An LFS near me had one as well...I can't imagine why anyone would want that in their tank. Especially since they can get rather large. 5' long or so. I worked on a charter boat in Savannah, GA for a while and some of our charters would try and catch them. They never understood why the captain and I got so mad about that. Well they did after we got them on the boat. They bleed worse then a hog.
