I've been reading the posting about the choice between crabs and an LMB. That made me wonder if an LMB would be good for my tank if I put the sun coral in. The sun coral has a nice crop of long green algae from when it was being nursed back to health and was purposely overfed. Well the coral is doing wonderfully but where it had retracted the algae took the opportunity to move in! Would it be safe to put in the LMB and would he eat the green algae and not harm the coral?
