Hump hangings can breed. It is best to pick out a pair of fish that is placed in the breeding tank on the same day or even that night, and breed in the early morning or morning of the next day. Specifically, count how many days it has been since some females last spawned, and the number of days in this cycle is regular.

After a certain pair occupies a site, the hump cranes can be moved to the production cylinder. Several small pottery urns should be placed. Under the water temperature of 29°C, the hatched larvae will be hung on the snapper pots and bricks with head silk for about two and a half days.
