Just to add my experience to this thread. I built a one acre puddle, max depth of 14 feet. Stocked FHM, SFS, BNM, Crayfish, YP, GSH, RES, RESxBG, WE, HSB and SMB. Stocked at different times and the WE and HSB ladder stocked. Every species is doing well, length and weight....expect for the WE. Length-wise they're fine. But they're skinny and sickly looking. So we are actively removing them and considering a different route without them. Just my experience. Congrats to those who successfully grew them in small ponds. I'm jealous!!
