swamps, this snail is also classified as Vittina turrita, and is sold in the freshwater aquarium trade under the common name "tiger nerite" or "tiger snail." Adults may thrive in fresh water with sufficient dissolved minerals. The species has separate male and female individuals; females lay eggs, which hatch into larvae that can survive only in brackish water. Adults grow to about 2.5 cm, and show a pale tan body with a darker tan shell, sometimes brownish or reddish, marked by black bands of varied width. The head has two short antennae which protrude from beneath the shell, each with a small eye at the base (generally invisible beneath the shell). Nerites are slow-moving snails that travel over rocks or hard substrates and do not burrow. Like other members of its genus, the species grazes on algae which it rasps from surfaces with its

for freshwater aquaria. It is considered a desirable snail for home aquarists because of its attractive pattern, compatible requirements with common freshwater aquarium fish, and the fact that it consumes algae without eating plants or overpopulating in home freshwater tanks.
