sick iguana

I have recently had an iguana given to me he is ill i think dehydration so i would like to know what i can do for him he isnt moving around a lot cannot eat on his own so i am grinding up fruits and vegies and bottle feeding him is there anything else i can do?

You can make a hydration chamber for him. How big is he?

he is like 2 1/2 feet long

what are his temps and humidity? id say give him a bath and turn up the heat.
