Best Bearded Dragon Tanks and Sizes

Bearded Dragons (Pogona vitticeps) are a popular and rapidly growing choice of reptile pets. Their unique behavior, great temperament, solitary life, and simple diets make these diurnal lizards one of the best reptile pets for starters.

In captivity, you need to home them in a vivarium, terrarium, tank, or cage with conditions that closely mimic those in their dry and warm natural environment being desert lizards.

Therefore, you need a vivarium itself (tank), and other supplies like lighting and heating sources, temperature and humidity monitoring and control devices, food, water, substrate, as well as some enrichments, among other supplies.

Vivarium, terrarium, or tank?

Since we may use some terms interchangeably, it is good to look at what vivarium, aquarium, and terrariums are briefly.

1. Vivarium (vivaria)

Refers to a semi-natural structure, container, or enclosure for keeping or raising animals or plants primarily for observation, research as pets, or decoration. It may be open to the atmosphere or not.

2. A terrarium (terrariums or terraria)

A terrarium is an open or sealable vivarium, enclosure or cage for keeping or raising reptile, amphibians, terrestrial invertebrates. It can also be for ornamental plants, and some terraria are open to the atmosphere.

3. Aquarium (aquariums or aquaria)

Aquariums are vivarium for keeping aquatic animals such as fish, African draw frogs, crayfish, shrimp,  Mystery snails, marine turtle, hermit crabs, or aquatic plants. It often has at least one transparent side. It may also be known as a tank, enclosure, etc., such as a fish tank.

Note that the terms reptile or amphibian tanks, cages, housing, vivarium, or enclosures will mean the same thing so long as they are for keeping terrestrial pets.

Bearded dragon tank or cage size

What size tank does a bearded dragon need? This common question, one of the most important when it comes to buying enclosures for these pets.

The answer is straightforward. The tank (vivarium, terrarium, or cage) size will depend on the age or size of your beardie and will influence its price. However, frequent upgrading may prove expensive in the long run if you have a young beardie.

1. Advice

Our best advice is you begin with a 40-gallon tank if you have baby bearded dragons and upgrade to at least a 75-gallon tank once they are above 15 months. It will cut on the total cost you spend on these cages since these reptiles grow very fast.

2. Why no to a small tank?

Going for a small tank will stress these pets, make them unhappy, depressed, stressed, or even affect their health as well as their healthy growth and development. They need enough room to move around freely, hunt, hide, explore, dig, climb, and play in. A small tank may make them feel trapped.

3. Vertical vs. horizontal space

Your beardie is not arboreal, therefore and ideal vivarium should have enough flat surface areas and a vertical one.

Therefore, when choosing a terrarium for these pets, measure their length from snout to tip of their tail tip to get their size and choose the right one.

The ideal tank (vivarium or terrarium) sizes (Width x Depth x Height) or (Length x Width x Height) is as follows.

4. Hatchlings and babies (0-2 months)

They measure below 4 inches after hatching, and their length will be about 5-9 inches by the time they are two months.

While hatchlings can stay in a 10-15 gallons tank and baby bearded dragons in an enclosure about 20 gallons, go for cages over 20 gallons.

Since they grow very fast, such tanks will only be a temporary place that will serve them for about 2-3 months. Instead, going for a 40-gallon tank as your pets can still use it until they are subadults).

While it is not bad, a large tank will make it hard for them to catch their food, especially feeder insects, and bugs but stimulate physical activity.

However, if you have good feeding bowls that will prevent these bugs from crawling out or feeders such as Exo Terra Reptile Cricket Feeders, feeding them should not be a big issue.

Buying a small one means you will have to upgrade after a short. In the long run, you may spend more and remain with small cages you don’t require.

4. Juveniles 10-16 inches long 2-7 months

Their typical size 5-9 inches at two months ad and 12-19 inches by the time they are seven months.

Juvenile beardies minimum of a 40-gallon tank with their depth is enough to allow them to turn around freely. Consider their length and width.

5. Subadults and adults (16-20 inches long)

Young subadults measure 12-19 inches, and the time they are 18 months, they will be 16-20 inches in size.

