You can feed your bearded dragon occasionally with fruits like watermelon. You can also feed them with basil, rosemary, cilantro, thyme, and tarragon. However, common bugs and insects are even better such as earthworms, cockroaches, silkworms, crickets, and roaches. The most popular feeder is the cricket and Dubai roaches. Another pet owner prefers crickets because the roaches don’t smell good.
