Yes, I hear some chams don't like the Phoenix worms. Mine happen to like them. My teenage Amilobe will run across the bottom of the cage if he spots one and pick them off quickly one by one. My other Sambava eats them right out of my hand. I think its wort it to buy a small amount of them at least to see if yours will eat them. They do take off and go straight to the floor, which is the most annoying thing about them.
