I have them in my 5 ac. Pond for 4 years and they are 5-7 lb and haven�t spawned to my knowledge yet. The bull heads have on the other hand. So it�s probably a hit or miss thing. I have at least one ac of flooded creek bottom with trees. I have a friend with a 5/8 ac pond and his did spawn. Stocked the same time as mine and from the same supplier..... so who knows....
