Whites Tree Frog - Looking very poorly

[Sunshine]

Here is a pic I found to show the paper towel as substrate. It should be enough to cover the bottom of the enclosure- maybe just two layers thick- as it will need to be changed when it gets soiled. I would wet the paper towels thoroughly and squeeze the excess water out.

I found a dusting powder that is available in the UK. It's also the only one I found and I don't know if it is any good but I figure it is worth a try.

Also, the cricket in the picture seems a bit big for your frog. I would try a smaller size. A good rule to go by would be the feeder should not be bigger than the distance between the frog's eyes. Is there a place around there that sells butterworms? They are high in fat and calcium and frogs seem to love them. I would also get some unflavored pedialyte and let him soak in it to get some electrolytes and energy back. I think the ratio is 1 part pedialyte to 10 parts dechlorinated water. Try the soak and then see if he will eat for you.
