Here are the fish in my green tank. I'll let them overwinter in there. No fish have been culled. They color out so much better outdoors.
There are a few Sanke and a bekko that are promising
Some decent ones! Are ya gonna cull some time though???
Here are the remaining fish in my green tank. Fish from the 5/10/2020 spawn now range from 2" - 13". I'll grow out the 13" one just for fun, currently a pond grade kohaku.

This is the largest of the 5/10/2020 spawn (13-15") and one of her siblings in the top right corner. A month ago she was pure white so we will see what happens.
Very nice - thanks for posting an update. I have really enjoyed following your posts! It sure seems like you're having fun and making some nice fish along the way.
I don't recall reading about how you manage the water quality in the indoor aquarium. Can you share with us how you manage to keep good water quality with such high fry densities?
I generally have one tenth the recommended volume for a commercial canister filter. So for a 40 gallon aquarium I will use a canister filter(s) rated for a 400 gallon aquarium. If the fish are getting large I add a moving bed filter up to the volume of the tank. This eliminates any ammonia issues, regardless of how much I feed. A side benefit is that I can often go 4-6 months without cleaning the filters. For Koi I monitor nitrates and do water changes as necessary, other pond fish are not nearly as sensitive.
