I have had worse mixes than that before, in smaller tanks, but with smaller fish. It's a tough one but we all learn something when that happens. Kinda unavoidable IMO. I think these threads are very informative for those lookign to mix cichlids. BTW, my male trimac beat the crap out of freddies and 'Escondidos' and some more if I would have let him. He is bad on plecos even. I always moved the fish before they got beat up too badly. I've always watched fish very closely when introducing them to new tanks, and even then they turn on each other when you aren't around.
