I guess I have BG and HBG in the pond. I do notice little BG growing as well(2-3 inches). But I know for a fact that I have never stocked BG in there before. Will this hurt the HBG population? This has just happened this year cause I have noticed the LMB to put some weight on.

Take someone new fishing at your pond. They'll be hooked forever.
