Hi, I have a 75g with a fx6 that has 3 corys, 2 guppies(I think certainly don't look like them), 1 golden wonder killi, 1 african butterfly, 1 bristlenose, 1 bolivian ram, 5 Buenos aires tetras, and 1 honey gourami. I want to know if there are any good cichlids for my tank or is it to full and stuff. Thx.
