Hi, Sorry if this is a silly question but I rescued a small savannah monitor(very small SV length is only 4in or so) today that was "dumped" on my cousin (who thought it was a desert iguana). I own 2 iguanas but have no monitor experience at all and just went thru hours of "crash course" online and have him set up pretty well for the night. My one question is, somewhere i read that his inside mouth is suposed to be a healthy pink, well he just yawned and his mouth is definately black inside. He also seems to swollow very hard ocationally. Other than being dehydrated and taking a big drink when I got him settled, he is actively exploring his new surroundings and has no visible discharge or signs of illness.
Is this black inner mouth and swollowing pattern normal? he was previously in a filthy 20gal tall tank, with a dirt substrate full of morphing uneaten mealworms and crickets, with 2 green iguanas, 2 local lizards, and no real bottom heat source (he was cool and unresponsive when I removed him and has definately perked in the last few hours)and no water.
Any help would be greatly appreciated, so far ive found alot of info on habitat and feeding but very little on common ailments and thier symptoms.
Thanks
