In my experience, people will pay for something they like/want, regardless of how the fins look. So if people are willing to spend $5 per fish + $15/$35 shipping for these fish, then she should go for it at that price. At least it finds the fish a home.
But in the future if the OP wants to find homes for more than a couple I would suggest a little research in fin types and combining them and what it takes :) If this was a spawn to help get the OP some experience in breeding, then that's fine - but in the future I would look into how to breed certain types, and what to breed to :) That way it will be much easier to find them homes to the people who are willing to spend all that money on a fish :)
As Chard showed - you will get a lot of sloppy fins and for color you will most likely get all blues with red wash.. basically be pet fish so the $5 would be the most I would charge for them to be honest.. which is fine, like I said, if someone really wants one they will pay it :)
