I ordered a fighting conch a while back from reef scavengers http://reefscavengers.com/fightingconch.html. It is quite odd - he just doesn't move. For a couple of days every month he walks all around the tank bottom. Just hanging around seeing what is out there. Assume he is eating too. Then he buries himself leaving one eye/antenna sticking out of the sand. Stays in the exact spot for weeks if not a month at a time. Do any of you have more active conchs?
