By Tegus are large, fascinating lizards native to Central and South America, known for their striking appearance, intelligence, and docile nature, making them popular pets among reptile enthusiasts. Before adopting a tegu as a pet, it’s crucial to understand their dietary needs and preferences to ensure they live a healthy and fulfilling life. This comprehensive feeding guide will discuss everything you need to know about tegu nutrition, including their diet in the wild, suitable food options, feeding schedules, and potential risks associated with improper feeding.

Tegu Diet in the Wild
In their natural habitat, tegus are considered omnivorous scavengers, meaning they can eat a wide variety of food items, depending on what’s available. Their diet primarily consists of insects, eggs, fruits, and small animals such as rodents and other lizards. However, they also consume plant matter like leaves and opportunistically feed on invertebrates, carcasses, and animal tissues, including birds and other reptiles.
It’s important to note that the diet of tegus can vary depending on factors such as species, age, and geographical location. Argentine black and white tegus, red tegus, and Colombian tegus have different dietary preferences, with Colombian tegus being almost carnivorous, with only 10% of their diet consisting of fruits and vegetables.
Tegu’s Dietary Requirements by Age and Species Feeding Chart
Understanding your tegu’s species and age is essential to provide them with an appropriate diet. The table below outlines the general dietary requirements for different tegu species and age groups:
| Age/Species | Protein | Fruits | Vegetables |
|---|---|---|---|
| Hatchlings (0-6 months) | 90% | 5% | 5% |
| Juveniles (7-12 months) | 80% | 10% | 10% |
| Subadults (1-2 years) | 70% | 15% | 15% |
| Adults (Colombian Tegu) | 90% | 5% | 5% |
| Adults (Argentine/Red Tegu) | 60% | 10% | 30% |
As juveniles, all tegus require high amounts of protein to support their rapid growth. As they mature, their diet becomes more diversified, with Argentine and red tegus consuming more fruits and vegetables than Colombian tegus.
Tegu’s Feeding Schedule by Age
The frequency of feeding is another important aspect of tegu nutrition. Younger tegus require more frequent feeding than adults, as they need more energy and nutrients to support their growth.
| Age Group | Feeding Frequency |
|---|---|
| Hatchlings (0-6 months) | 5 times per week |
| Juveniles (7-12 months) | 4 times per week |
| Subadults (1-2 years) | 3 times per week |
| Adults (>2 years) | 2 times per week |
Keep in mind that these are general guidelines, and you should closely monitor your tegu’s appetite, growth, and overall health to make any necessary adjustments.
Tegu’s Portion Sizes and Precautions
When feeding your tegu, the portion size should be roughly the same size as its skull. This is particularly important when offering whole prey items, as tegus don’t chew their food and may choke on items that are too large. To ensure safety, always offer whole prey slightly smaller than your tegu’s skull.
It’s also crucial to prevent obesity in tegus, which can occur if they are fed too often or consume excessive amounts of rodents, fatty meats, fruit, or human food. Stick to a consistent feeding schedule and encourage exercise to maintain a healthy weight.
Suitable Tegu Food Options
Tegus can consume a wide variety of food items, but it’s essential to provide them with a balanced and varied diet that includes different types of insects, meat, fruits, and vegetables. Below is a list of suitable tegu food options, categorized by type:
Insects
Insects are an excellent protein source, especially for young and smaller tegus. Offer insects that are gut-loaded or dusted with calcium powder to ensure proper nutrient intake. Suitable insects for tegus include:

Tegu Feeding Techniques and Hunting Behavior
Tegus are cold-blooded reptiles that need to warm up their body temperature before foraging for food. Their digestive system won’t function properly without adequate internal body temperature. Tegus are not picky eaters and will consume anything they can catch or find in the wild.
These lizards use their forked tongues to detect prey, similar to snakes. They have a specialized organ called Jacobson’s organ, located on the roof of their mouth, which processes scent particles on their tongue. This organ helps them determine the direction of food sources by identifying the side of the tongue that picked up the scent.
Feeding Pet Tegus
When feeding a pet tegu, it’s essential to replicate their natural diet as closely as possible. Offer a healthy diet that includes a variety of prey, fruits, and vegetables, along with supplemented food items. Hatchlings and juveniles should be fed insects daily, while adults can be offered a mix of rodents, fish, and other protein sources.
Ensure that your tegu receives appropriate amounts of calcium and multivitamin supplements with their meals to maintain optimal health. Limit fruit consumption to prevent excessive weight gain.
Potential Dangers and Foods to Avoid for Tegu
Feeding your tegu an improper diet can lead to health complications such as obesity, nutrient deficiencies, and digestive issues. Avoid offering your tegu the following foods, as they can be harmful or even fatal:
- Avocado
- Azalea flowers and leaves
- Broccoli
- Buttercup flowers
- Eggplant
- Lettuce
- Marijuana or hemp leaves
- Onion
- Rosemary
- Sage
- Spinach
- Wild-caught insects (may contain pesticide residues)
In addition to avoiding these foods, it’s crucial to monitor your tegu’s health and growth to ensure they are receiving the proper nutrition and care.
Conclusion
Providing a balanced and varied diet is crucial for the health and well-being of your tegu pet. By understanding their dietary needs, preferences, and potential risks associated with improper feeding, you can ensure your tegu lives a healthy and fulfilling life. Always consult with a reptile veterinarian or specialist if you have concerns about your tegu’s diet or health.
