I highly recommend feeding Dubia roaches. Crickets and mealworms are my last choice for feeders because they can bite and harm your lizard.
I have a bearded dragon that’s 6 1/2, a leopard gecko that’s 8, and a water dragon that’s brand new I got on Mother’s Day.
Bearded dragons need greens daily. Google greens for bearded dragons. Not sure the age of yours but mine eats organic spring mix, I don’t have to chop it up anymore because she’s huge.
Have one side of the tank with a basking area and another that’s on the cooler side. Unsure how big your tank is, but they need space. Also letting them out if possible is always a nice thing to do.
I feed my Dubia roaches daily with greens so they have nutrients in them when the lizards eat them. I also feed them roach chow. I have 2 colonies… super easy to care for and they multiply slowly at first, but now it seems they multiply super fast!
Bearded dragons seem to be the easiest of all my lizards. Even though the water dragon is definitely quite cool.
