look at the care sheet and mimick it. Very very good information. Also since you have a viv...you also might want to put something around the 3 sides of it to make him feel more secure. If you have a UTH...make sure that you have a thermostat controlling it. This is super important as some places will tell you that you will not need it. YOU DO!!

Like Kaorte stated...it looks like an 09 to me as well. If he is stressed still after your changes with 2 hides etc. you might also want to add more plants or something to fill up the tank. Also make sure you don't leave that light on all the time. They don't need it.

OK one more thing.....how often are you feeding him? He could just be hungry as well. Also balls are more active at night and tend to be in hides all day long.

Hope this helps!!
