Best 120 Gallon Bearded Dragon Tank

Bearded dragons are semi-arboreal species, and therefore need more horizontal space than vertical. They spend most of their time on branches, in bushes, and near human habitation. They bask on rocks and exposed branches in the mornings and afternoons.

You will find mixed opinions online if you research the “ideal cage size” for bearded dragons. For example, some experts recommend a 75-gallon enclosure for adult bearded dragons while others think this size is too small for them. In this article, we are going to explain why a bigger tank is better for bearded dragons.

The minimum recommended enclosure size for a baby bearded dragon is 20-gallon. But keep in mind that bearded dragons can grow very quickly and they will soon outgrow the 20-gallon tank. You will need to buy a bigger tank ideally 120-gallon in a matter of few months.

Note: Healthy bearded dragons can grow up to 2 ft. long (inclusive of its tail).

So, rather than starting with a 20-gallon tank and buy larger tanks progressively as your bearded dragon grows, it’s better to go for the 120-gallon tank and have your beardie grow into it. Regardless, you don’t necessarily have to stick with the minimum tank size requirements.

We recommend getting the biggest cage possible. Doing so ensures your beardie has enough room to roam around and exercise. Bigger enclosures also make it very easy to install heat and lighting equipment without compromising any space.
