It is not recommended to raise small arhats fry in one piece. Because their temperament is rather irritable, if they are raised together, they may attack each other because they compete for living space and food, which is very unfavorable to their healthy growth. It's better to have a fish and a tank.

They eat a lot and defecate a lot. If they are raised together, there will be a lot of feces and food residues in the water, thus polluting the water quality. Therefore, you can choose a large fish tank, and use glass to separate them for breeding. Or just put them in a fish tank.

When raising arhat fish, it is necessary to choose water with good water quality. Because they have high requirements for water quality, if the water quality environment is not suitable, the appetite and growth rate of young Arhat fry will be affected. They can be raised in soft water with weakly alkaline temperature of 22-26 ℃, which is the most suitable water for their survival. It should also be noted that the food residues in the fish tank should be salvaged from the water in time after feeding. At the same time, it is necessary to change water regularly, two to three times a week. It is not advisable to change water too much each time, and it is enough to change about one quarter to one third each time.
