When glass lesbian fish reproduces, the water temperature should be controlled between 27-28 ℃, and the water quality should be neutral hard water. Breeders can choose tap water to dry for about a week as their breeding water. Then plant some aquatic plants in the breeding tank, or lay a layer of hair aquatic plants on the bottom of the tank, thus completing the preparation before breeding. After being prepared, the breeder can put the estrus glass lesbian fish into the breeding tank, and they will keep chasing each other. In the process of chasing, they will hide in aquatic plants to lay eggs, and their eggs are relatively small, which is difficult for the breeder to find without careful observation. Fish eggs will hatch about 24 hours after birth. Generally, small fish can swim on their own after being born about 3 days. At this time, breeders can feed them food.

Small glass lesbian fish are just born, and their size is relatively small. Breeders can feed them some cooked egg yolks. When feeding, they need to use a 200-mesh net, filter the egg yolk water, and then drip it into the fish tank with a straw for the small fish to eat. If the yolk water is not eaten, the breeder had better find a way to clean it up.

When young fish are born, their physique is weak, so breeders need to keep the water temperature at 27-28 ℃, and the water temperature can be gradually reduced during their development.
