1. Reason: Map fish biting each other may be caused by insufficient living space. They belong to medium-sized fish, with a body length of about 30 cm in adulthood and a strong sense of territory. If they don't have enough living space, it is easy to fight.
2. Solution: Breeders need to separate them or replace them with a larger fish tank, so as to ensure that they have enough room for movement.
2. Competing for food1. Reason: It is also possible that map fish bite each other because they are competing for food. Map fish is a kind of fish that is greedy and has a high demand for food. If the breeder can't guarantee that they have enough food, they are also prone to fight.
2. Solution: Breeders need to feed them regularly and quantitatively, so as to ensure that they can absorb nutrition better and have enough food.
3. In estrus1. Reason: It is possible that map fish bite each other in estrus, and their personality is fierce. In addition, when they are in estrus, their temperament will be extremely irritable.
2. Solution: Breeders need to isolate them properly. If they want them to breed, they can install a partition in the fish tank to avoid fighting. If breeders don't want them to breed, they can breed them separately, and then put them together after they have passed the estrus period.
