Bearded Dragon Habitat & Tank Setup

A bearded dragon's health starts with the tank, not the dragon. Get the setup wrong: low UVB, the wrong size enclosure, no real temperature gradient, and you'll spend months chasing health problems that were never about the dragon at all.

Size is where most setups go wrong first. A single adult bearded dragon needs at minimum a 120-gallon enclosure (4x2x2 feet), which gives it real room to move, bask, and thermoregulate properly. Babies can start smaller, but they outgrow a 20-gallon tank within months, so most keepers save money by building for adult size from day one.

Temperature and lighting do the heavy lifting after that. A bearded dragon needs a basking surface of 100 to 110 F, a cooler side of 78 to 82 F, and UVB lighting running 10 to 12 hours a day from a quality T5 fixture. Zoo Med's Reptisun and Arcadia's ProT5 are two of the most trusted names in reptile UVB, and either should be replaced every 6 to 12 months, since output fades before the bulb looks any different. Skip UVB or run an old bulb, and calcium from the diet stops absorbing properly, no matter how well you're feeding.

Substrate is the most argued-over piece of gear in the hobby, and for good reason. Loose sand and calcium sand carry real impaction risk for younger dragons especially, while tile, reptile carpet, or paper towel-lined setups cost less and carry zero risk. Most experienced keepers land on tile for exactly that reason.

Common questions

Bearded Dragon Habitat: Common Questions

How do you set up a bearded dragon tank?+
A bearded dragon tank setup needs a 120-gallon (4x2x2 foot) enclosure for an adult, a basking surface of 100 to 110 F on one side, UVB lighting running the full length of the tank, a solid substrate like tile or reptile carpet, and a cool side of 78 to 82 F so your dragon can move between temperatures.
What lighting does a bearded dragon need?+
A bearded dragon needs a basking bulb for heat and a separate UVB bulb for calcium absorption, both running 10 to 12 hours a day on a timer. Replace the UVB bulb every 6 to 12 months, since UVB output drops well before the bulb burns out or looks different.
What is the best substrate for a bearded dragon?+
Tile, reptile carpet, and paper towels are the safest substrate choices, especially for young bearded dragons, since they carry no impaction risk. Loose sand and calcium sand look natural but can cause impaction if ingested, so most experienced keepers avoid them, particularly under a year old.
What size tank does a bearded dragon need?+
An adult bearded dragon needs at least a 120-gallon (4x2x2 foot) enclosure to move and bask comfortably. A 40-gallon breeder tank suits a juvenile, and babies can start in a 20-gallon tank but outgrow it within months.
What temperature should a bearded dragon tank be?+
A bearded dragon tank needs a basking surface of 100 to 110 F, a cool side of 78 to 82 F, and a nighttime minimum of 65 to 70 F for most adult dragons. Use a digital thermometer at both ends to confirm the gradient, not just the thermostat setting.
