POPPING sounds?

somtimes i hear popping sound when i handle my male rtb. I dont hear it when he is in the cage. I tought ir was an ri but there are no bubbles or wheezing. Is it just his stomach acids or his back popping???

Temps.
hot side ground=88-92
hot side air=82-85
cool side=80-83
cool side ground=78-80

P.S. In the past 2 weeks when i changed my my tub the humidity has been above 70% about 90 percent of the time. I drilled som more holes in the sides to see if it helps. could the humidity be a problem????

I think sometimes when they're twisted around your hand or what not their scales may get caught on something and they make that sound. I don't think its anything to worry about unless the noises are comin' from its mouth but you already said they aren't.

yea when i put my ear around on his body when he is moving threw my hand i cane hear it. But i guess its nothing to worry about.
