It all depends on the size of the feeders and how
much you feed. I would say 5 crickets or dubias every day would be fine. Skipping a day one or twice a week would also be a good thing.
I would never feed mealworms-they are just not a good feeder and not worth it. They area bit of an impaction danger. Superworms are a much better feeder.
thanks for the info . i was about to feed him couple. how many superworm or hornworm can o give him a week . i know that usually u can only give him 1 hornworm a month but not sure about that .
