How to distinguish male and female zebrafish

The appearance of the red zebrafish is bright red, which is very ornamental. It is also very small, usually between four and six centimeters. The red zebrafish is very lively and gentle. It can not only be raised alone but also mixed with some small fish. For breeders, it is necessary to distinguish between male and female zebrafish, which is conducive to reproduction. So how to distinguish between male and female zebrafish?

First, how do you tell the male and female zebrafish apart? Male zebrafish have slender bodies, large fins, yellowish body color, brownish-yellow anal fins, and obvious stripes; female fish have fatter bodies, lighter body color, more bluish, light yellow anal fins, and their abdomens swell noticeably during pregnancy. If you are just starting to raise zebrafish, the merchant will definitely tell you which is a male zebrafish and which is a female zebrafish before you buy it. If you forget, you can choose to check it when it is a little older so that it is easier to confirm.

Second, after identifying the male and female zebrafish, the female zebrafish that has grown to about 4 cm in size has basically entered the mature stage and can undergo in vitro fertilization and lay eggs. You can lay a layer of pebbles or other useful objects at the bottom of the breeding box in advance to prevent the mother zebrafish from swallowing the eggs after laying them.

Third, zebrafish has strong adaptability. It is kept in water temperatures of 20-23℃ and can still survive in water temperatures of 11-15℃. It has strong heat and cold resistance and can grow well in water above 10℃. It is a low-temperature and low-oxygen fish with low requirements for water quality and can utilize water ranging from weakly acidic water to neutral water. In addition, you must not use untreated water directly. It should be dried for 1 day and filtered and oxygenated before use. Red zebrafish like to eat red nematodes, blood worms, etc. They can also be fed with pellets, 2-3 times a day, and feed them after they have eaten a small amount. The remaining bait should be removed in time to avoid damaging the water quality. It is worth noting that zebrafish like to lay eggs at the bottom of the aquarium and like to eat their own eggs, so be careful. When raising zebrafish, you must pay attention to proper lighting, but be careful not to expose them for too long. If exposed to light for too long, the color of the fish will fade and algae will bloom in the fish tank, making it difficult to clean.
