Hello, I believe my red eyed tree frog is sick. I've cleaned his terrarium out, and have laid out some paper towel. I did take a picture last night of him, and thought I would post a picture for you to see. The neon green spots started out small, and then started to turn out into splotches. He is still eating, and moves about in the his home but it is not normal for him to be sleeping on the floor. He did the night before manage to sleep on the wall instead of on the floor but he is back on the floor sleeping. I have had him for a at least 2 almost 3 years now and this is the first that anything like this has happened.

Any suggestions would be appreciated. Thanks!!
