I am not really familiar with many of the bluegills out there but just know that they can become a real problem. I had chosen the RES and HBG after reading numerous article (mainly on here) regarding the potential for large size and the benefits of RES for controlling the crustaceans which in turn control the parasitic worms and grubs. Also the fact that they do not reproduce quickly seemed like a big plus for not getting out of hand. I had planned on supplemental stocking of these along with HSB from time to time to keep them going. Knowing what I would like to do with my pond is their something else you would put in there in place of these? Also I love your idea of smallmouth bass in my pond but will they do well? I had not planned on supplemental feeding but will look into it to see if it is something I can afford.
