So I got my new male lesser today. I made sure his terrarium was set up properly and put him in it after a small power struggle (he only wanted to cling to me) once he was in it he only moved around on top of the furnishings in the tank instead of directly on the substrate, which is coconut/aspen mixed.

My question is, once he got to the water bowl he drank some then dunked his head completely underwater twice in a row.He became quite irritated when aspen stuck to his face and proceeded to rub it off on the edge of the water bowl. He also yawned several times. I haven't read any threads like this, anyone heard of it?
