Description: The Hairy Snail has an unusual-look with delicate, rear-facing, needle-like protrusions on the shell. The body of the snail is light brown or reddish-brown. When at rest, they usually bury themselves into a soft substrate, so a layer of fine aquatic sand on the bottom of the aquarium is preferable to gravel, as it will protect the fragile periostracum spikes. These snails are great algae eaters and they can be a good choice in planted tanks, however they might eat soft-leaved plants if other food sources are scarce. The water should be moderately hard and alkaline to allow for healthy shell development, because in softer water, where the calcium concentration will be lower, the snails will be very prone deterioration of the shell. Their aquarium must be covered, as they are excellent escape artists, but it is best to maintain a water line slightly lower than the lid to allow them to move in and out of the water. Be very careful when handling these snails as the long, thin spines can pierce the skin.
