How to Get Rid of Snails in Your Aquarium

To eliminate snails from an aquarium, it is essential first to understand why snails appear in the aquarium.

The reason snails appear in aquariums is primarily due to aquatic plants, decorations, or substrate introduced into the tank. Whether the aquatic plants or substrate are purchased from a pet store or given by a friend, if they are not properly treated before being added to the aquarium, there is a high likelihood that snail eggs may be introduced along with them.
