There are plenty of feeders you can get shipped if you don't mind the extra costs. Crickets, roaches, phoenix worms, butterworms, silkworms, hornworms mealworms, beetles, etc. I wouldn't feed a frog - any frog - the same kind of earthworms exclusively (my experience is mostly with tree frogs and a few "true frog" species). If this is a problem, then maybe a frog isn't the best idea. My advice is always, if you can't be sure that you will be able to tend to every aspect of the animal's needs, do not bring it home.
