Only just saw this thread!
I have two rays from paraguay one of which is in my avatar. Both now have fully mature claspers at around 8" disk.
I have spoken to the LFS where they came from and the difficulty is making up a decent order to come out of Paraguay. Apparently the high value fish just aren't available on anyone's lists. So even when the odd ray comes up it's too expensive to import most of the time. It's a shame as I'd love to see more of these rays in the hobby.
