My pond is 30' round pond. I have 2 koi about 18" each. They stopped growing. The 2 youngsters were 9" last summer. It is my minnow breeding pond for feeding my bass pond. I had koi in there for five years before they spawned. I took all the koi i caught in a minnow trap to the local feed store to be sold. And now feed the minnows in the trap. Koi haven't spawned since. I have never seen them eat a minnow. They eat something at the edge of the pond, but I can't see what it is. Seems to be enough, and if not, let them eat minnows!
