Had them year before last.... They do breed like mad, but they did not make it thorugh the winter.... Not very large....
I wanted them for mosquito control... Also to fill out the pond.... I lost alot oif koi lately and I only have 3 left..... So, I was hoping to have more creatures out there... But, mainly for mosquito control.....
As for the koi I lost, I treated with Kordon Pond Ich and it has stopped the flashing as I believe it has killed off the chilodonella......
