I guess I should add my two cents, if you are not a big catfish guy, then don't put them in. They will certainly compete with your other predators for food down the road. Which is one of the biggest problems I experience. Bass won't stunt if you harvest both bass and bluegills out of your pond. The whole idea behind stocking a pond is to harvest. Catch and release only works the first few years. You won't have to worry about your bluegills stunting, if you add HSB. They are an aggressive fish and fun to catch. Also, people stock HBG, because they will most definitely grow at a faster rate than your BG, reason being their aggressive nature. Now, in the long term, your largest sunfish will be the Redear sunfish, with your BG & HBG being about the same.
I hope this clears some things up!
