Thats great to hear, I have decided that tilapia will be the way to go. but i am kinda worried about the blues surviving and making a mess. The pond was frozen over today and my temp read 40 degrees in the shallow end under the ice but It doesn't freeze every year. Takled to a local dealer and said that blues were illigal here and I needed to "use his niles" I am checking into that with wildlife to see .
