Do Bearded Dragons Need Live Food?

Yes, they do.

Live food is high in proteins, vitamins, and other lizard-
friendly nutrients. Feeding exclusively live food to your beardie is not
necessary. However, a live insect diet is helpful and healthy for your
lizard pet. If you choose not to feed your dragon live food, over time it
will lose the natural instinct to hunt its food and become lazy. Hunting is
a good form of exercise for bearded dragons.

Dubia roaches are the best source for live food due to their availability
and affordability, and your beardie will love them. Ideally you should
always use live feeders in your dragon’s diet.
