Right now my 55g is overfull with a strange mix as I get my 125g all together. I have 2 parrots, around 3.5", several peacocks (4 4 females, 3 males, all grown), 3 sevs (2 are babies), 8" BGK, and some cories. The parrots actually hold their own, and will circle pre-lip locking with the OB peacock and the baby severums. Never fights, just the boys struttin' their stuff. It IS TEMPORARY, and I don't know that I would keep Africans with Parrots long term as they are more peaceful/quiet as has already been mentioned. They've been like this for two months now.
