Medaka fish are ornamental fish, and they need to know their size before they are bred. Medaka fish is not very large, is a small body of fish. When they grow up, their body length will be between 1.5 and 2 centimeters. Occasionally, there are medaka fish in the size of 3 cm or even 4 cm, which is a relatively large medaka fish, such a large medaka fish is not much.
For medaka fish raised in homes, body length is generally short. Especially for those who have just started farming and have no experience, the development of medaka fish will not be too good, and the size will not be too large. Because of their small size, they do not need a large tank. However, their activity intensity is still relatively large, if you want to breed a large number of medaka fish, you need to choose a larger tank.
Medaka fish live an average of 3-4 years, not a long-lived fish. They will be more sensitive to the surrounding environment, if the environment is not suitable, it will affect their life span. Moreover, their disease resistance is not too strong, so if they get sick, they will die young, which will also affect their life span. Therefore, how long they live is affected by the way they are farmed. If we want to make them live long, we must ensure that the surrounding water environment is suitable, and can not change dramatically, and also provide adequate environment. Generally speaking, if novice breeders breed medaka fish, their life span will not be too long.
