Snail/Nudis

This is a Whelk, a snail that consumes dead livestock on the reef. It will also attempt to attack and kill snails. These are carnivores. I had at least six of these in my 55g reef for the frist year, and never had a problem. After carefully acclimating a tiny Golden Maxima clam, the next day I found all the whelks finishing off my beautiful clam. They definitely attacked it - as clams are part of their diet - I only learned later. (sigh) NOT Reef-safe at all. It looks like a Nassarius snail! <-- learn how to tell the difference.
