So last weekend I came across a female Gray Treefrog crossing a country road late at night. I was just going to take a photo of her until I (a) noticed it was a female and (b) saw that she was pretty round in the abdominal area. This prompted me to hang on to her and find a male (which I did about 30 minutes later at a nearby pond where he and a bunch of other males were calling like fiends). So now I have a pair of Gray Treefrogs.
It has taken me several days to get everything together but they are now in a small Exoterra habitat. Instead of having substrate, the bottom of the vivarium is water. There is a large piece of driftwood with multiple emergent Java ferns growing out of it, and this takes at least 1/3 of the area of the vivarium bottom - it also is too big too be submerged. I've got various perches/large pieces of wood from dead trees in their habitat and two artificial trailing plants that come with the Exoterra kit. I've also rigged up a rain system using a water pump and a transparent tray with lots of holes in it suspended at the ceiling of the tank - it works rather well.
This is a real experiment for me because I've never kept treefrogs before. So far I've been very pleasantly surprised by the female - she got over her nerves very quickly. She will watch me from the vivarium and will take waxworms from forceps (she eats and eats and eats). The male, on the other hand, is a little shy and he has yet to eat for me. Any tips, please, as to how I can get him to eat something/gain his confidence? He hasn't called for me since bringing him home.
