medaka reach maturity when the body size reaches 2-3 centimeters, that is, about 4-6 months after birth. Medaka are ovoviviparous, which means that they are small fry when they are born, so their body length can reach 0.3 centimeters after birth. The growth rate of medaka is faster, about a week after birth, their body length can reach 0.5 centimeters. It can grow to about 1 centimeter in about one month after birth. Half a year after birth, they will mature, and their size will be about 2-3 centimeters. If there is a good constitution, the body length can also reach 4 centimeters. The adult time of medaka is closely related to the breeding environment. If the environment is suitable, their adult time will be shortened, and they can mature in about 4 months. If they are kept in a poor environment, they will be adults for a longer time.
of medaka is about 3-4 years. They are sensitive to environmental changes. If the breeding environment is poor, it will affect their life span. And their disease resistance is weak, if they often get sick, their life span will be relatively reduced, so how long they can live depends on the environment in which they are raised. If breeders want them to live longer, they need to provide them with a good living environment and ensure the stability of the surrounding environment.
