Hi, the 10 gallon tank may feel to big for him and that's why he doesn't want to move. Some do ok in the 10 as a baby and others its just to much. Can you post a picture on photobucket or something so we can see how you have the enclosure setup? When you say he just sits there is he burying himself and not comeing up at night or is he literally just sitting there on top of the substrate? I have noticed from your threads that you have had to buy some new stuff and change some things up so he may just be having a harder time settling in because you are around the tank checking on him and correcting things. You may just need to give him some space. And im not saying this in a bad way so please don't take it that way but this one of the reasons people say to always do some homework and get the enclosure to perfect conditions before you bring your new frog home. And again please don't take that the wrong way because I know some petstores and stuff tell you the absolute worst info on care and then we are stuck trying to fix things for days afterwards to make our froggies feel better. But if you could get a picture of him and the enclosure that would help a lot.
