He's 1 1/2years old. I've had him 4 months, adopted from another family. He hasn't eaten regularly since I adopted him and he's been very lazy (he doesn't like crickets, but I've been feeding him greens, and fruit which he eats a little of every few days,). After joining this website, I read about phoenix worms, ordered some and he has eaten them. Yesterday after eating, he did become very active, and yes, last week I did get a new UV light (I didn't know how old the one he came with was).
