What size tank for a 1 year old bearded dragon

What size tank for a 1 year old bearded dragon?

Here is a breakdown of the size of tank that you should get for each stage in your bearded dragon’s life:

  • Baby bearded dragon: 20-40 gallons
  • Juvenile bearded dragon: 55-75 gallons
  • Adult bearded dragon: 120 gallons

The size of the tank for a bearded dragon depends on its age and size. A juvenile bearded dragon should be housed in a 10-gallon glass aquarium tank, but the tank size will have to increase as the beardie grows. Adults require a 20-50 gallon long glass aquarium tank.

Factors to consider when choosing a tank size

Size and growth rate of a 1-year-old bearded dragon

Bearded dragons are relatively slow-growing reptiles, but their growth rate depends on factors such as diet, temperature, and genetics. At one year old, a bearded dragon can measure anywhere from 12 to 18 inches in length, excluding the tail.

Their weight can range from 300 to 600 grams. It is essential to remember that these measurements are just averages, and individual dragons may differ slightly in size.

Activity level, behavior, and accessories affecting tank size requirements

The activity level of your bearded dragon can influence its tank size requirements. A more active dragon will benefit from having a larger enclosure with plenty of room for exercise and exploration. Conversely, a less active or older beardie may prefer a smaller enclosure with more hiding spots.

The type and number of accessories you plan to add to the tank also impact its required size. For example, if you have lots of basking platforms or rock formations in your enclosure, this may limit the available space for your bearded dragon to move around.

Additionally, considering your beardie’s behavior is crucial when choosing an appropriate-sized tank. Do they tend to climb more than they walk?

Are they sociable or solitary? These behavioral factors will help you determine how much space they need in their habitat.

Special considerations for male vs. female dragonsMale bearded dragons tend to grow larger than females as adults due to their territorial nature during mating seasons.

While there isn’t necessarily an ideal tank size specifically for males versus females at one year old due to their similar sizes at this age range — it is still important to keep future growth in mind when selecting the right-sized habitat for them so that they do not feel cramped once they reach their full size.

When it comes to selecting an appropriate size tank for your 1-year-old bearded dragon, there are a few factors you need to consider. These include the size of your dragon, its activity level, and the accessories that will be placed in the enclosure.

The minimum recommended tank size for a 1-year-old bearded dragon is a 40-gallon tank with dimensions of at least 36 inches long, 18 inches wide and 18 inches tall.

This size can accommodate most bearded dragons up to around one and a half years old. The ideal size of the enclosure for a one year old bearded dragon should be between 75-120 gallons with dimensions of about four feet long by two feet wide by two feet tall.

A larger enclosure will allow more freedom of movement for your pet and provide ample space to bask, climb, and explore. The maximum recommended tank size depends on the space available in your home but should not exceed six feet long by three feet wide.

It’s important to note that these recommended sizes are just guidelines; every dragon is unique and may require more or less space depending on their individual needs. Factors such as activity level, gender, health status, and environment should also be taken into account when choosing an appropriate sized tank.

A 40-gallon tank has dimensions of approximately 36 x18 x18 inches (L x W x H) and can hold up to about about four pounds worth of substrate (e.g., Reptile Carpet or tile), which equals around two inches deep throughout the entire cage floor.

This allows enough room for hiding spots underneath basking areas or shelves while still providing enough space to move around comfortably.

An ideal 75-gallon tank has dimensions of about 48 x 18 x 24 inches (L x W x H) and can hold up to six pounds worth of substrate. This size is perfect for a one year old bearded dragon and will provide enough space for your pet to move around freely while still leaving enough room for accessories.

A larger tank, such as a 120-gallon, can accommodate more accessories and additional climbing structures that can help to encourage exercise. This size should have dimensions of approximately 48 x 24 x 24 inches (L x W x H) and can hold up to eight pounds worth of substrate.

Overall, selecting the appropriate size tank for your one year old bearded dragon is crucial to their health, growth, and overall well-being. By considering factors such as size, activity level, environment, and individual needs, you can ensure that your pet has plenty of space to thrive in its new home.

