Tank compatibility[edit]

An excellent algae eater, when necessary you can supplement with dried seaweed. They can starve if not enough algae is present in the tank.

Feeding regime[edit]

Supplement when necessary.

Environment Specifics[edit]

Prefers cooler temperatures but can tolerate up to 25.6°C (78°F) . Keep with peaceful fish and a tank with plenty of algae growth to graze on. For this reason they do best in mature tanks with well established live rock.


A very peaceful snail which will concentrate its attentions on algae and not harm corals or other reef-dwellers. Benefits from calcium additives and is sensitive to water chemistry.
