    Just discovered this web page. Great info.

    I too have had goldfish since I was 10 or so ( now 62) they never lived long until I established a small 200 gal pond in 1975 (fish wintered inside). This pond became home for my 2 koi about 18 years ago, again they were wintered inside. This year I installed a 1500 gal pond for my (2) 20″ koi and 7 goldfish ( ancestors of some of the original)

    Thanks again

    Doug S.
