Hello, I'm new to the Forum and I have a problem.

Sadly, one of my brothers juvenile red eyed tree frog died and I tried to research the cause of death, but found nothing.
The best description he could give me was that his legs were brown and dry. Hopefully, I could find an answer here, any help will be greatly appreciated.
Thank You.
