I have not seen one of my green tree frogs in over 48 hours. I have 2 in basically a 18 x 18 x 18 ExoTerra setup (true aquarium but similar size) and they usually hang out on top of the background. My bigger one, who has called a few times, always is the first to come out and eat crickets. My smaller one is a bit more shy and waits a while. I *think* the only one I've seen is the smaller one and I haven't heard calling in a few days.
There's three options that I see: 1) it's hiding; 2) it's escaped -- not sure if that's possible); or 3) it's dead. I fear it's dead. When should I take some things out of their terrarium to look for it? I've looked around decorations / hiding places, but haven't seen anything.
The other one is really just hanging out on the top of the background and shows little interest in crickets.
Thanks for any advice/comments.
