Just when I think I have a good stocking list prepared, something always seems to come up. Any way, I have a 220G that has been setup up as a reef tank now for 6 years. Currently the only inhabitants are a flame angel and hippo tang. I'm going to switch to FOWLR and need to add a few more inhabitants. I'm going to keep an eye out on the tang with the first fish I add, and check to see wether or not he is going to be aggressive. If he does pick on any fish added, I will turn him back into the fish store, they have already confirmed they can use him. Currently he doesn't pay the flame angel much attention, so I'm hoping everything will be fine with him. So I would like to add a pair of percula clowns, a goby and shrimp pair, and an orchid dottyback. My concern is how the dottyback will behave around the clowns and goby. I have read where they can get aggressive to other smaller fish, but most people seem to add other similiar fish. Not sure if the clowns and goby would count as being similiar. Any opinions on how you think this would work out? Thanks.
