The striking black stripes make zebra nerite snails one of the most beautiful freshwater snails commonly available to aquarists. As well as being very decorative the Zebra nerite feeds almost exclusively on algae to the point where algae wafers may have to be fed to supplement the diminishing food supply, even the hard green algae that proves so difficult to remove is on the menu, however despite its appetite for the green stuff, these snails will not eat plants Making them an ideal addition to the planted aquarium.
