I've heard multiple answers... some say a foot, some say 2 feet, others say they get as big as koi or carp.... I have a 9" one i plan on putting in a 210 gallon soon, and i'm curious how big this bugger will get.
How big do shubunkin goldfish get?

About a foot, a little over with good genetics and good conditions, 18" if you get really lucky. Definitely not as big as koi, though.
