Two days isn't much time. I'd wait him out a bit, keep offering the crickets. Force feeding him may also stress him out and put him off food if he was not eating simply because he wasn't hungry enough and could be stubborn about it.
You are hardly past the point of no return. At most he'll likely hold out fpr a bit during live feeds but keep offering and it'll click that those juicy worms were a chef's special. Back to ala carte.
so if i just hold back from waxworms and offer crickets/roaches
he will be fine right? may be stubborn, forcefeeding is bad, but if i doesnt take them for along time i will have to..
so he will be fine and i just dont need to feed him waxworms for along time so he relizes they where not a main feed right?
