i prefer this to the able. the aggressiveness of the gourami would depend actually on the fish itself. probably 1 male with 2 females is the safest. the male wouldnt be so hard on the females and the lowers the chance of the females ganging up on the male. i'd actually increase the no. of angels to around 2, or if possible 4. i feel that its better to have them in pairs (a personal opinion).1 x blue acara
1 x bristlenose
2-5 x dwarf gourami (apparently keeping them in larger numbers reduces aggression? if not change that to 2)
2 x blue/bolivian/gold ram
1 x angelfish (? not sure, would like something that shimmers like the other fish, but can't think of anything... I also don't want anything orange)
