Wes (Fugupuff is his handle) is a vendor in the marketplace under Rare Fish. He has some right now. 1 of only 2 sources I've ever seen offer them.....
They are VERY small right now, and very timid. Not something you want to just toss in with other fish, they'd need to be grown out for a while......
What kind of info are you looking for? I've got pretty limited experience with Polyuranandon as I haven't had mine long, but have kept eels for many years.
