I don't think they ever stopped breeding. http://www.ceratodus.com/index.htmlWell it looks like there's at least some breeding operations going on again if the super secret 2" AUL thread in the lungfish is any indication. Hopefully they've got them breeding reliably enough that costs might come down. It would be great if they'd get back into the US market, and seeing them readily bred would be incredible from a conservation standpoint
These breeders have been around for a long time. Just need to order a minimum amount of AULs. I don't remember how many but unless you are balling, you would need to make a group buy and split the cost. Not sure if the recent order was from these guys.
