My only warning of Mangroves would be, like you stated earlier, there are not a lot of CB ones. And everyone I speak to about them says the same thing that WC almost always have severe parasitic infestations. Including the one I stumbled upon and bought. Other than that he was a fantastic snake! He ate wonderfully. And was always up for being handled. I also have a friend with a FWC and that is one of the sweetest colubrids I have come in contact with! But everything with animals is subjective, of course. Happy hunting for your next herp!
