Why do fish bite each other?

Fish bite each other for a variety of reasons, and often this behavior is common in fish societies. Here are some possible reasons:

Competition for food: In captivity or in nature, fish may compete for food, especially when space is limited or food resources are scarce. Stronger or more aggressive fish may bite other fish to maintain their position in the food chain.

Territorial defense: Some fish are territorial and will observe and defend an area of their own. When other fish enter the area, attacks or fights may result, including biting each other to protect territory.

Courtship behavior: Fish biting each other may also be related to courtship behavior. Some fish engage in "mouth-slapping" with their lips or other means as part of courtship behavior to express interest in a mate.

Social status and group structure: In some fish societies, clear social status and group structure exist among members. Certain fish may use biting or other behaviors to assert their position within the structure or to demonstrate superiority.

Illness or illness: Occasionally, fish biting each other may mean that some fish are unwell or suffering from disease. Fish bite other fish when they are in pain, discomfort or when they are fighting.

It is important for breeders to understand the reasons behind these behaviors, especially in captivity, and these biting behaviors can be reduced by providing more space, rational distribution of food, and providing suitable shelter. In natural environments, this behavior is usually for survival and reproduction.
