Hi,
On Saturday Dec 31, my daughter bought two Green Tree Frogs, which she had last year but died (not from disease). The tank is a 30 gal, with coconut/bark substrate, large water dish and heating from a lamp on top. All accessories in tank were cleaned with mild bleach solution the week before, and the top layer of substrate removed and new put on top. I wet the surface of the substrate and the humidity was at about 60 %. After putting the frogs in, we noticed that one tried to dig down, but later they both hid under the log. I noticed the temperature in the tank was low about 65 deg F. I put a heat pad under the tank on one side and moved the lamp into the tank (also noticed my daughter's bedroom was cold, and opened the heat register). At night put in a night bulb to keep the heat up to about 72 on the cold side. Since then both frogs have disappeared. I noticed humidity down, so I added water to the substrate. There are crickets running around seem to be less in number, but unsure.
Are the frogs okay? Should we be concerned?
Thanks
