I recently got a pacman frog about 16 days ago. His skin appears to be turning tan and brown around his face and back in some places from bright green. He is about 1-2 in. He was In about a 1 gallon terrarium at the pet store and is now in a 10. Temps day 77-84 night 76-82 humidity is about 50-80 some times 90. I have touched him a few times trying to dig him up to encourage eating but he is now eating and pooping. He is in a terrarium in my bed room. Is this stress or and infection?
