Am I feeding him enough? Is it a him?

[Stumpy]

Your frog is 4+ months old? It seems very small for that age but looks really young. I'd start upping the amount you feed it. The head in relation to the body is good but it needs to grow more to recognize the sex. My pixie is younger then yours and seems a lot bigger.

He was born in july ,and purchased by me on july 15th. I have measured him ,and he is over 3 inches. Here are some more pics.
