I would separate him from you other reptiles, always quarantine new additions.

Dawn soap and baths will not get rid of the mites, you need to get a can of Prevent a Mite: http://www.pro-products.com/index.ph...d=53&Itemid=59 and do as the instructions say.

Also is your UTH regulated with a thermostat/dimmer/rheostat? How are you measuring hot and cold side temps?

But besides all that...contact the person you got the BP from. See if they'll help you out with the mite issues, since you only got him today.
