🐌 Checkered Nerite Snail (Nerita tessellata)
Algae Control • Marine Cleaner Snail • Reef Safe Grazer
📋 The Checkered Nerite Snail (Nerita tessellata) is a hardy marine snail well known for its checkerboard shell pattern of alternating dark and light squares. Native to the Caribbean and Western Atlantic, it is an effective reef-safe algae grazer that helps keep live rock and aquarium glass clean.
Unlike freshwater nerites, this species is strictly marine and thrives in reef aquariums. It is peaceful, small, and highly effective at controlling nuisance algae, making it a favorite cleanup crew member.
Because it does not reproduce easily in aquariums, it won’t overpopulate tanks, making it both a functional algae cleaner and ornamental snail for saltwater hobbyists.

✨ Checkerboard shell pattern – attractive and unique
⚪ Excellent algae grazer – reef safe and effective
📏 Small size – ideal for nano and reef aquariums
