I was at a local fish market that sold live steamer clams. I thought, "What the hell", and bought a 1/2 a pound and dumped them in my tank. No octo yet. Do these guys need special lighting like the exoctic clams? I doubt it cuz they luv to be under the sand. Has anybody got these guys to survive, or better yet, reproduce? this would be awsome if they do the nasty cuz it's feed my little octo when i decide to get one. Anybody have an exp. with this?
