What basking temperature does a bearded dragon need?

The basking spot should reach 38–42°C, measured with a digital thermometer at the basking surface — not the tank wall. The cool end should be around 22–26°C so your dragon can thermoregulate.

How often should I replace UVB bulbs?

Replace UVB tubes every 6–12 months depending on manufacturer guidance — output declines before the tube stops glowing. Position within the recommended distance with no mesh blocking UV if possible.

What humidity is correct for bearded dragons?

Adults thrive at roughly 30–40% ambient humidity. Too damp causes respiratory and skin problems; too dry affects shedding. A shallow water dish and occasional misting help hydration without soaking the vivarium.
