Bill I found this from a fish supplier who supplies a variety of native fish for aquarists. Here's the link.
HERE. Scroll down a good ways. They come in a lot of two and run $30. But if you notice all of his fish are expensive...he catches them all by hand/net. So I'm sure you could get them cheaper. He's a real nice guy. Maybe you could contact him and ask him if he knows anything about them. I'm sure he does.
