Hi! I'm concerned about my AFT Bailey. He is the most gentle, cuddly little guy...until recently. He has hissed and snapped a bit lately, which is very uncharacteristic. Also, he keeps making a little noise that I'm guessing is a sneeze. Then tonight he started doing this weird thing where he opens his mouth wide and swallows. He does it a few times then stops, then he does it again later. Is my baby sick?! His temps are 78 to 94, 91 on the warm spot. Viv is 18 x 18 x 12. Moist hide, warm hide & cool hide. Eats dubias. I've had him for 2 months.
