Seven-star swordfish can be mixed with silver arowana and map fish. These fish are similar in size to it, so they will not eat each other. When mixed breeding, be sure to pay attention to the stocking density. Although the seven-star swordfish has a relatively gentle personality, if the fish tank is too small or the stocking density is high, they will also fight for territory.

Notes on the polyculture of Seven Star Swordfish:

1. Polyculture of ornamental fish of the same size is conducive to peaceful coexistence, otherwise big fish will eat small fish. In the end, there were fewer and fewer fish in the tank.

2. Seven-star saury is a large bottom fish with a gentle temperament. Fish mixed with seven-star saury should not be too aggressive, otherwise the seven-star saury will be bullied and oppressed.

3. Seven-star saury is a tropical fish, so you need to pay attention when breeding it together. It cannot be mixed with cold-water fish. Fish species with different habits are most likely to cause problems when mixed together.

4. Although the seven-star swordfish has a gentle temperament, it has a strong sense of territory. When breeding in polyculture, the density should not be too small to avoid fights for territory due to too high a density.
