I have had 2 White's tree frogs for 3 years now. In the last two
months one of my frogs has been acting strange. He no longer takes
food from me when I try to hand feed, and I haven't seen him chase or
eat any crickets that I let loose in his terrarium. Today I noticed
that he was shedding and had some of his skin caught in his mouth as
he frequently does, but when I pulled the skin out of his mouth
instead of the normal white-grayish color, it was bright yellow. Is
anyone familiar with this or no what could be causing it?
