I recently got some baby Australian white tree frogs and one of them is doing great, hopping around and eating just fine. The other isn't doing very well, he seems to be having trouble hopping and using his back legs, moving in general. I've already fallen in love with them and don't know what to do. I'm not sure if it's the habitat or something else I'm doing. I have read. Several books on them and have the habitat set up like they say too, right temp and humidity. Please help me, I love my frogs and don't want to lose them.
