Maybe if it is a really rare kind. The ones we have were about $20 each when little, but now after 4 years, all of them, especially Whale, who I think is the one having babies, are HUGE - about 18 inches long! We have 6 big koi and 4 pr 5 dark blue baby koi - we call them stealth because they are the same color as the pond water, and all you can see are their lips when they eat!
