After this, the male will deposit sperm or milt at the entrance of the cave, and both of them will fan the milt with their fins to fertilize the eggs. There can be around 200 eggs, and after the fertilization process, the female fish protects the fish inside the cave and the male fish guards from outside.

– Post Breeding Care

The eggs will hatch in a week, and the fry will come out. By this point, the fry and the female fish should be separated as the male fish will try to eat the fry.
