How do map fish breed?

The whole reproduction of map fish is relatively simple. After natural pairing, we will look for a place with a smooth surface, and then eat it in turn and then begin to spawn. The number of eggs varies from 800 to 2000, depending on the number of species. Then the map fish will take good care of the eggs until they hatch. Let's take a look at how map fish reproduce.

Map fish breeding time

In general, many map fish are raised in the feeding tank, and when they are sexually mature, they will fall in love and find a mate, as long as the natural pairs of parent fish are put into the breeding box. It is an egg-laying fish. the age of sexual maturity of parent fish is 18 months. It can reproduce many times a year, mostly in summer and autumn, and it is not difficult to reproduce.

Map fish distinguish between male and female

It is difficult to distinguish between male and female map fish. Generally speaking, the head of male fish is higher and thicker, the dorsal fin and anal fin are longer, the plaques and stripes on the body are more colorful, the body of female fish is stronger, the anal fin is smaller, and the body color is not as bright as that of male fish. The scientific way is to make a careful observation: when distinguishing the genitals, the male genitals are slightly thin and pointed, while the female genitals are oval.

Map fish breeding preparation

The area where map fish move after maturity is not very large, and the breeding tank is more than 60 cm long, 45 cm wide and 50 cm high. the breeding equipment mainly includes transverse temperature heating tube, oxygen pump, filter, lighting, etc., a smooth marble board (20 cm × 20 cm × 2 cm) should be placed at the bottom of the aquarium box, and the incubator should be 60 cm long and 40 cm wide, and two pieces of oxytetracycline should be prepared at the same time.

How do map fish reproduce

1, after the conditions are available, put into the fish, the first reproduction process is generally relatively long, may take 1 to a few months! Sexually mature species of fish are more sensitive to the breeding board, will often stand upside down with the mouth to add the board, the board is the performance of sexual maturity will not necessarily immediately reproduce. Really fast breeding fish will have protruding genitals and very large genitals before breeding, which is very normal, don't be scared!

2. The parent fish will gnaw out a spawning nest on the slate. The females lay their eggs on washed stones, and the males then fertilize them. The female fish is close to the nest before giving birth, while the male fish swims around the female fish, and the breeding process takes about 3 hours!

3, because the parent fish have the habit of swallowing eggs, so after breeding, it is proposed that the breeding board be put into the incubator for artificial inflatable hatching. at this time, the map is very ferocious, be careful to be bitten! On the other hand, the fertilized eggs hatched brown larvae after 48 hours, and the larvae could swim and feed freely after 5-6 days. Open food should be fed with "migratory water", wait for a week before feeding small fish and insects.
