Well for a bearded dragon you need to have a 100watt heat bulb kept on for 12 hours a day and a uvb light 10.0 kept on 12 hours a day. Then at night get a ceramic heat emitter 60-70watt. Those lights alone can cost $100. Also you cant use any lose substrate so you have to use reptile carpet, tile, ect. I suggest you also get a thermometer to know what the degrees are in the tank. You need a high basking spot perfferablly a black rock because it attracts heat better than brown rocks. You need a water and salad dish. Change the water everyday and give them fresh salad everyday the salad can have kale, collard greens, mustard greens, turnip greens, any squash, carrots not alot though and apple. Aslo alot of other things as a treat like blueberries. You need to feed it crickets everyday or a different feeder of your choice but crickets are good. As for treats you can feed mealworns, waxworms and more. You need calcium too. D3 calcium is needed it helps there bones. The tank has to be atleast a 40gallon breeder for a beardie to be comfy. Thats about all. Good luck(:
