Argentine Black and White Tegu Care: Your Complete Guide

To care for an Argentine Black and White Tegu, you'll need to guarantee a proper habitat and temperature. Maintain a basking spot at 95-110°F, with cooler areas at 75-82°F. Keep humidity between 60-80%; misting helps. Tegus eat a variety of foods, from proteins like ground turkey to fruits such as bananas, and need fresh water daily. Enclosures should start spacious and grow with them, and monitor brumation without feeding. Be aware of legal requirements through the Lacey Act. There's more to master in their care, from nutrition specifics to creating the ideal environment.
Key Takeaways
- Maintain a basking area temperature between 95-110°F and a cooler side at 75-82°F for optimal health.
- Ensure humidity levels are kept between 60-80% through misting and the use of humid hides.
- Provide a balanced diet including proteins, fruits, vegetables, and supplements for proper nutrition.
- Adult tegus require a minimum enclosure size of six by three feet with deep substrate for digging.
- During brumation, avoid feeding and ensure legal compliance with regulations like the Lacey Act.
Essential Information
Argentine black and white tegus, often known for their striking appearance, require specific care to thrive. To guarantee your tegu's well-being, focus on maintaining proper basking temperatures and ambient temperature. The basking area should be kept between 95-110°F, while the cooler side should stay at 75-82°F. This temperature gradient is fundamental for their health, along with UVB lighting that helps in calcium absorption and general vitality.
Don't overlook the importance of humidity levels, which should range between 60-80%. This can be achieved by regular misting and providing a water dish to prevent dehydration and support proper shedding. The water dish also serves as an key source of hydration, so make sure it's always clean and full.
Your tegu's feeding schedule is another significant aspect. As omnivores, they require a balanced diet of proteins, fruits, and vegetables. Young tegus need daily meals, whereas adults should be fed every other day. This schedule helps in maintaining their energy levels and promoting growth.
Enclosure and Habitat
When setting up the enclosure for your black and white tegu, it's vital to provide ample space to accommodate their active and curious nature. An adult tegu requires a minimum enclosure size of six by three feet, ideally custom-built to allow for their natural behaviors. The enclosure should include a deep loose substrate like Zilla's Jungle Mix, which encourages digging and helps maintain the humidity levels between 60-80%. This is fundamental for their health and well-being.
Here are some key features to include:
- Temperature gradient: Guarantee a hot basking spot ranging from 95-110°F and a cooler side between 75-82°F.
- Hiding spots: Provide secure areas and a humid hide filled with wet moss or jungle mix for mental comfort.
- Fresh water: Always supply a bowl of fresh water for hydration and occasional soaking.
For hatchlings, a smaller 36 x 18 inch enclosure will suffice temporarily, but upgrading to a larger 90-gallon breeder cage as they grow is necessary. Creating a suitable environment with a temperature gradient and ample hiding spots will keep your tegu happy and healthy. Remember, a well-designed habitat is the foundation for thriving Argentine black and white tegus.
Lighting and Temperature

After setting up a spacious and well-equipped enclosure, it's time to focus on the lighting and temperature needs of your Argentine black and white tegu. Creating a proper temperature gradient is vital for their health. Make sure the basking area on the hot side reaches temperatures between 95-110°F and the cool side stays around 75-82°F. This allows your tegu to thermoregulate effectively. At night, let the temperatures drop to about 70°F to provide natural variation. Use reliable temperature gauges, like Zoo Med or Exo Terra, to monitor these conditions closely.
UVB light is imperative for your tegu's well-being, especially in their initial year, aiding in calcium absorption and vitamin D3 synthesis. A quality option is the Exo Terra Solar Glo mercury vapor bulb. Provide a light cycle with at least 8 hours of UVB exposure daily, ideally split into 4-hour sessions in the morning and before nighttime. Position your UVB light above the basking area, making sure your tegu can soak up the beneficial rays.
Incorporate a suitable heating element to maintain the desired temperatures, making certain your tegu thrives in a comfortable and healthy environment.
Humidity and Water
Maintaining proper humidity and water availability is vital for the health of your Argentine black and white tegu. Keep humidity levels in the enclosure between 60-80% to keep your tegu comfortable and thriving. A clean water dish is significant; change it daily to prevent bacteria buildup and guarantee your tegu stays well-hydrated. To create a microenvironment with higher humidity, consider adding a humid hide filled with wet moss or jungle mix.
Misting the enclosure a couple of times daily is a simple yet effective way to manage humidity levels, especially if the surrounding air is dry. Consistent misting keeps your tegu's skin healthy and prevents shedding issues. If manual misting becomes a chore, automatic misters, like the Exo Terra Monsoon, offer a dependable solution for maintaining steady humidity without constant attention.
Here are some tips to improve your tegu's environment:
- Humidity levels: Keep them between 60-80% for ideal health.
- Clean water dish: Replace daily to avoid bacteria buildup.
- Humid hide: Use wet moss or jungle mix to support hydration.
Feeding and Diet

A balanced diet is vital for the well-being of your Argentine black and white tegu. These omnivorous reptiles thrive on a varied diet, so when you're feeding them, include proteins like ground turkey, live insects, and whole prey items. Quail eggs are also a fantastic addition, providing fundamental nutrients. Young tegus should be fed every day, while adults require meals every other day. Always remember to adjust the size of prey to fit comfortably between the tegu's eyes to avoid any choking hazards.
Incorporating fruits and vegetables into their diet is necessary as they mature. Offer fruits like bananas, mangoes, and berries in moderation for a healthy dose of vitamins. Supplement their meals with calcium and multivitamins, such as those from Zoo Med, to support proper bone development and general health. Fresh water should always be available, and it's significant to replace the water dish daily to prevent bacteria buildup.
Brumation and Legal Considerations
Brumation is a natural, hibernation-like state that your Argentine black and white tegu might enter during the cooler months. This period can last from a few weeks to several months, and it's vital to provide deep substrate for burrowing and moisture retention. During brumation, avoid feeding your tegu, as undigested food can lead to toxicity. Instead, monitor your lizard periodically, but refrain from excessive handling.
Understanding the legal implications of owning a tegu is important. Some regions have specific local regulations that might restrict or ban tegu ownership due to their potential impact on local ecosystems. As a responsible owner, you should:
- Familiarize with legislation: Learn about the Lacey Act and other laws governing reptile transport and ownership.
- Engage with organizations: Groups like U.S. Ark offer resources to help guarantee compliance and promote responsible ownership.
- Monitor local changes: Stay updated on any shifts in regulations affecting tegu ownership.
