Dean, I begged them at Aquaristic to give me the piece that was in their little display tank and they wouldn't sell em any. Then when I returned some weeks later, it was gone! The guy said it got eaten!
It's probably dragon's breath.
It is very beautiful Dean.
You should get yourself a fry-saver or some other small containing to keep it isolated in your tank and hopefully it will grow.
If you want to get rid of it, I would happily visit and take it. The offer is still open.
