Alright, my current stock is a follows. 55G = 2 x male convicts, 8 Tiger Barbs, and one 2in Red Tail Black Shark (for bottom feeding). I am turning over 800GPH in this tank (2 x AC70's and 1 Penguin 200). My thought is to keep things as is, but wanted some opinions. I know that a couple of you suggested possibly throwing a Firemouth in the mix.
