i want to have a pond that would be large enough to house lmb or crappie. if i get lmb it will be 1 and if i get crappie/ or bluegill it would be a small school that would be caugh/eaten if population is too big. want something small but large enough to house them, but that looks nice. dont have much flat land but trying to find something. oo and it has to be kidproof these little kids always run through our yard and dont want them to get hurt
