I am more worried about a crappie explosion before the catfish get going, but I really was hoping so few added CC, BC, and RES in a pond full of forage would leave each other alone long enough to spawn. Planning to buy the smallest size fish available and hoping 10 of each will be enough to eventually pull off spawns for each species. If it looks like any of these are not doing that, I can always stock a few larger size individuals later.
