Is a 20-Gallon Tank OK for a Bearded Dragon?

Bearded dragons are a popular choice for pet reptiles, with their docile nature and unique demeanor charming reptile enthusiasts all over the world. As a responsible pet owner, it's critical to provide the best care for your bearded dragon throughout its life. One of the most important considerations is the size of their enclosure. A 20-gallon tank is a popular choice for many new bearded dragon owners, but the question arises – is a 20-gallon tank ok for a bearded dragon?

In this article, we'll explore the suitability of a 20-gallon tank for bearded dragons, taking into account their size, behavior, and specific needs.

Bearded Dragon Size and Habitat Requirements

Bearded dragons are known for their hearty appetite and love of basking in the sun. They are relatively large lizards that require ample space to move around, explore, and regulate their body temperature. Adult bearded dragons can grow up to 22 inches in length, with the tail accounting for almost two-thirds of their total length. Furthermore, they require 10-12 hours of UVB lighting per day, which helps them absorb calcium and maintain their overall health.

When it comes to their enclosure, bearded dragons require a habitat that replicates their natural environment, which includes both basking areas and cooler regions. They also need appropriate substrate depth for burrowing, hiding spots, and climbing structures. A bearded dragon's enclosure should provide more than just a place for them to exist – it should be a vibrant and enriching environment that supports their mental and physical well-being.

20-Gallon Tank Dimensions and Available Space

A 20-gallon tank is a popular choice for many new bearded dragon owners due to its affordability and convenience. However, it's crucial to evaluate the available space within the tank to ensure it meets your bearded dragon's size requirements and stimulates their natural behaviors. A standard 20-gallon tank measures 30 inches long, 12 inches wide, and 12 inches high, providing a total volume of 2400 cubic inches.

While a 20-gallon tank may suffice for a juvenile bearded dragon, as they grow to adulthood, it quickly becomes too small to accommodate their size and specific needs. In terms of available space, a 20-gallon tank can provide up to 200-250 square inches of floor space, which is insufficient for a fully grown bearded dragon to thrive. Furthermore, the height of the tank may limit the ability to add adequate basking spots and prevent natural climbing behaviors.

Suitability of a 20-Gallon Tank for Juvenile Bearded Dragons

While a 20-gallon tank is inadequate for adult bearded dragons, it may suffice for juvenile beardies if appropriately set up and maintained. Young bearded dragons require a smaller enclosure that is easy to access and maintain. In some cases, this may mean starting off with a 20-gallon tank. However, it's crucial to monitor your bearded dragon's growth and behavior and plan for a larger enclosure as they mature.

A 20-gallon tank for a juvenile bearded dragon should include appropriate substrate depth, basking lights, and a UVB light source. The temperature gradient within the enclosure should range from 100-110°F on the basking side and 80-90°F on the cool side. The ambient temperature inside the tank should remain between 75-85°F.

As a responsible pet owner, it's essential to provide your bearded dragon with regular exercise and mental stimulation. Combat boredom by adding climbing structures, hiding spots, and a variety of decorations to the tank. Additionally, take your bearded dragon outside for supervised exercise and exposure to natural sunlight when weather permits.

When to Upgrade from a 20-Gallon Tank

Bearded dragons grow exceptionally quickly, with some reaching 16 inches within their first year of life. As a result, a 20-gallon tank will soon become too small to accommodate their size and specific needs. It's essential to plan for larger enclosures as your bearded dragon matures to ensure their ongoing health and happiness.

The most suitable enclosure size for a bearded dragon is a minimum of 75-gallons. However, this size should only be considered the starting point for larger species, with some bearded dragons eventually requiring enclosures exceeding 120-gallons. The enclosure width and length should be no smaller than 4 feet, and the height should be at least 18 inches. The enclosure should accommodate appropriate substrate depth, multiple basking spots, and UVB lighting sources.

In addition to providing a larger enclosure, you may also need to consider additional heat and lighting sources as your bearded dragon grows. Larger enclosures can create more significant temperature and lighting gradients, requiring multiple light sources to provide adequate heating and basking areas.

Conclusion

While a 20-gallon tank may be a suitable starting point for juvenile bearded dragons, it quickly becomes inadequate as the bearded dragon grows to adulthood. Providing a larger enclosure that stimulates their natural behavior and accommodates their size is crucial for their health and happiness. A 20-gallon tank may suffice for a short amount of time, but eventually, you will need to plan for an enclosure that meets their specific needs, including appropriate substrate depth, basking spots, and UVB lighting sources. Providing a vibrant and enriching environment for your bearded dragon, regardless of size, is essential for their overall well-being and longevity.
