For a 3 1/2 yr old basking temp is too hot- older dragons do not like it that hot 95-100-- temp should be taken w/ a digital probe thermometer- I would feed regular water- unless it's winter where you are he should not be going into brumation-- what are you using for a UVB?At 3 12 years that is to hot maybe drop it to 95F but i am a new person but you found the place for help
