Ok, so, I have a Beardy, and he has a mealworm colony as well as a Dubio roach colony to feed him. Avocados are not good because of how much fat is in them. NEVER feed them. Veggies he eats are sweet potatoes, Cilantro, Arugula, Alfalfa Sprouts, Snap Peas, and Mustard Greens. Fruits he eats are Blueberries, Watermelon, Strawberries, and Apple. I have Sunny in a 65 gallon tank with a heat lamp and a heater. He has cinder blocks, a log, and a weird looking foam thing. I have an eyeballed 400-500 gallon diy sandbox converted into a chicken wire cage. It has spider wood, and more large wood. Plus some large rocks and etc.
I take him out every morning and bring him in every night. I can show u pics if u want. I do not recommend a beardy in a cage under 55 g because they can get up to 2+ feet. I suggest about 120 gallons for an adult Beardy, 48x24x24”. The reason I have him in a 65 is because he has time to go outside. Another important thing is that they like sand. Besides that, I think you have everything.
