The diet of the Common Eastern Nassa consists mainly of carrion and some eggs of certain sand-dwelling polychaetes. The Nassa comes out of the sand to eat the carrion and, most of the time, it must move up-current to eat. Obligate carrion-feeders are those animals that will not harm most or all other animals in the systen in which they are living.
The Nassarius Snail is a small scavenger with an oval, spiral shell that resembles an olive pit. The Nassarius Snail likes to burrow in the sand, usually with its long, tube-like siphon protruding from the substrate. As it searches for food, the Nassarius Snail helps prevent compaction and aerates aquarium substrate.
The Nassarius Snail prefers an established aquarium with live rock and a deep sand bed. It is sensitive to high nitrate levels and copper-based medications. The Nassarius Snail is extremely difficult to breed in captivity.
