Well I fed my octo for the first time last night. The first tiny fiddler made it into a hole in the rocks and the second one got nailed. This morning I found both carapaces lying in the sand under the rocks. What do you think would be the best janitor to keep the area under the rocks from looking like a cemetery? I might try hermit crabs bu they'll probably get added to the graveyard before they can clean it up. I think the best thing would be a small brittle star or two. Not the green serpent stars though. I'm not at the point of having foot long bristtle worms in my tank(like some of you ) just a couple tiny ones in the rock. What do you guys think???
