Hey Tim, I know what you mean about looking at your large aquarium, I have those thoughts too. But as I think about the food chain in a clear water environment I have to wonder. I am considering a shad and crawfish forage base to compliment my b-gill, and will be sure to start a good feeding program for the b-gill and cats! Do you think the addition of fatheads would be too much or is there such a thing when your talking "small" fish forage? B-gill,shad,crawdads,fatheads. Too much? Or managable?
