thumb tostocking fish. Usually the response is 1,000 for the first koi and
100
gallons for each additional koi. One has to wonder why the first koi
ishogging up 1,000 gallons while each additional koi needs only 100 to
behappy. What is needed is some more pictures, and "vitals" of full grown
koi. People don't realize just how big a koi gets, they are large animals.

I have 14 koi that range in size from 5 inces...last years babies....to over 25
inches actually I think 2 are closer to 30 inches both females and spawnig for
the last 2 years....about 6 years old. Actually there are only 3 babies....the
rest of the fish are all over 18 inches. I think if you followed the rule and
had 10 koi that would be about 5 to many for a 2,000 gallon pond. Befor the
heron visited last year I had 19 koi in 15.000 gallons. I do not run good
filters like every one else, but I still think they deserve the room....sort of
like keeping a dog on a chain in a small yard....they deserve better, they are
pets after all Jerri
