These beautiful little snails are great algae eaters. We watch them eat slime algae off rocks in the wild and off of our glass in captivity. They are true marine nerites. These snails do not get very big; about the size of a woman's thumbnail. We have found at least 6 different beautiful shell designs and personally collect them in the Florida Keys. They have been known to reproduce in captivity. The Virgin Nerites are native to the Bahamas. We have tapped into one of the only known areas in the U.S. where these snails reside.
