Answer
Kathy, I think what has happened is you suffered fom I am not sure what happened. Most detfinately try again. Use the formula maximum 1 fish per sq. foot. Try the maximum goldfish until you see what happens. Get feeder goldfish from the pet store. If thry survive get your Koi. 50 cents is much better than $16.00.
