Tank compatibility[edit]

Peaceful reef-friendly snail. An essential part of the clean-up crew. Avoid keeping with aggressive invertebrates such as Mantis shrimp.


Grazes on algae, mainly cyanobacteria and diatoms. Diet can be supplemented with blanched spinach or lettuce, and vegetable based tablet foods.

Environment Specifics[edit]

Can be sensitive to water quality, will not tolerate high nitrates or any copper-based medication in the tank. Prefers a tank with lots of live rock to craze on and hide amongst. Will be happy as long as there's algae for them to eat. Needs an SG of 1.023-1.025.


Will be found constantly grazing around the tank. Must be observed regularly as if this snail falls on it's back, it will not be able to right itself.


Olive green rough cone shaped shell, pale flesh. Has excellent camouflage when hiding in live rock.
