Looks like you are off to a great start you can also try worms they like them also .I would wait till all crickets are gone b4 adding any more also try wax worms .They eat mostly food items where they are found under rotten leaf and wood matter .That is where youll find the grubs , wax worms, and red worms, try those and he/she will thank you for it . Most of what I mentioned can be had at any fishing /bait store.
