Why do fish bite each other (detailed introduction)

Fish biting each other is a common behavior that often occurs in situations of lack of food, territorial disputes, courtship, competition, or other stressors. Here’s a detailed look at fish biting each other:

1. Food competition:

Fish in resource-scarce environments, such as overfished waters, may exhibit intense competition for food. In this case, fish may bite each other to compete for food sources, especially if food supply is low.

2. Territory competition:

Fish often establish territories and fight to defend or compete for them. Biting each other may be a form of aggressive and defensive behavior between fish during territorial competition.

3. Courtship behavior:

Some fish may display aggression during courtship season, including biting each other. This behavior may be an attempt to compete for a mate or to demonstrate one's superiority.

4. Social structure:

Some fish have strict social structures, including leaders and order. In such social structures, biting may be done to establish or maintain status and hierarchy within the group.

5. Stress and environmental factors:

Fish may be affected by environmental pressures, such as water quality problems, habitat disturbance, etc. These pressures may lead to stress and conflict between fish, leading to the behavior of biting each other.

6. Behavioral Investigation and Learning:

Sometimes fish may bite each other to investigate each other, learn from each other, assess potential threats, or find potential partners.

In general, fish bite each other usually due to the combined effects of resource competition, territory competition, courtship behavior, social structure, environmental pressure and other factors. This behavior is a natural part of fish, which is how they deal with their inherent competition and conflict, maintaining social structure and balance among individuals.
