I just purchased some Green Tree Frogs, and placed them in my old vivarium I had my Gray Tree Frogs in, cleaned it out before hand with dechlorified hot water, but didn't replace the log, background, plastic plant, nor the basking pool. I thought washing them would be good enough, but I don't know now. The new frogs have been hiding, with both of them now hiding in a hole within the log. They didn't want to eat (hand fed with tweezers), and they haven't used the basking pool. I don't know if there are any specific problems, but I'm worried about my new little guys. I'm gonna try putting the crickets in the tank tonight, but can anyone recommend whether I should replace everything inside? I'd rather not if I don't have to (for sentimental and financial reasons), but I want my frogs to be happy and comfy .
