That cricket looks like a little more then your aro should have to handle. Do you feed the cricket with hind legs on? IDK if they would be sharp enough to puncture the little aro's internals or not.
Cute, but get ready to buy tons of crickets. It would be hard to train them onto pellets when they are older once they are addicted to crickets. If you plan on pellets as staple, only give crickets as a treat now.
