Gold Tegus are harder to domesticate than other types of Tegus. Due to this, it is recommended that only advanced herpetologists keep this type of lizard.


Gold Tegus are large lizards, measuring from 34 to 43 inches long. They will weigh between 7 and 8 pounds. This Tegu has a glossy body with golden and black bands alternating on it. Their legs and tail are thick and strong.

How to Take Care of the Gold Tegu

Habitat, Tank Conditions & Setup

The minimum size of your Gold Tegu tank should be 4 feet wide by 2 feet long. If you have a bioactive substrate, you will only need to do spot cleaning of the tank from the defecation of the Tegu. If you have a regular substrate, it will need to be cleared out fully every 3–4 months. You should have a very shallow tub of water for your Tegu to bask in and drink from. This should be cleaned out daily or every other day.


In order to help your Tegu get the appropriate amount of vitamin D, you should use a UV-B bulb to light their enclosure.

Heating (Temperature & Humidity)

The ambient temperature of the tank should be around 80°F, while their basking area should be around 120°F–130°F. The humidity should be kept around 80%. This can be achieved with a humidifier. You may need to enclose parts of the top of the tank with plastic wrap to keep the humidity this high. Never put plastic wrap near heat lamps, though.

Tegus like to bury and dig in their substrate, so you should have a nice deep layer of substrate in their setup. A good substrate mix can be made with the following ingredients, which you can buy at a pet store or local hardware store: peat moss, topsoil, and coco bark. Mix in equal parts to provide the perfect substrate for your Tegu that has the added benefit of holding moisture well.

Tank Recommendations
Tank Type 4’ W x 2’ L
Lighting UV-B lamp
Heating Ambient 80°F, sunning spot 120°F–130°F
Best Substrate Mixture of peat moss, topsoil, and coco bark

Keeping Your Gold Tegu Healthy

These unique lizards are not commonly kept as pets, so many health issues are not known about them. That said, here are common health issues that Tegus may suffer from:

  • Metabolic bone disease. This is caused by an imbalance of phosphorus and calcium. Signs include limping and bowed legs. Dietary improvements are the main treatment of this disease.
  • Reptile fungus. This is caused by too high humidity and too low temperature in an enclosure. Signs include weight loss and appetite loss. Antifungal medications can be used to treat this fungus.


These large lizards will live anywhere from 12 to 20 years in captivity.


Gold Tegus are almost never bred in captivity due to the difficulty of getting two Tegus to mate. In the wild, Gold Tegus will mate after they emerge from brumation. Once a female Tegu’s eggs have been fertilized, she will lay them in a nesting burrow. The babies will then hatch after 154–170 days.

Are Gold Tegus Friendly? Our Handling Advice

Golden Tegus are difficult to domesticate, so it is best to handle them with gloves. This will help shield you from any bites that the lizard may try to give you.

Shedding & Brumation: What to Expect

This lizard goes through brumation, which is a dormant period for lizards. During this time, the Tegu will not eat, defecate, drink, or move for several weeks. Tegus also do not shed in one piece like a snake; they will shed one part of their body at a time.
