Three months ago I adopted a community of animals. It contained a Basilisk, Cuban Tree Frogs, and 3 Whites Tree Frogs. When I brought the animals home I separated all the species. The Whites Tree Frogs were very skinny but other wise seemed healthy. Today I noticed a lesion like spot on one of those frogs. I will be taking him to the vet ASAP. Unfortunately the only exotic vet who will look at frogs seems less knowledgeable then the people on this website. I was wondering if any of you have had a frog with this same problem, or have a suggestion on how to treat him.

The pictures I am attaching are the following: 1 "Skinny" when I brought him home for the first time. 2. What Skinny looks like now. 3. His sore.
