This small white, one eighth of an inch (2 mm), cone-shaped snails feed upon Tridacna clams and is in the family Pyramidellidae. It can multiply quickly at a very small size, and in large numbers can be a serious threat to any clams in the aquarium. Typically, they can be found along the clams upper edges where the mantle overhangs, especially during nighttime feeding time frames. During the daytime, they may be either located at the foot area, or tucked away along the ridges on the shell.
