1. Constant water temperature: Swallow fish are tropical fish, and they prefer to live in water temperature between 24-28℃. When raising artificially, it is necessary to keep the water temperature between 24-28℃. If conditions permit, you can install a heating rod to keep the water temperature constant.

2. Clean water quality: Swallow fish like clean and refreshing water quality. If the living water quality is too poor, their fins and body color will be affected. When artificial breeding, you can change the water every 3-5 days to keep the water clean and fresh.

If conditions permit, a circulating filter can be installed to slow down the deterioration of water quality.

3. Reasonable feeding: Although swallowfish prefer animal feed, breeders should try not to feed only the same food. It is best to feed animal feed together with plant feed, which can not only ensure their adequate nutrition, but also avoid the situation of single diet.