Tips for setting up a suitable habitat in the chosen tank size

Proper lighting

Bearded dragons require exposure to UVB light to properly absorb calcium and maintain healthy bones. A fluorescent tube-type bulb is recommended as it provides a wider coverage area than other types of bulbs. The bulb should be replaced every 6-12 months depending on usage and the manufacturer’s recommendations.


Bearded dragons also need a heat source to regulate their body temperature. A basking lamp with a spotlight bulb should be positioned on one end of the tank, creating a temperature gradient from around 75°F on the cool side to 100°F on the basking side. It is important to monitor and adjust temperatures regularly using a thermometer.


The substrate used in your bearded dragon’s tank should be safe and easy to clean. Avoid using loose substrates such as sand or gravel, as they can cause impaction if ingested. Reptile carpet, paper towels, or ceramic tiles are good options for substrate.


Adding decor such as rocks, branches, and hides can provide enrichment and stimulation for your bearded dragon. Make sure any materials used are safe for reptiles and do not have sharp edges or points that could injure your pet.

Food/water dishes

Use shallow dishes for both food and water that are easy for your dragon to access but too shallow to climb into or tip over. Ceramic bowls are recommended as they are sturdy and less likely to harbor bacteria than plastic dishes.

When selecting products or brands for use in your bearded dragon’s habitat, it is important to research their safety and effectiveness thoroughly.

Recommended brands for UVB bulbs include Zoo Med ReptiSun 10.0 Tube Bulbs and Exo Terra Repti Glo 10.0 Tube Bulbs. For basking lamps, Zoo Med’s Basking Spot Lamp and Fluker’s incandescent spotlight bulbs are popular choices.

When it comes to substrate, Zoo Med Eco Carpet and Reptile Prime Coconut Fiber Substrate are both safe options for your dragon’s tank. Use decor from natural sources such as branches or rocks found outdoors, but be sure to clean them thoroughly before introducing them into your pet’s environment.

Common mistakes to avoid when choosing or setting up a bearded dragon’s tank

As a new bearded dragon owner, it can be easy to make mistakes when selecting or setting up your pet’s enclosure. These mistakes can put your dragon’s health and wellbeing at risk and may even lead to serious health problems. To avoid these risks, here are some common mistakes that you should avoid:

Choosing the wrong size or type of tank

The size and type of tank that you choose for your bearded dragon can have a huge impact on their health and happiness.

Many new owners make the mistake of selecting a small or unsuitable tank, which can lead to stress, stunted growth, poor appetite, and other health problems. It is important to research the ideal tank size for your dragon based on their age, size, behavior patterns and provide them with adequate space.

Neglecting UVB lighting

One of the most common mistakes made by new bearded dragon owners is neglecting UVB lighting in their pet’s enclosure. Bearded dragons need exposure to UVB light for proper vitamin D synthesis, which is essential for strong bone growth and overall health. Without this essential light source, they may suffer from metabolic bone disease resulting in deformities.

Providing an inappropriate diet

Diet plays a critical role in keeping your bearded dragon healthy and happy. It is vital that they get balanced meals containing protein as well as plant matter such as leafy greens; failure to do so could result in malnutrition leading to illnesses such as Metabolic Bone Disease.

Inadequate temperature gradients

Bearded dragons require specific temperature ranges throughout their habitat so they can thermoregulate effectively – basking spots at around 40C and cooler areas at around 30-32C. Failure to provide adequate temperature ranges can lead to lethargy, poor appetite, and other health problems.

Using hazardous substrates

Many popular substrate materials such as sand or crushed walnut shells can be hazardous to your beardie’s health. When ingested, these materials cannot be digested by your pet leading to impaction which is fatal if not caught in time.


After learning about the factors to consider when choosing the right tank size for your 1-year-old bearded dragon, recommended sizes, and tips for setting up a suitable habitat, you should now feel confident in creating an ideal living space for your pet.

Remember that providing a safe and comfortable environment is essential to maintaining your bearded dragon’s health and happiness.

By following the guidelines discussed in this article, you can ensure that your pet has room to grow, exercise, and explore while receiving proper lighting, heating and nutrition. A well-crafted habitat will also contribute to a positive quality of life for both you and your beloved pet.
