How to reproduce red zebra fish

The red zebrafish is bright red with several light pink stripes distributed from the side to the tail, which is very ornamental. So how do red zebrafish reproduce?

How do red zebrafish reproduce?

Red zebrafish reproduce by laying eggs, embryos develop in vitro and are completely transparent. One day of embryo development is equivalent to 21 days of human embryo development in the mother.

II. Precautions for artificial propagation of red zebrafish

1. identification of female and male fish

It is not difficult to distinguish between male and female zebra fish: male zebra fish slender body, fin large, yellow body color, anal fin was brown, striated significantly; female fish body is larger, lighter body color, blue, anal fin was pale yellow, pregnant fish belly expansion is obvious.

2. Water quality temperature requirements

Zebrafish reproduction is not difficult, requiring the pH of the reproduction water is 6.5-7.5, the hardness of the water suitable for reproduction is 6-8, and the water temperature suitable for reproduction is 25-26 degrees Celsius.

3. Dispersal after output

Lay a layer of nylon net board on the bottom of the square tank of 25cm X25cm X25cm, or lay some pebbles, and then fall under the net board or scatter in the gaps of pebbles after reproduction.

4. spawning at the bottom of the tank

Select 2~3 pairs of zebrafish parent fish, put them into the breeding aquarium at the same time, like to lay eggs at the bottom of the aquarium, generally from dawn to about 10:00 the next day.

5. End of Spawning Notice

After the spawning of zebrafish, fish out zebrafish parent fish. The eggs are not sticky and fall directly into the bottom of the tank. By about 10 pm, the eggs that are not fertilized are white and can be sucked out with a straw.

6. Incubation temperature attention

At 24℃, the fertilized eggs hatched in 2~3 days, and at 28℃, the fertilized eggs hatched in 36 hours. Female fish lay more than 300 eggs each time, up to thousands.

7. Summary of larval rearing

The water temperature for larvae reproduction is about 25℃. Larvae will start to eat 7~8 days after hatching. At this time, egg yolk gray water will be fed, and then small fish will be fed.

Red zebrafish temperament lively, mild, can be raised alone or mixed with other small fish, is one of the most popular tropical fish.
