I forgot to mention that the Tilapia will die off most likely in November @ my place. The pond is also heavily stocked with cnbg and res and I do get bitten every once in a while when swimming. but it is more of a shock when they bite, there is no pain at all. So I would not worry about it. I have kids swim in the pond with no problems at all. I just have to keep an eye out for any gators that might someday might show up
