Iguana not growing.

[RandyRhoads]

I bought him about 6 months ago, and he's still tiny. I have a two bulb hood with reptimed uv lights. His diet consists of a combination of squash, peas, romaine lettuce, straberries, collard greens, and bannanas. I mist his enclosure every morning keeping it nice and steamy. I used blue iguana calcium supplements up until a month ago. I know he should be growing rapidly, why is he not growing at all?

The last 2 are of my adults (who is doing great) sunning cage.
