Pacman not eating

I am trying to feed him night crawlers but he isn't having it, what should I do? Do I need to get crickets and try them? He is in QT right now going through chytrid treatment.

My pacman wont eat crawlers. It tears up crickets and pinkies though...

I was hoping to get it on a diet of crawlers because of how cheap they are but that's not happenin.
