Got bitten by the Koi bug and made a very small pond outside. (1.8 x1.8 x 0.5), I am rather restricted for space. 13 Koi is what i have inside, ranging from 10cm to 2 x 60cm beasts. (Yea I know they are actually small, but for me they are beasts)
I have the Koi purely for their beauty, and like to watch them.
Now my question, would a fishtank inside be OK to house a few small ones? Or are they purely outside fish?
Thanks for a VERY informative forum.
