They can be trained to eat frozen foods. Not always an easy thing to do though, from what I've read. And I'm pretty sure they've been captive bred.
Matt Pedersen wrote an informative article about weaning them, IIRC, a few years back. That said, I don't ever recall seeing them for sale of his website.
Definitely a fish that I'd be willing to let munch away if I had a large enough tank filled with Millie colonies.
I guess I will keep looking around for more information on captive bred ones. :reading:
