I feed my crickets orange cubes (flukers), fish flakes and collard greens and other veggies. My Vet says Collard greens is very nutritious to give to crickets. I also dust the crickets 3 times a month with Reptocal , But my frogs are older 8 and 5. I do feed my older one, a frozen pinkie mouse covered in a vitamin booster my vet gave me once a month. I don't suggest feeding them pinkie mice. My vet had me do this since he kept getting these really nasty infections. You can also give your frogs earthworms. My frogs totaly freaked out and would not eat them.
