TG4,
I found it very interesting what Harrell Arms said about red ear. I totally agree with him. I stocked several hundred in a larger pond and they basically disappeared whereas the CNBG prospered.
My original recommendation to you was to stock 50 red ear, up to 100 if desired and add HSB only if you remove CC's. If you remove 100 to 150 CC's, then 75 HSB should be just fine. However, as time goes forward, I would continue to remove all CC's that get to two pounds and above.
