There are many kinds of tropical fish, but as long as they are similar in size and habits, they can be mixed together. If the body shape of mixed fish is too different, the big fish will swallow the small fish, in addition, do not mix some aggressive or territorial varieties, otherwise they will fight in the fish tank, causing unnecessary losses.
1. Similar size: In polyculture of any fish, it is necessary to choose a species of similar size, because in the world of fish, it is natural for big fish to eat small fish. If they are mixed together, the small fish will disappear in a few days.
2. Similar habits: The problem of mixed culture of tropical fish is not big, because everyone has similar requirements for water temperature, which is basically between 20-30 ℃. However, some fish like acidic water quality, some fish like alkaline water quality, so when mixed culture should also pay attention to, otherwise it will make the fish in a bad state.
3. Consistent feeding habits: Another problem to be noted in polyculture of tropical fish is feeding habits. If fish have different feeding habits and eat each other's food, there will inevitably be some problems, if they all use artificial feed, it is easy to be picky for a long time, so they also need to be fed with other feed.
4. Density of mixed culture: Since it is mixed culture, we still need to consider the density of culture. It is best to have some fish in the upper layer, some in the middle layer, and some in the lower layer. This is also more beautiful. If they are all crowded together, they will have problems.
