nassarius vibex snail is a small carrion snail, which means it
only feeds on dead or decaying animals. It's a useful tank cleaner
as it has a very large appetite and will consume any uneaten food
or dead organisms in the aquarium. This particular snail will not
eat macro or micro algae and will not prey upon other live snails
or invertebrates in the aquarium. We recommend only a few per tank
because they need to be well fed. Sizes range from 1/8" to
about 1/4" long.
