Sexing[edit | edit source]

Tank compatibility[edit | edit source]

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

Diet[edit | edit source]

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

Environment Specifics[edit | edit source]

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.

Behaviour[edit | edit source]

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.

Identification[edit | edit source]

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