I agree that Pangea is the best crestie food available. It's the only one I'll feed.

Judging from the size of the gecko compared to the thumb, it's still a juvie, and juvies in between growth spurts and males tend to be on the thin side. It's also common to see ribs on a crestie's sides when they're standing somewhat curved. The crestie's weight looks good to me. Many people overfeed their cresties, and overweight is not good, either. Here's a link to a good video on the subject. FWIW, I have a few geckos that JB, who made this video, bred and sold to me. https://www.youtube.com/watch?v=Mw2IQxToh_8
