An easy, peaceful snail that is with caution in a reef tank, that gets to about four inches. They prefer to be in a tank with more rock and more hiding spots. At a smaller size it'll eat algae and scavenge for scraps, but at it's fully grown adult size it will eat some anemones, sponges, and soft corals. They're best housed with urchins, starfish, and tube worms. They don't tolerate copper based medications and need low nitrate levels.
