Hand-carried from the Florida coast, this Crown Conch was added to my refugium (8/11/03). Fortunately I took a few pictures, because it immediately buried itself in the sand. My Fighting Conch does the same thing for up to two weeks at a time, so I'm not too concerned. I love the shape of the shell, and how it glides across the sand like a hovercraft. Approx. 2.5" in length. It is very likely a carnivore, and it lived for a few years in my system. Not Reef-safe.
