One week out shouldn't be anything to worry about poop wise IF your frog is acting normally. What is your lighting schedule? It should be 12 hrs on and 12 hrs off. I'd say get that heat bumped up... did you mean room temperature as in the room he is in vs the heat inside the tank? 21C (appx 69+F) is too low for a constant temperature in the tank, 26C (appx 78+F) is better, but it sounds to me like maybe he could be having some digestive issues with the cooler temps, try for 73-75F (appx 23-24C) at night and 80-85F (appx 26-29C) during the day. I would also get a fecal test run on him next time he produces poop. One thing that might help is to give him a warm honey bath: 3 to 4 drops of pure natural honey (not a cornsyrup-honey sauce) per 8 oz of dechlorinated water, just barely warm to the touch on your wrist. Leave him soaking in that (in a container he can't get out of, but do not leave him unattended!) for appx 20 minutes, then give him a tepid bath of water without the honey to clean off. That usually produces a poo either while they are soaking or within a day or two.

It would help if you could read this thread and then answer the questions so folks have some better ideas of what could be happening and how to help http://www.frogforum.net/tree-frogs/...enclosure.html Thanks.

Hope your little guy gets back on track soon!
