Wow, if those pics are with your "crap phone" you have one heck of a good phone! Mine take great pics if the object is still, but never on moving objects. They are soo cute!
So, if you just started your pond dig 2 months ago, are you saying that you have it done, koi are in the pond, they spawned already and you have these fry??? Or, did you already have a pond, and are making it bigger? That's crazy if you got a new pond and koi spawning in 2 months time! I'm ultra impressed! How about some pics of your pond?
It's much easier to photograph a pond than it is the fry. I saw the other fish, but not the whole pond, I don't think. Good luck with your infants!
Oh and I went back and looked at your pics of the parents and see some of your pond set up! That's really neat how you made that overhang with what looks like driftwood on the one side of the pond. I didn't even look at the pond earlier, just was focusing on the parents. Thought it was funny that you called the female the "dude". LOL
