First of all, keep the water well. In the process of nourishing water, adjust the water to weak acidity. You can put 1-2 orchid leaves and prepare a 40 cm jar. If possible, you can match a 60-cm fish tank, put ceramic pieces in the fish tank, or buy small columns specially for swallowtail fish on the Internet.

Female fish should choose a fat belly and healthy body, and it is best to let the fish pair freely. You can raise 6-8 to facilitate their self-pairing, so that the success rate of reproduction will be higher. Generally, when pairing, swallowfish will lay their eggs on ceramic pieces or special spawning columns prepared in advance. But at this time, other fish should be isolated to avoid stealing fish eggs.

Newborn small fish will follow big fish, and hatched small shrimp can be fed with open feed. Don't feed it for the first two days, because there are some egg yolks to eat. Until the parent fish let them swim by themselves, about 1 cm, they can live independently. Change the water properly during the period. If feeding is frequent, change it once every three days and change it by one fifth at a time. Siphon the residue at the bottom of the tank.

Life habits of swallowfish

Swallow fish is very gentle and has no special requirements for water quality. It can be mixed with most fish in weak acidic water. The only thing that needs attention is the tiger skin fish of CYPRINIDAE. These naughty and lively fish often like to bite the anal fin and caudal fin of swallowfish. Although it is not a fatal attack, in order to maintain the beauty of swallow fish, we should try to avoid mixing swallow fish with them.
