New 55 gal Tank... Aggression HELP!!!

theres a lot of different fish, with different temperments in there. throw on top, alot of different sizes.

there's gonna be a sorting out period, hopefully everyone will make it through. all i can sudgest is clean water, lots of hiding spots, and stop at 20 fish. if one particular fish has too much fight in them, maybe consider moving that fish, to somebody elses tank.

are the new fish, the ones taking the beating. that would make sense, and part of the sorting out process.

About 10 years ago I was heavily into African Cichlids... Well some what... I had about 4 tanks going I didn't know much but I learned as I went on..... the hard way... Learning what fish I liked... what fish I didn't like.... Then I had a daughter and life changed and I stopped my hobby ....Well fast forward about 11 years and last weekend I got back in the game.... and I moved very fast. I knew what I wanted and I got that, but I'm struggling with aggression in my tank. I have predominately all male peacocks varying from 2-5"...I currently have about 20 in the tank.... 10 of them are a little over and inch........ I will post pics...any suggestions would help..... The OB Peacock and the Red Empress run the tank.... and are being real butt heads if you know what I mean.... I purchased some really nice fish at the swap yesterday and want to see them make it. The Venustas and the two Jakes have been taking a beating.... So any advice is appreciated.

Thanks,
Bill
