Our WTF is not looking well and we are not sure what's wrong with him. When we got him 5 months ago he was a lovely classic jade colour at night and that dull brown during the day. Recently however, he's been constantly brown and just not 'looking' right, and more worryingly within the last week, he seems to have lost the ability to climb very well, sliding down surfaces he used to cling fine to, and is generally more clumsy.

There are other frogs in the same 45x45x60mm exo-terra vivarium, a false tomato frog called Gary, which was bought at the same time from a reputable shop (owned by a PHD-in-frogs bearing man) so I presume HE is not toxic. About 2 months ago we procured a Grey Tree Frog we named Squarepusher, and two weeks ago we bought two Common Tree Frogs called Nietzsche and Shylock. We're prepared for the possibility that the new frogs may be toxic to the WTF, and would appreciate if anyone could shed light on his debilitation.

Thanks in advance,
