1. Pay attention to feeding: Arhat fry have a large demand for food, and breeders should ensure their adequate nutrition at ordinary times. If you want them to start, you can feed them regularly to promote the start. But don't feed too much, otherwise it will backfire.

2, add sandbag fish: Breeders can also add sandbag fish, because Luohan fish has a strong sense of territory. After adding sandbag fish, they will feel that their territory has been invaded, so that the fighting spirit of Luohan fish will be raised. However, it should be noted that the size of sandbag fish should be smaller and the aggressiveness should not be too strong.

3. Look in the mirror: If there is not enough room for breeding, you can put a mirror in the fish tank. In this way, the self in the mirror will be regarded by them as an invading kind, and they will open their gills, spread their fins and make a fighting posture to scare away other fish. It should be noted that you should not look in the mirror for too long every day.

4. Environmental stimulation: Breeders can also stimulate them by heating up and cooling down, and the water temperature can be raised by 2 ℃ first, and then raised after the water temperature is lowered by 2 ℃. Repeating it several times can also promote them to start.
