe spawning environment for them, it is best to put them in another aquarium for breeding when there are signs of spawning, and at the same time provide sufficient water-soluble oxygen with the aid of an air pump. during this period, it is not easy to excessively strong lighting, nor is it easy to make them excessively frightened, which will cause them to devour all the eggs that have been laid. There is no need to feed bait to avoid polluting the water quality, especially the live bait! A kind of cyclopsylla mixed in water fleas can penetrate the outer wall of fertilized eggs and greatly reduce the hatching rate of fish eggs!
