Tegu lizards are becoming increasingly popular as exotic pets. Known for their intelligence, impressive size, and unique appearance, tegu lizards can make excellent pets for the right owner. This guide will provide you with all the details you need to care for a tegu lizard, including their habitat, diet, behavior, and handling.
What is a Tegu Lizard?
Tegu lizards are large, powerful reptiles native to South America. They belong to the genus Salvator and are part of the family Teiidae. There are several species of tegu lizards, but the most common pet species is the Argentine tegu (Salvator merianae), followed by the Colombian tegu (Salvator rufescens).
Tegus are known for their size. Some can grow up to 4 feet in length, making them one of the largest pet lizards. They are omnivores, meaning they eat both plant and animal matter. Tegus are also highly intelligent, capable of recognizing their owners and being trained to some extent.
Tegu Lizard Appearance
Tegu lizards have a distinct look. They have robust bodies, large heads, and strong legs. Their coloration can vary depending on the species and age, but they are often seen with a mix of black and white patterns. Baby tegus are usually darker with a more vibrant appearance, while adults tend to become more muted in color.
They also have a long tail, which they use for balance and defense. Their scales are tough, and they have sharp claws, which help them dig and climb. Tegus have keen eyesight, which aids in both hunting and navigating their environment.
Setting Up a Tegu Lizard Habitat
Creating the right habitat for your tegu is essential for its health and well-being. Since tegus are native to warm, humid environments, replicating these conditions is key to keeping your pet comfortable.
Enclosure Size
Tegu lizards need large enclosures. A minimum of a 6-foot long tank is recommended for an adult tegu, but larger enclosures are always better. These lizards are active and need plenty of space to roam. A larger enclosure also allows you to set up areas for basking, climbing, and digging.
You can use a large glass tank, a custom-built wooden enclosure, or even an outdoor enclosure, provided the temperature and humidity levels are controlled. The enclosure should have a secure lid because tegus are excellent escape artists.
Temperature and Lighting
Tegus are cold-blooded, meaning they rely on external sources of heat to regulate their body temperature. The temperature in the enclosure should range from 75°F (24°C) at the cooler end to 95°F (35°C) at the warmer end. A basking spot should be provided at the high end, where temperatures can reach 110°F (43°C) to simulate the hot South American environment they are accustomed to.
A UVB light is essential for your tegu’s health. UVB helps them synthesize vitamin D3, which is crucial for calcium absorption. Ensure the UVB light is on for 10-12 hours a day. If your tegu is kept outdoors, ensure they can access both shaded and sunny areas for optimal health.
Humidity
Tegus thrive in humid environments. The humidity level in their enclosure should be kept around 60-80%. A humidity gauge will help you monitor this. To maintain the proper humidity, you can mist the enclosure daily and provide a water dish large enough for your tegu to soak in. Adding moist substrate like coconut fiber or soil will also help retain moisture.
Substrate
The substrate in the enclosure should be safe and comfortable for the tegu. Avoid using sand or loose gravel, as these can be ingested and cause impaction. Instead, use reptile carpet, coconut coir, or a mix of organic soil. These substrates help maintain humidity and provide a surface for digging and burrowing, which tegu lizards love to do.
Hiding Spots and Decorations
Tegu lizards need places to hide, especially when they are shedding or stressed. You can add hide boxes or caves in the cooler parts of the enclosure. Branches, logs, and other decorations also give your tegu a chance to climb, which is an important form of enrichment for them.
Feeding Your Tegu Lizard
Tegu lizards are omnivores and will eat a variety of foods. A balanced diet is crucial to keep them healthy and active. The key to feeding a tegu is to provide both plant-based and animal-based foods.
Animal Protein
Tegus are opportunistic feeders, and they will hunt small animals in the wild. In captivity, you can feed them a variety of proteins, including:
Insects: Crickets, roaches, and worms are great options.
Meat: Lean meats like chicken, turkey, or beef are beneficial.
Eggs: Raw or scrambled eggs are a great source of protein and fat.
Fruits and Vegetables
Tegus also enjoy a variety of fruits and vegetables. Some good options include:
Fruits: Berries, bananas, apples, and melons.
Vegetables: Dark leafy greens like collard greens, dandelion greens, and kale. You can also feed them squash, carrots, and bell peppers.
Supplements
To ensure your tegu is getting all the nutrients it needs, you should dust their food with calcium and vitamin D3 supplements. These are especially important for growing tegus and those kept indoors without natural sunlight. Be sure to follow the recommended dosages on the supplement packaging.
Feeding Schedule
Adult tegus should be fed 2-3 times a week, while younger tegus should be fed daily. It’s important not to overfeed your tegu, as they can become obese if given too much food. Always remove any uneaten food from the enclosure to avoid it rotting.
Tegu Lizard Behavior
Tegu lizards are known for their intelligence and curious nature. Unlike some reptiles that are more solitary, tegus tend to be social creatures. They can bond with their owners and may recognize them over time. Some tegu owners report that their lizards enjoy being petted and even enjoy social interaction.
Handling Your Tegu
Tegu lizards can be handled, but it’s important to do so properly. They are strong and can be a bit intimidating due to their size. When handling a tegu, always support its body, especially its tail and legs. If you are unsure, start by allowing your tegu to become accustomed to your presence by sitting near its enclosure and offering food.
It’s important to handle your tegu regularly to keep it tame, but avoid excessive handling, as this can stress the animal. If a tegu feels threatened, it may hiss, puff up, or even bite. Always handle your tegu gently and calmly.
Aggression
Tegus can sometimes display aggression, especially during breeding seasons or if they feel threatened. However, with proper care and socialization, most tegus become docile pets. If aggression becomes a problem, consult with a reptile behavior expert to help manage it.
Shedding
Tegu lizards shed their skin periodically. During this time, they may become more irritable or less active. Provide a humid hide for your tegu during shedding to help the process. It’s important not to pull off any loose skin as this can cause injury. If shedding becomes problematic, you can bathe your tegu in warm water to help loosen the skin.
Health and Care Tips
Tegu lizards, like all reptiles, require regular health check-ups to ensure they are healthy. Here are some tips for keeping your tegu in top shape:
Vet Visits
Tegu lizards should be taken to a reptile vet for an annual check-up. A vet can check for common health issues, such as respiratory infections, parasites, or metabolic bone disease. Regular vet visits can catch potential problems early and ensure your tegu lives a long, healthy life.
Cleanliness
Maintaining a clean enclosure is essential for preventing diseases and keeping your tegu healthy. Clean the water dish daily, remove waste and uneaten food, and spot clean the substrate as needed. Perform a deep clean of the entire enclosure once a month, replacing the substrate and disinfecting all surfaces.
Monitor Behavior
Keep an eye on your tegu’s behavior. If you notice any signs of illness, such as lethargy, loss of appetite, or unusual shedding, consult a veterinarian immediately. Early detection is key to effective treatment.
Tegu Lizard Lifespan and Longevity
Tegu lizards are long-lived pets. With proper care, they can live for 15-20 years or more in captivity. Their long lifespan makes them a significant commitment, so it’s important to ensure you are ready for the responsibility before getting one.
Conclusion
Tegu lizards can make fantastic pets for experienced reptile keepers. Their large size, intelligence, and engaging personalities make them a rewarding species to care for. However, they do require a significant commitment in terms of space, diet, and attention. By providing the proper environment, feeding them a balanced diet, and giving them plenty of social interaction, you can enjoy the companionship of a healthy and happy tegu for many years to come.
