scratch the question on the BC. I just read a post about them and the competition with the other small fish.
I am currently doing a 3 acre BC, CNBG, RES, CC, LMB pond. The BC from what I see is something I believe that can be done (becaue it has been), but I believe it will take work to manage closer to keep them from over populating. Here is a video you might find interesting.
