Last Updated: 2024/11/22, 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. Zebrafish are oviparous fish, 4 months into sexual maturity, generally 5 months old fish reproduction is better. Zebrafish reproduce relatively easily. The reproduction water requires pH 6.5 -7.5, hardness 6-8, and water temperature 25-26 degrees Celsius. Zebrafish are most fond of

It is not difficult to distinguish between male and female zebrafish: male zebrafish is slender, the fin is large, the body color is yellow, the anal fin is brown, and the stripes are prominent; the female fish is larger, the body color is light, blue, the gluteal fin is light yellow, and the abdomen of the fish is dilated obviously during the pregnant period.

Zebrafish is an egg-laying fish, 4-month-old into the sexual maturity, generally used 5-month-old fish reproduction is better.

Zebrafish can reproduce more easily. The water for reproduction requires pH6.5-7.5,6-8 hardness and 25-26 degrees Celsius. Zebrafish like to eat their own eggs, so the breeding tank is covered with small stones and aquatic plants to facilitate the attachment of eggs. When breeding, it can be prevented into the breeding tank according to the ratio of 1:2 between male and female, which is generally prevented from entering the night before, and can be spawned and fertilized at noon or in the morning the next day. Fish should be fished out and reared after ovulation. A female fish can ovulate 300-1000 eggs at a time.

The fertilized eggs can hatch the larvae after 2-3 days, and then the larvae begin to swim for food after 2 days. They are fed with "migratory water" at first, and can be changed to other small fish and insects after 10 days.

The reproduction cycle of zebrafish is about 7 days. Zebrafish can reproduce 6-7 times a year continuously, and the number of eggs laid is high.
