What is its maximum size?
Typically around 2–5 cm in shell length, depending on the species.
Where is its origin and where is it exported from?
Cerith Snails are found in tropical and subtropical marine waters around the world, including the Indo-Pacific, Caribbean and other coastal regions. They are exported for the aquarium trade from various countries, depending on the species.
Is it reef compatible?
Yes, reef safe. Cerith Snails are excellent members of a reef clean-up crew. They graze on algae, diatoms and detritus, helping to keep aquarium glass, rockwork and sand clean.
What should I feed it?
They mainly feed on algae, diatoms, detritus and leftover organic matter. In aquariums with limited natural food, supplement with algae wafers or small amounts of suitable marine algae-based foods.
How many can I keep?
Can be kept in groups. The appropriate number depends on aquarium size and the amount of algae and detritus available. Avoid adding too many at once, as they may run out of food.
How compatible is it with other fish?
Generally peaceful and compatible with most reef fish, corals and invertebrates. However, avoid keeping them with animals that prey on snails, such as certain triggerfish, large wrasses and pufferfish.
