They were changed from genus Nassarius to genus Ilyanassa in the 70's.

Nassarius vibex are a different snail and a more appropriate species.

Ilyanassa is not a reef snail at all. As a snail from cold and temperate water, keeping them at reef temperatures is sentencing them to a premature death. In addition, they aren't entirely reef safe, especially in tanks with sand beds.

They are an intermediate host for nine species of trematode fluke. (swimmers itch)
