Lol, none of the animals from underground reptiles are CBB. They've told me their mangroves are CBB despite the fact there is virtually no one working with the indicus complex here in the states.

As was stated above, if you still have questions on sav care, I would recommend keeping up with him and learning about him. Once you've had him for awhile (5+ years), and feel comfortable with your amount of knowledge then is the time to possibly look at adding another varanid.
