Agreed great give away presents or gifts to beginner hobbyist.I wonder at what age the barbels on koi become visible.
I'm not even sure if all Koi X goldfish have barbels.
Definately interesting to see how they develop.
Instead of culling the runts you could potentially give them away. i'm sure many children of friends and family would be happy to receive a free goldfish. I would be haha
When I was a kid I had goldfish , kids don't really care much about the conformity of their type they will love them.
And no koi x golds don't have barbels
