Hang the breeding box on the wall of the fish tank at the height of the breeding and water levels. Place the mother fish to be produced in it, and the fish fry will swim out from the bottom gap to the outside, thus isolating the mother fish and preventing the newborn fish fry from being eaten by the mother fish.
