My young cyclura cornuta's terrarium

This is my 18 month cyclura cornuta's 75 gallon terrarium. I will transfer him to a larger enclosure soon probably outside. I have a reptisun 10.0 flourescent streching the entire length, a basking spot light that reaches about 105-110 degrees f and a full spectrum just for visual light. The bottom of the terrarium is lined with timothy hay. He also has a raised basking site. I feed him collard greens and mustard greens most of which I grow, dandelion greens, bokchoy and small amounts of kale. For veggies I offer him winter and acorn squash, home grown organic alfalfa sprouts and some other misc. veggies (carrots, stringbeans, peas etc.) As for fruits he is offered small amounts of mango, strawberry and banana. I supplement vitimin and calcium periodacally. He is 18 months old and roughly 22 inches STL.
