AWESOME food sources: B. Dubia roaches, and B. lateralis, common name's being dubias and red runners/turkistan roaches. They very nutritious, and dubias don't even look like roaches, just big beetles, but dubias get up to 2.5 inches adult size. Turkistan roaches only get about the same size of crickets. most animals love them too. About your crickets, you can wait and see if they eat em, or take em out. They generally don't harm the frogs, other than when they die and rot in the tank.
