This is what melevsreef has to say
This tiny snail is a predator of zoanthids, and may be tough to see in your tank. Watch your zoos closely at night for this Sundial Snail, and if you discover one be quick to remove it. For the next few days & weeks, keep watching when the zoos are closed up, in case any baby pyramid snails appear Not reef-safe
