The Banded Trochus Snail, also known as the Trochus Snail, Turban Shell, Turban Snail, or Top Shell, is shaped like a top or pyramid. The shell usually is a pale color with maroon stripes, though it is often covered with algae. (Snails of the Trochus genus are also called Turban Snails.) Depending on the exact species these snails may have either a black or an off white/tan foot. It can grow to about one inch.

It does well in an aquarium when provided with ample hiding places and room to forage. Live rock provides algae, cyanobacteria, and diatoms for food, but it also is an effective film algae eater, grazing on other surfaces, such as the sides of the tank. It is sensitive to high levels of copper-based medications and will not tolerate high nitrate levels.

It has no distinguishing characteristics to help differentiate male from female. They reproduce by releasing gametes into the water column, which appears as a white milky substance.

Unlike Astraea Snail, Trochus Snail can right itself if falls.

If insufficient food is present in the aquarium, supplement their diet with dried seaweed.
