Can't add anything to all this great information and guidance you have already got here! Except give him a nice pool to soak/swim in, they love the water. He will poo in it too so you will have to change it regularly! And they love being sprayed with fine warm mist.
Some "Old Fashioned" Quaker oats sprinkled now and then on his veggies/fruit is much appreciated (mine love it - they lick it up flake by flake).
I would love to see some pics of your baby red ig. Love iguanas.
There - I have added quite a bit anyway.
Congrats on your acquisition.
