If the babies are small, less than an inch in length, you can probably have
1 fish for each 2 gallons of water. They will grow. Typical growth in the
pond is about 8 to 10 inches per year in my zone 7 area, so in an aquarium,
being fed over the winter, I would expect them to grow at least double their
current size, with 4 times not being unreasonable growth. If you get 2
inches of koi per gallon, you will have to have some super filtration, or
you will work yourself to death doing daily water changes. As for size of
aquarium, I have seen people have koi in aquariums as small as 10 gallons,
but 20 or 50 is better.

I was considering buying some baby koi (or getting some from a friend
whos may be spawning soon) and wintering them in an aquarium. How

Scott, that aquarium is no where near big enough for 32 inches of koi.

I live in Ottawa, Ont and soon it will be winter. Actually, it felt
pretty
cold this morning. Anyways, My son has a friend with a large 65 gal.
aquarium for sale. It is 36 inches wide by 18 inches by 18 inches. My
thought was to bring the four koi (about 8 inches long each) in so
that I
could enjoy them throughout the winter. The goldfish would stay in the
pond
with the aerator and heater. I like the idea of seeing the koi but am
not
sure if I want to have to do a lot to maintain them. In the pond, I
wouldn't
have to do too much. Any thoughts?
