I just wanted to update everyone. I have continued salt treatments, and all of the seven Acei are looking better. I will probably remove the other two males, but I'm trying to wait and see how the new dynamic works. I removed all previous decor and bought a ton of clay pots to replace the old decor, which alone helped aggression because all areas of the tank were equal and the three bullies were able to pick their own pots. Granted though, I also bought six Red Zebras of equal size and added them the instant I put the pots in the tank, so the one dominant male in that group could find his own pot. So far it would seem that the Zebras are the more docile critters in the tank, playing follow the leader everywhere. The Acei have been a bit nippy towards their tank-mates, but the aggression has let up considerably. The main Alpha Acei has definitely gotten better, since he has twelve things to chase. (I realize my tank is overcrowded, and I will upgrade tank size as the fish grow.)
