Ugh! As someone new to BP keeping (and hopefully breeding in a few years when my youngsters grow up), your post made me feel ill.

Unfortunately the best way to get this guy to drop the whole idea and move on to another "get rich quick" scheme - hopefully one that does not involve live animals - is to let him fail as hard and as fast as possible. This means withdrawing all help. If you don't want to publically out him, at least consider privately contacting the people he has purchased animals from so he finds it harder to purchase new animals. A breeder who cares about the health and welfare of the animals he sells will stop selling to the guy, and one in the biz strictly for the bucks will refuse to negotiate with him.

Considering what you've posted here I'm also surprised this guy hasn't blamed the sellers for sending him sick animals.

I feel sorry for his snakes. He's throwing away morphs that people like me would love to have.
