conch

So I have a bare bottom tank so one day I can have encrusting corals all over the bottom. But for now, it's just bare bottom. I am a big fan of the fighting conch, however, I don't know if it would do well without sand. Can someone confirm this?

Hi folks-- I found this on my DT glass one night--is it safe to have in my reef tank? Is it some sort of conch? I also wonder how big it will get? Thx much in advance for any help!

Found what I believe is a yearling Fighting Conch washed up on a beach this last week. Brought him home and set him up with Nature's Ocean sand, 'bacteria water', a water mover/filter system & heat from a large local fish store. He seems happily buried in the new sand. The water is good & clear...
