Map fish have no fish to fear, but their natural enemy in the country of origin is red-tailed catfish. Because red-tailed catfish is large and fierce, they like to eat some fish smaller than themselves, especially map fish. But if the red-tailed catfish is about the same size as the map fish, the map fish can also resist their attack.

Map fish can mix with parrot fish, lucky cat fish, seven-star swordfish, silver dragon fish and ruby fish.

The color of parrot fish is bright, and it will be more ornamental when mixed with map fish. They all belong to tropical fish, which are similar in size and habits, and are very suitable for polyculture together.

Seven-star swordfish, like map fish, is a fish with solid skin. They have low requirements for water quality, and the seven-star swordfish has a mild character and will not take the initiative to attack map fish.

Silver Arowana is large in size, but as long as there is enough room for breeding, they generally do not take the initiative to attack other fish. Moreover, they like to live in the upper layer, which does not conflict with the area where map fish live, and generally does not fight.

1. There is plenty of space: the size of map fish is too large, and the polyculture fish are all of the same size. Breeders need to prepare a larger container for them to ensure that they have enough room for movement.

2. Adequate food: Map fish are greedy and eat a lot. If there is not enough food, map fish will attack other fish.
