I have a 220gal and I am looking to add a couple new fish. The current stock is 1 festae about 6", 2 green terrors 6-9", 2 jack dempsey 9", 1 pike cichlid 5" & a 4 line puicus cat. I would like to find a couple compatible south or central ciclids. I would like to get a color change up of maybe some orange or red. I was thinking maybe a texas red or even a severum? I don't want to add to much more of a Bio load so some thing around the same size as what I have already or smaller for a max size would be ideal. Thanks for any imput.
