My 75 Gallon (48"x18"x20") is looking pretty empty even though I know it's plenty stocked bioload wise. Right now it holds 6 Giant Danios (3") which I'm debating getting rid of or not, 1 Yellow Bullhead (7"), 1 Gibbiceps Pleco (6"), and 1 Striped Raphael Cat (3.25"). I've been seining a lot of small Black Crappies (around 1") at my local lake lately and I'm thinking I might take one home with maybe a bluegill or two as well. I know I'd have to do more WCs but that's no problem. Also don't worry about the bullhead eating small fish, he's a wimp, didn't touch 0.5" cichlid fry when they were in the tank. What do you guys think, good fish to keep?
