I would not put any more fish in your 55 wait till u get some big tanks the bp's and smaller cichlids are cool in a 55 but the o's will need more room so when u take back the o's get some fm,gt,covict jewels,ba,sevrems stuff like that will do well in a 55.lol

I know what I am doing with the Oscars, have no plans on taking them back TYVM
As for the fish you listed, several of those will need larger tanks as they mature also.
