the past week the rock anenome in my tank won't stop moving. he stayed in the same place for3 months (since we got him on the lr) but all of a sudden everynight he's off wandering. he moved down the rock, then to the back then to the top now he's on a completley different rock. is there any reason he might be doing this or is he just bored? :? also could he hurt any other life on the rock with all his moving? after last night the sponge that's on the rock he used to be on doesn't look great. we have those small, i think community, feather dusters and a tiny brittle star fish that he's practically sitting on. i didnt know anenomes could be such weinies!
