this may be a very dumb question but....

I have several black fry. They are different than the others, much sleeker build, shy and very fast . They almost seem like completely different fish - whats the story?
thank you in advance.!

Probably "throw-backs", "reverts", or whatever you want to call them. Magoi-type fish that may maintain the wild coloration. Are they growing faster that the others? Were the parents matsuba?

they are about the same length but much narrower and sleeker. smaller heads. and they behave so differently - they are very shy, and fast I didnt even know i had 2 of them for over a month.
my adult koi are mutts - one male is almost all orange and the rest are splotchy with no distinctive patterns. (white, orange and black) I have so much greenery right now its hard to get pics.
thanks for the response!

Some of those splotchy sort of koi can throw about 95% wild-type offspring. The first koi spawn I ever reared was like that. I kept waiting for them to change color like goldfish - but of course they never did.

I had a few throwbacks last year too. Just a handfull, but several of them seem to lighten up to khaki tan/Olive in the right surroundings so they may just be darker chagoi.
