Yes, aquarium snails do burrow. Burrowing is a behavior that helps them to find food, hide from predators and regulate their body temperature. When an aquarium snail gets the urge to burrow, it will use its foot to dig into the substrate of your tank. It does this by using its muscular foot in a circular motion which causes sediment particles to stick together and form a tunnel or cavity for the snail. This creates a safe place for the snail where it can lay eggs, feed on algae and organic matter, as well as protect itself from predators such as fish or other invertebrates in your tank. Aquarium snails are also known to cover themselves with sand while they’re buried underneath so they can remain hidden if necessary. While some species may be more inclined towards burrowing than others, all types of snails have been observed engaging in this behavior!
