I currently have a Polleni and 2 dats in a 30 and I want to move them into a 220 with 3 Flowerhorns and 2 Oscars. I'm not concerned about the oscars but I am a bit concerned about the flowerhorns. Does anyone have any thoughts on this? I feel 85% sure that it would be OK I just wanted to see what thoughts you guys would have. Thanks in advance!!!
