Adding medicine: You can also fish out all the fish in the fish tank and add some aquarium medicine that can kill snails, so that all the snails can be cleaned up.
Cleaning the fish tank: you can also clean the fish tank thoroughly, so that all snails can be cleaned up.
Why are there snails 1 in the fish tank? Other fish carry: fish tanks used at home generally don't grow snails by themselves. If snails appear in the fish tank, they may be taken away by other fish. For example, breeders catch some wild fish and keep them in fish tanks. Snail eggs are attached to fish, and after a period of incubation, snails will be born.
2. Carrying of aquatic plants: It may also be carried by aquatic plants newly put into the tank. Snails like to lay eggs on aquatic plants best. If aquatic plants are not disinfected before entering the fish tank, snails will hatch and breed in the fish tank.
