We have been noticing clusters of small (smaller than grain of rice) white snails on sides of tank at night. Because we have ceriths, I assumed these were baby ceriths. They really haven't grown in size, and have stayed white. Luckily, we don't have any clams.
I do have a large plate coral that has been very healthy for over a year. Lately, I have noticed some white skeleton showing on the underneath. These small snails are also near the plate coral. Do you think they are harmful for the plate?
Sorry, I won't be able to take pics of them--too small! But I have seen photos of them and very sure that's what they are.
Also--should I attempt to remove them? (there's so many!)
