Tegu Lizard Pet: The Ultimate Guide to Tegu Lizards as Pets

Tegu lizards have become increasingly popular as exotic pets, known for their intelligence, calm temperament, and impressive size. These fascinating reptiles are native to South America and belong to the Tupinambis genus. If you’re considering a tegu lizard pet, this guide will provide you with essential information on their care, behavior, habitat needs, and why they make excellent pets for experienced reptile keepers.

What is a Tegu Lizard?

Tegu lizards are large, ground-dwelling reptiles native to Central and South America, particularly in countries like Argentina, Brazil, and Paraguay. There are several species of tegu lizards, with the Argentine tegu (Salvator merianae) and Colombian tegu (Tupinambis teguixin) being the most commonly kept as pets. Tegus are known for their distinctive appearance, with robust bodies, long tails, and striking patterns on their scales, which can include a mix of black, white, and red colors.

They are highly intelligent reptiles, often compared to dogs in terms of their ability to recognize their owners and even learn simple commands.

Size and Lifespan of Tegu Lizards

Size:
Tegu lizards are among the largest pet lizards, with adult Argentine tegus typically reaching 3-4 feet (90-120 cm) in length, and weighing 10-15 pounds (4.5-6.8 kg). They have muscular bodies and powerful jaws.

Lifespan:
Tegu lizards have a long lifespan, often living up to 15-20 years in captivity if properly cared for. This makes them a long-term commitment, and potential owners should be prepared for the responsibility of caring for them over many years.

Temperament of Tegu Lizards

Tegu lizards are known for their calm and social nature. Unlike some other reptiles, tegus are often described as being dog-like in their ability to form bonds with their owners. They are curious creatures that enjoy interacting with humans and can be very affectionate, especially if they are raised in a household from a young age.

Adult tegus may be more reserved but can still be handled with care. Young tegus tend to be more energetic and curious, but they generally become more docile as they mature. Regular interaction and proper handling are key to ensuring a well-behaved and friendly pet.

Handling Tips:

  • Start handling your tegu when it’s young to build trust.
  • Avoid sudden movements or loud noises that could startle your pet.
  • Ensure that your tegu feels secure during handling by supporting its body.

Diet and Feeding

Tegu lizards are omnivores, which means they eat a wide variety of foods, including both animal and plant matter. Their diet should consist of:

  1. Protein: Insects (such as crickets, locusts, and roaches), small mammals (like mice), and eggs are great protein sources.
  2. Fruits and Vegetables: A variety of leafy greens, fruits (such as berries, melons, and bananas), and vegetables (like squash and bell peppers) should be included in their diet.
  3. Supplements: Tegu lizards benefit from calcium and vitamin D3 supplements, especially if they are kept indoors. These supplements help prevent metabolic bone disease.

Feeding Frequency:

  • Young tegus need to eat daily, with their diet consisting mostly of insects and some plant matter.
  • Adults should be fed every other day or 3-4 times a week, with a more varied diet of fruits, vegetables, and proteins.

Tegu Lizard Habitat Requirements

Providing the right habitat is crucial for keeping a tegu lizard healthy and happy. Since they are terrestrial reptiles, their enclosure needs to be large enough to allow them to roam comfortably.

Enclosure Size:

  • Young tegus: A 40-55 gallon tank or enclosure is suitable for young lizards.
  • Adult tegus: As they grow, they will need a larger space, ideally a 75-100 gallon enclosure or even a custom-built enclosure. An outdoor enclosure is ideal if you live in a warm climate.

Temperature and Humidity:

  • Basking spot: Tegu lizards require a basking area with temperatures between 95-100°F (35-38°C). This will allow them to regulate their body temperature.
  • Cooler side: The cooler side of their enclosure should be around 75-80°F (24-27°C).
  • Humidity: Tegus prefer moderate humidity levels between 50-60%. Regular misting and a water dish will help maintain the proper humidity.

Lighting:
Tegu lizards require UVB lighting to help them metabolize calcium and maintain healthy bones. Provide a 10-12 hour day/night cycle for your tegu, with appropriate UVB light for at least 10-12 hours a day.

Tegu Lizard Care and Health

Tegu lizards are relatively low-maintenance compared to other exotic pets, but they still require attention to detail when it comes to their care.

Health Checks:
Regular health checks are important to ensure your pet tegu is thriving. Look out for signs of illness such as loss of appetite, lethargy, skin shedding problems, or respiratory issues. A vet that specializes in reptiles should be consulted for regular check-ups.

Common Health Concerns:

  • Metabolic Bone Disease: This can occur if a tegu is not provided with adequate UVB light or calcium supplementation.
  • Parasites: Tegus, like other reptiles, are prone to internal parasites, especially if fed wild-caught prey. Regular fecal exams can help prevent issues.
  • Skin Issues: Tegu lizards molt regularly, and improper humidity can cause difficulty shedding. Be sure the humidity levels are within the recommended range.

Tegu Lizard as a Pet: Pros and Cons

Pros:

  • Intelligent and Interactive: Tegus are known for their ability to recognize their owners, respond to training, and form bonds.
  • Docile Nature: While they can be territorial as juveniles, most adult tegus are calm and easy to handle.
  • Long Lifespan: With proper care, tegu lizards can live for up to 20 years or more, making them long-term companions.

Cons:

  • Size: Adult tegus can be quite large and require a spacious enclosure. This might not be ideal for small living spaces.
  • Dietary Requirements: Tegus need a varied and balanced diet, which can be more demanding than other pet reptiles.
  • Commitment: Due to their long lifespan, tegus require a long-term commitment from their owners.

Conclusion

A tegu lizard pet can be a fantastic companion for reptile enthusiasts, especially those with some experience in reptile care. Their intelligence, docile nature, and impressive size make them a captivating species to keep, but they do require attention to detail, a proper diet, and an appropriate habitat to thrive. If you're ready for the challenge, a tegu can be a rewarding and fascinating addition to your home for many years.
