If there are snails growing in the fish tank, you can use the following three methods:
1. Remove them by hand: If there are not many water snails in the fish tank, just fish them out.

2. Add potassium permanganate: You can add 1.5% potassium permanganate to the fish tank to kill water snails.

3. Water snail remover: You can first expose the fish tank to the sun, and then use a water snail remover to kill water snails.

Tip:

Water snails reproduce very quickly, so when you find water snails in the fish tank, you must remove them immediately to prevent the number of water snails from increasing. However, if the fish kept in the fish tank are relatively large, or there are scavengers No big deal then, they will clean up the water snails on their own.
