in the fish tank, they need to be cleaned up as soon as possible. The simplest way is to fish them out manually. However, this method can not eradicate the snails. If there are snail eggs hidden in the invisible place, they will soon hatch new ones. Therefore, it is better to keep some fish or snails that can eat snails, such as Malay snails, killer snails and chocolate dolls, which can play a continuous cleaning effect.

2. Why there are snails

1. New fish: There are snails in the fish tank. In many cases, new fish are brought in. In order to avoid this situation, it is better to disinfect the new fish before it enters the tank. Soak it with potassium permanganate into dissolved oxygen with low concentration. In this way, snail eggs can be killed and hatched in the tank.

2. Water plants: Water plants in the tank may also bring snail eggs into the tank, and this situation is almost impossible to deal with, so we must choose a better quality shop to buy water plants, so that the safety will be higher. It is worth mentioning that if it is a grass tank, there is no fish and shrimp, you can use some snail medicine, the effect will be better. But if there are fish and shrimp, it will not work, and it will cause harm to fish and shrimp.

3. Live baits: If live baits are used to feed fish at ordinary times, they may also carry snail eggs or larvae, which will hatch snails if they are not eaten in time when they enter the water. Therefore, it is better to feed live bait after freezing treatment, which can also play a role in sterilization.
