Well last night when lights came on for the frag tank I noticed my last clown of a mated pair had disappeared without a trace. The other disappeared a month or so ago the same way, but the cover was on the tank (BRS screen top). the cover was left off the tank, but I found no traces of the fish anywhere. Would it be possible for an acan or a rbta to eat the fish? the anemone is pretty small so I really don't think it could have but ya never know. Thanks
