Tiger Blood Nerite Snail
Couldn't load pickup availability
The tiger blood snail, or tiger nerite snail, has a distinct wavy pattern on the shell and loves algae. These snails do not harm plants or overrun the aquarium. Nerites only grow to a little less than one inch, so several would be needed for effective algae control in an aquarium of ten gallons or more.

Care Guide
Tank setup: Nerites do well in most established tanks with algae to graze. Keep the water hard and alkaline for healthy shells, and keep a lid on the tank, since nerites sometimes climb out. If one flips onto its back, turn it over, since some can't right themselves.
Feeding: Nerites mostly graze on algae. If the tank is very clean, add algae wafers so they don't go hungry.
Tankmates: Nerites get along with peaceful fish, shrimp and other snails. Avoid puffers, loaches and large cichlids, which eat snails, and keep them away from assassin snails.
Good to know: Remove snails before treating the tank with copper or other medications, which are toxic to invertebrates.
