Thank you for your interest and response.
I do not want cull them just yet, because I want them to practice.
And now I do not have for them too much time because I do home repair when I finish i'm moving.
My plan is this:
1. Do not bring a pair for spawning again, the above written reasons.
2 Feed the babies, let them grow for the time being.
3. When I move, make a selection.
4. For those with defect I wanna practice shipping.
Pack them in different ways, to check on the water and their condition after two days.
I myself do not like when someone sends me a fish and I recive them in smelly bad water, full of nitrates, poor condition, frozen.
I would like everything to be the best and I don't wont to sacrifice those nice.
I would do it best, then cull those with defects.
I know I have to do it, because I'm not going to sell the fish, which I would not want to have in mine aquarium.
As Elliot wrote, probably it was my fault that some of them have defect fins because they had too soft and too acid water when they batch.
I promise that next time will be better.
