I have a problem with my White's Tree Frog. For a little while now he has been kind of lethargic during the night. Also, for a few feedings he hasn't eaten more than a couple crickets. Currently he sits in his water or in a corner on the ground during the day, not up in the corner under his light like he used to, and he isn't as vocal as he used to be. He has been a dark brown for a while now - he used to stay at a pretty constant green/brown.
His inclosure is a 10 gallon fish tank with: a plastic plant, 15 watt day bulb, pine substrate, and water dish. He has no night bulb and every time I feed him I use a calcium dust. Please, anyone who can help, please tell me what to do.

i would take him to a veterinarian. My white's was showing signs of sickness a while bacl (not eating and stuff) and it turns out he had a worm infestation. I'm not saying that's wut's wrong with ur's though. Take it to a vet, and when you get it all fixed back into a healthy frog. Get it a bigger tank, . most white's need a larger, taller tank. Get at least a 20 gallon tall tank. How big is it? what is the tank temperature? humidity? night temperature? oh AND BTW, pine is not good at all for any herps, it contains bad fumes and it's sap is not good either. I would change that ASAP! That is probably what's wrong with him, but take it to a vet and make sure.

Well for one your tank is pretty small and your substrate is toxic. You may be giving him too much calcium and not enough vitamins too. Since you don't have a nocturnal heat source its possible the cage is too cold also. Accurate temperature and humidity readings would help figure out what's wrong with him though.
