My 4"Jar took Food Sticks Pellet in two days and It only like Hard Pellets. Wont even swallow soft sticks. I would try FoodSticks and Crickets, Aro's Love crickets. I would starve and Offer Foating Pellet or Stuffed Sliced Market ShrimpOk, he is "new". For pellets, you can try soaking them in an additive such as garlic guard. It not only make the pellets more enticing for the Jar, but, it will also soften them up so that they will be more readily consumable for him. It is worth a try.
