Koi babies vs goldfish babies bs guppie babies???

[Abby]

Does anyone have a specific helpful link, photo, or description to help differentiate between the 3? How big do they have to be to tell the difference? Are there any distinguishing features, characteristics, or behaviors between the 3? What’s the best view for determination… top view, side view, other? I have all three in my pond and a bunch o bebes but I have no idea how to determine which is which? Thanks in advance!

I don't know anything about guppies, but when I had both koi and goldfish in my pond I had to wait until the fry were large enough to have visible barbels in order to tell which one they were. But I'm hardly a fish expert...

Thank you so much! How big was that?

They had to be well over an inch before I could really tell. What helped was if I could get a nice clear picture of one & then I could zoom in on it. Some just seemed easier to see than others.
