Can I mix koi with goldfish?

Absolutely! Both koi and goldfish are very docile creatures and will not harm each other in a pond or aquarium.

    I was told that Koi and Goldfish do not mix. That the Koi fish goes after the goldfish and bites and hurts the goldfish? This was in an article on line. so I can purchase goldfish and put in my aquarium with my 4 koi fish?
    What kind of golfish? Thanks, Robert.
