If someone told me a few years back that I would own a Tegu Lizard, I would have laughed and treated it like a joke!!

However, here I am! A proud owner of not one but two Tegu lizards and ready to take on more!

What changed? A lot of things did. Firstly, my friend got one, and I saw how happy it made him. Secondly, I had to look after his pet for a few days because he was going out of town. I was a bit apprehensive initially but soon realized how great these lizards are.

As soon as my friend was back, I asked him to get me one of my own. Now, there is no turning back! I have become a die-hard fan!!

The tegu Lizards are also well known as the Argentine Giant Tegu or the Black and White Tegu. It is a giant lizard and belongs to the Teiidae family of lizards. It is omnivorous and mostly lives in tropical rain forests and semi-arid areas of central and eastern South America. They are highly intelligent, and it is possible to train them. They hibernate for a part of the year and the rest of the time, are quite active. 

Tegu Lizard Size & Life Span 

As hatchlings, Tegus are quite small but soon start to grow large at a fast speed. The male adult Tegus can grow up to 4 or 5 feet while the female adults can grow to about 3 feet. A healthy Tegu can live up to 15 or more years in the wild and between 15 and 20 years in captivity. 

Appearance of the Tegu Lizard

As babies, they have an emerald green color on its head and back with some black markings. As they age, this color changes to black and white. As a young lizard, the tail has bands of yellow and black. The older they get, the lesser the bands. These bands can tell you about the age of your pet. The body has beaded skin.

When it feels any threat, it can drop a section of its tail as a distraction and escape. The tail is quite strong and can hurt an opponent in a fight. It has a big skull and has large facial muscles.

Tegu Lizard’s Living Conditions

  • These lizards like to well on grounds and are not very fond of heights. You will need a sizeable horizontal enclosure for your pet to live comfortably. It does not have to be too high. For an adult Tegu, a cabinet having dimensions 3 by 4 by 8 feet is ideal. For a smaller or younger Tegu, make sure that the tank is at least 2 by 2 by 4 feet. It is good to have a sliding glass or acrylic door and a lid that closes perfectly. If you have 3 smaller doors instead of 2 large ones, it can help while cleaning. 
  • You should clean and disinfect the habitat thoroughly at least once a week. Remove the lizard from the tank and scrub the tank well. Rinse and dry completely and then change the substrate before putting your pet back in. 
  • One end of the enclosure should be a hot spot, while the other purpose should be cold. It is a good idea to build a brick patio in the cabinet. Bricks retain heat, and the lizards can bask for a longer time. Above the blocks, you can hang a light fixture. This will provide warmth and light that your pet needs. 
  • The temperature should be between 90 and 110 degrees Fahrenheit. The cold end should have a temperature of about 70 to 85 degrees Fahrenheit. 
  • Wheat straw is a suitable substrate for the enclosure. It is cheap and readily available. You can place a 6-inch layer of straw. You can also use coconut fiber, cypress mulch, orchid bark, or any such substrate. These could be more difficult to find. 
  • They like to climb, so provide some sturdy branches and rocks in the enclosure. 
  • You should maintain humidity at about 75%. You may have to mist the tank often in the dry season. 
  • If you have more than one, then keep an eye on them. Do not put different species of reptiles together.
