Hello and welcome to frog forum!!

Daybr4ke is right, your frog still has some growing to do!
Stay away from superworms, they're hard to digest.

I think your pacman is a fantasy?? (cross between Ceratophrys Cranwelli and Ceratophrys Cornuta) someone correct me if I'm wrong

Also your frog is not overweight. A good way to tell is that he should be just as wide as he is long

anyways welcome to the forum (also you should post some pics of your boa )
