3 Best 120 Gallon Bearded Dragon Tanks, Enclosures & Cages

A 120 gallon bearded dragon tank is the best size cage for bearded dragons. Because it can hold a specific range of temperature and provide ample space for your beardie to roam around and exercise.

In this post, we will discuss why a 120 gallon is the ideal tank size for bearded dragons. Also, we will be giving our reviews on some of the best 120 gallon terrariums on the market.

You will find mixed opinions online if you research the term “ideal cage size for bearded dragons“. Some experts recommend a 75-gallon enclosure for adult bearded dragons while others think this cage size is too small for them.

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 their tail).

So, rather than starting with a 20-gallon tank and buying larger tanks progressively as your 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.

Bigger enclosures also make it very easy to install heat and lighting equipment without compromising any space.

Is a 120 Gallon Tank Good For a Bearded Dragon?

Yes, a bearded dragon cage sized 4’ x 2’ x 2’ or 48 inches x 24 inches x 24 inches is the perfect size for a bearded dragon. It offers ample space for your bardie to run around and exercise. You can also install all the required heating and lighting equipment without compromising any space.

What is the Maximum Size Tank For a Bearded Dragon?

There are no maximum-sized tanks for beardies. The tank should not be smaller than 75 gallons and not bigger than 120 gallons for an adult bearded dragon. Your beardie might struggle to cache live food if the tank is bigger than 120 gallons.

Is a 50-Gallon Tank Big Enough For a Bearded Dragon?

A 50-gallon tank is OK for babies and juveniles but too small for adult-beared dragons. Fully grown dragons do best in a 120 gallon enclosure.

Conclusion

120 gallon is the perfect size enclosure for bearded dragons. Some people recommend 75 gallons for adult dragons but we think it’s too small for them. Instead of buying a smaller cage and then buying bigger cages progressively, we recommend getting a 120 gallon tank from the beginning. This way you will save a lot of money.
