So far the deformities I’m seeing wouldn’t. One has a bent spine and another has only the top half of its tailfin.Most of your fry are going to have single tails, and deformities can enhance value sometimes.
It is said that there are only 1 good fish in every goldfish spawn (old Asian saying).
Don't be surprised if they don't show good color for months either.
I think that saying will hold true for this spawn, if I’m lucky! Maybe one will be worth keeping or selling. I’m feeling discouraged, but maybe over the coming months they will surprise me.
