Hi there! Welcome and congrats on the new frog.
I'm afraid you're going to have to feed either crickets or roaches. Even though there are other things they'll eat and it's good to have a variety, crickets or roaches will be the staple. Mealworms and superworms are hard to digest, and wax worms are fatty. All of these worms should only be fed occasionally. Mice should rarely, if ever, be given.
You can get use to crickets easily. It'll be fun.
What's your setup like? Any other questions?
