The koi / comet fry are starting to come to the surface a little more. The tub has rainwater and chlorine-treated pond water - no untreated tap water. There is a UV filter running and an air-line with air stone. The water is slowly clearing and I hope to see more fry soon.
Second video for today. The 'steam train' you can hear is my barmy dog. I spotted one fry and another joined it for a little while.
I'm using koi food plus lots of dried mealworms, crushed to a fine powder. That will have to be OK until the stage 1,2, and 3 food arrives.
As you can probably guess, I'm totally winging it, I've never tried to bring-on the eggs the Koi have spawned before.
I only hope I get something right and I end up with a few new fish.
