What Bill Cody said about habitat plus size of pond. There are smaller lakes like 15-20 acres near me in NY that have CP, SmB, lmb, bg, GSF, YP, Shiners, catfish, pumpkinseedand rockbass and probably others I forgot, LOL. I think they all coexist because of hiding places, weeds and the pond is large enough. I think a 1/2 acre pond, even with weeds to hide in, LMB will beat down CP young and recruitment will be Nil and they will eventually die out. I think it is the old adage, if you want SmB, start with them and you can always add LMB later if you want to switch, but tough to go the other way. Start with CP and can add single sex LMB later if you want. And then can always add both sexes LMB later if CP seem out of control.
