, first of all, the male fish and female fish should be separated, do not let them mate. The number of breeding can be greatly reduced. Although they are separated, if there is a female fish that has mated before, the sperm of the male fish will be preserved in the body, so even if they are separated, they will lay eggs, but the number will be reduced. If the mother fish lays eggs, she can eat the eggs directly without isolation. This also reduces the number of hatches. If it is a hatched fish, it can be raised in a separate container for several months, and when the fish grows to about 4 centimeters, pick some of the better ones to stay, and release the rest directly.
small guppies that don't want to be raised? 1. Guppies with better shape and color can be given away or sold to aquariums, or they can be exchanged for feed with aquariums. Generally, fish friends who have raised fish for a long time will operate in this way.
2. The hatched fish can be fed to other carnivorous fish as fish food, which can not only reduce the number of guppies, but also supplement the nutrition of other fish. Newly hatched fish are free of bacteria, so there is no need to worry about bacteria or parasites.
3. You can release grown guppies, but you should choose a good place to release them, otherwise they are likely to be eaten by other carnivorous fish.
