Ball Python Not Growing

[tttaylorrr]

I used to feed him once a week. I switched to every 5 days. He eats every time. Could there be an infection that is causing him not to grow? Its weird because he doesn't look skinny.

i would consider getting a fecal done. how long has he been at this weight? when was the last time you weighed him, at what was it? how long have you had him?
