With angels u could add severums, festivums, red head tapajos, loaches, coydoras etc.. Ur tank is big, so u won't have a problem. IMO rams r too small for a 210 g tank anyways. In my new 200g I have 2 green terrors, 1 texas, pair of convicts, 7 clown loaches, 1 BGK, 1 red tail shark and 1 clown knife (will be rehomed when gets too big) (all juvies) and I'm thinking of adding a few more fish.