Subadults and adults whose size is 16-20 inches require a minimum tank size of 55 gallons tank with the 75 gallons being the ideal one. However, any medium size vivarium with capacity ranging from 50-75 gallons will still work well if its depth is not too small. This range includes a 60 gallon and 67-gallon tanks.

For instance, a 55-gallon tank, avoid those with a small depth such as the 48”x13”x 20” may not be the best choice. Instead go for the 50-gallon tank such as one with 36″ x 18″ x 18” or the 67-gallon vivarium measuring 36″ x 24″ x 18” or 48″ x 18″ x 18” or 36″ x 18″ x 18”.

6. Fully grown adults 20” + long

Adult bearded dragons can grow up to 24 inches. However, most are 18-22 inches long.

For a 20” + long, provide them with a minimum tank size of 75 gallons. However, the ideal size will be a 120 or 125-gallon tank.  An 80 gallon, 100 gallons, or other sizes will still work well.

Typical dimensions for the 75-gallon tank are 48”x18”x 20”, and the 120-gallon tank dimension are 48″ x 24″ x 24”. (4 feet by 2 feet by 2 feet).

There are even bigger terrariums such as the 60”x24”x24” or even larger available. While the bigger it is, the better, a massive one will require more resources such as to heat or light it properly.

7. How do I know its volume?

Since most dimensions are given in inches, to get its volume in gallons, multiply its size (WxDxH) in inches and divide by 231.

Enclosure buying tips

Different types of bearded dragon terrariums come in various designs. Besides size, which we have already covered in great details, other consideration great cages or enclosures include:

Consider tank dimensions not just volume

Since manufacturers of these tanks design them for fish, reptiles, and amphibians, check their sizes and not only their capacity. Its length should not be below of 32-36 inches.  recommends a minimum of 120 cm by 60 cm by 60 cm.

Some brands are tall (high in height) suitable for climbing, but if their depth or width is small, they will not be ideal for bearded dragons since they are only semi-arboreal. Such tanks don’t allow these pets to turn around freely.

Height is essential since these pets are semi-arboreal and will enjoy climbing but not as much as a frilled dragon would. However, this should not be a reason to compromise on a larger surface area.

1. Safety

It must be escape-proof and prevent the entry of predators like birds, snakes, feral cats, goannas, foxes, and dingoes.

Furthermore, their doors or lid (often made of wire mesh) should be secure (tightly fitting).

2. Types of cage

If you consider the material of construction, the typical reptile cage or terrarium types include glass, melamine, wood, PVC, plexiglass, vision cages (polyethylene). Avoid wire cages as they cannot retain heat and will cause nose abrasion to these pets.

3. How you will open it

While some designs feature a front sliding door, others have a top reptile screen. Those with a screen allow for better ventilation.

On the other hand, those with sliding ones will make your pets feel more secure since most predators attack them from the top side. Seeing their predators on top will scare them.

4. Durability and warranty

The average lifespan of a bearded dragon is 10-12 years. Some live longer than that. You need to get a durable tank that is going to last their entire lifespan.

To assure you that it will be durable, brands that come with some years of warranty will be better since you can always get replacement or repair while still in the warranty, especially to those sold as a complete kit with UV lighting, heat lamps, accessories as well as thermometers, hygrometers and so on.

5. Price or cost

Different cages come at different rates. You need to choose a functional one that is within your enclosure without compromising on its size. However, it should be within what you can afford.

6. Functionality

A good brand should be functional; this means it must do its intended purpose correctly. Anything less will not serve you well.

7. Visibility

Go for a brand will give you a chance to see your reptiles. At least, it should have a transparent front part. Some like glass allows you to see your pet from all angles.

8. Space economical – stackable vivarium

If you have limited space or you are a breeder, go for brands that are space-saving. For instance, a stackable bearded dragon tank or terrarium will save more space.

Usually, stackable ones should be light in weight and sturdy.

9. Personal liking – cool, fancy, and so on

Besides these attributes, it has to meet your personal preference. You may need an impressive or elegant looking cage, one that blends with your home décor, and so on. See pictures before you buy any.
