I would pay $100-$200 for a captive propagated pink yuma. I would not sell any babies of that yuma for less. It seems that solid pink/red yumas from the ocean go for atleast that much, and many/most don't survive, so you've got a big edge because yours is healthy and a clone, so it'll definately be hardier than their wildcaught counterparts.
When you do sell, I would mention that it's a propagated clone, you should get more interest.
