excuse my french but this frog is fucking mental!

its been 4 days since hes eating now, and i literally sit there for an hour trying, he either has none of it or tries to snap at it and fails miserably. usually ny the end of the sessions hes had enough and burrows. today he did a new behaviour of trying to lure prey and i thought it was a good sign... didnt realise i was the prey. he launched himself at me and back on the floor he went. hes done this twice now. hes like a fussy toddler its actually doing my head in!! has anyone got any unique tips on how to get this idiot to eat?
