We have a pond that has both goldfish and koi.  We started with goldfish and one of the babies turned out black then turned to orange.  Since then several have grown to a large size (for goldfish) and have remained black.  Now we are getting more that are remaining black.  They are shaped like a comet and do not have the bug eyes.  I know they are not koi but rather are a type of goldfish.  Do you have any idea what kind they are?  How  can we keep the black ones reproducing to get more black ones that will stay black through adulthood?

Thanks for any help you can give.

They're shaped like comets? So... they're simply black comets. ANY variety of goldfish can be black, not only moors (but it's only the black telescopes that can be correctly referred to as moors). The thing is that the black color usually is "sticking" better to a moor and they usually stay black their whole lives. Since they're born bronze, they turn more black over time. Sometimes they start turning golden/red after a few years though. But like mentioned, that's more common in other varieties.

If you want to breed only the black ones, choose one pair in particular that you think have the strongest black pigment, and that have stayed like this for the longest time and try having them lay eggs in a breeding mop in a large tank/separate pond. There's unfortunately no guarantee that these fish WILL turn out black for sure, but if you're lucky, most of them will d: And even if they're black when young, they may turn red or yellow as they age.

It sounds like a really lovely pond, please post some photos
