Hmm tricky, perhaps try him on morio worms and see if he will take these? The more movement the better as it entices them!

In all honesty it sounds as though your set up is fine, although I would recommend leaving perhaps 2/3 crickets in, although they're jumpy at first they do settle and my pacmans eat them this way very happily!

Pacmans are quite hardy frogs so as long as he is still eating something then that's good, are you mist spraying his tank?
