1. Reason: Map fish may not eat because they are frightened. Although they are large in size, their courage is still relatively small. When they are raised artificially, if there is a loud noise or beating the fish tank hard, map fish will be frightened.

2. Solution: Breeders need to keep their living environment quiet. If the frightened situation is serious, they can cover the fish tank with a black cloth to increase their sense of security. After they recover from the frightened state, try to feed food again.

1. Reason: Map fish don't eat because the food they feed is not appetizing. They are omnivorous fish. If they feed the same food for a long time, they will refuse to eat.

2. Solution: Breeders can try to feed other foods, such as live bait such as small fish and shrimp, or lean meat and beef heart.

1. Reason: It is also possible that map fish don't eat because the living water temperature is too low. They are tropical fish and like higher water temperature. If the temperature is too low, their appetite will also decrease.

2. Solution: Breeders need to raise the water temperature to between 24-26 ℃, and then try to feed food after they adapt to the new temperature.

1. Reason: Map fish may not eat because of illness, and most diseases will lead to loss of appetite.

2. Solution: Breeders need to judge the cause according to their condition, and finally treat them symptomatically.
