🐌 Checkered Nerite Snail (Nerita tessellata)
Marine Reef-Safe Cleanup Crew • Checkerboard-Patterned Algae Grazer • Peaceful Rock & Glass Dweller • Beginner Friendly Marine Invertebrate
 
📋 The Checkered Nerite Snail (Nerita tessellata) is a small, hardy marine snail instantly recognisable by its distinctive checkerboard shell pattern of alternating dark and light squares.
Native to intertidal rocky shores across the Caribbean and Western Atlantic, Checkered Nerite Snails are true marine snails — unlike some nerite species that tolerate brackish or freshwater, this one is strictly saltwater and belongs in a marine or reef aquarium.
Naturally peaceful and constantly grazing, this species spends its time steadily working across live rock and glass, consuming film algae, diatoms, and cyanobacteria. It's genuinely effective at keeping surfaces clean, though it won't touch most display macroalgae. One thing worth knowing honestly: this species typically has a shorter lifespan than some other cleanup crew snails, commonly around a year in captivity, and it rarely reproduces successfully in home aquariums, so it won't overpopulate your tank but also won't replace itself.
With stable water parameters and a securely covered tank, it thrives as a Small, Effective Reef Cleanup Crew Member.
