with goldfish? Medaka can't be raised with goldfish. Although they are mild and can adapt to the water temperature between 0 and 32 degrees Celsius, the size difference between medaka and goldfish is too large. If they are mixed together, medaka can easily be eaten by goldfish. Because the body length of adult goldfish can reach about 20-30 cm, and the body length of adult medaka can reach up to 4 cm, the size difference between the two kinds of fish is too large to be mixed together. And when feeding, goldfish will grab food, medaka is small, in general, it can not grab goldfish, if the medaka has no food for a long time, it will lead to their stunting.
with? The mosquito eater is more suitable to be raised with the medaka. Both of them are omnivorous fish and prefer to eat mosquito larvae. And the personality is relatively mild, the size difference is not big, mixed breeding together will not produce a lot of conflict. And their habits are similar, so they do not need to deliberately regulate the surrounding environment if they are mixed together.
But in polyculture, we should also pay attention to the number, because the medaka has a strong sense of territory, if the space is small, it will conflict with the mosquito fish. When feeding at ordinary times, it is necessary to ensure adequate food, which can effectively avoid their fighting for food.
