. Although fighting can make them more energetic and in better shape. But fighting can damage their body surfaces and cause them to get hurt. Therefore, it is better to avoid fighting with them in daily feeding. They can be raised separately, and if they are separated, they will not be able to fight. But keeping them alone will reduce their fighting ability, so we can put some live bait on them to improve their vitality. You can also give them a bigger fish tank. If the fish tank is bigger, the chance of meeting them will be reduced, and the big fish tank can provide them with enough living space.

Two, the same fish tank to raise several Luohan fish,

the same fish tank to raise several Luohan fish, it depends on the size of the fish tank. If the fish tank is relatively large, it can provide sufficient living space for Luohan fish. At this time, you can raise a few more, but it's better not to exceed three, otherwise they will fight if there are too many. In the process of fighting, they will be injured, and if their wounds are not treated in time, they will rot and get sick. Moreover, the excrement of Luohan fish is very large, if the number of feeding is too large, it needs to clean up the water quality frequently, which increases the workload, and if it is not cleaned up in time, it will pollute the water quality. If the fish tank is small, it is better to keep only one.
