From your description, it seems that zebrafish will give birth to small fish, but zebrafish does not directly give birth to small fish. It will lay eggs first, and then the eggs will hatch and turn into small fish. Zebrafish are oviparous fish and usually lay eggs at the bottom of the aquarium. When the water temperature is maintained at 28°C, zebrafish eggs will hatch into larvae in 36 hours. The reproductive cycle of zebrafish is about 7 days, and it can reproduce 6 to 7 times a year continuously, and the number of eggs it lays is high. Its fecundity is very strong.

Zebrafish is a common tropical fish. Zebrafish are slender, with an adult body length of 3~4cm, and do not have high requirements for water quality.
