If you’re an experienced reptile keeper and ready for a large lizard pet, there are many species that offer exciting challenges, fascinating behaviors, and unique appearances. These lizards require more space, specialized care, and a deeper commitment than smaller species, but they can make incredible companions for those willing to put in the effort. In this article, we’ll explore some of the best large lizard pets you can keep, along with essential care tips to help them thrive.

1. Bearded Dragon (Pogona vitticeps)

Size: 12-24 inches

Lifespan: 10-15 years
Care Level: Beginner to Intermediate

While not the largest of lizards, bearded dragons are one of the most popular and commonly kept species in the pet trade. They can grow up to 24 inches long, including their tail, making them a medium-sized species. Bearded dragons are known for their friendly, social nature and can interact with their owners. Their care is relatively straightforward compared to other large lizards, which makes them ideal for those transitioning to larger reptiles.

Habitat Requirements:

• A minimum of 40-75 gallon enclosure for an adult.
• UVB lighting for calcium absorption and proper bone health.
• Temperature gradient with a basking area around 95-105°F (35-40°C) and cooler areas of 75-85°F (24-29°C).

2. Green Iguana (Iguana iguana)

Size: 4-6 feet
Temperament: Territorial, but can be tame with handling
Lifespan: 20-30 years
Care Level: Advanced

Green iguanas are one of the largest lizards you can keep as a pet. These majestic reptiles can grow up to 6 feet long, including their tail, and require ample space to roam. Green iguanas are often admired for their beauty, but they come with high maintenance and space demands. They are best suited for experienced reptile keepers who can meet their needs for heat, humidity, and space.

Habitat Requirements:

• A huge enclosure (at least 75-100 gallons for adults).
• UVB lighting is critical for bone health and metabolic processes.
• The enclosure should provide a basking area of 95-100°F (35-38°C), and the cooler areas should be 75-80°F (24-27°C).
• High humidity (65-80%) is essential for their skin and overall health.

Diet: Green iguanas are herbivores, eating a variety of leafy greens, fruits, and vegetables. They require a high-fiber diet and should avoid protein-heavy foods.

3. Savannah Monitor (Varanus exanthematicus)

Size: 3-4 feet

The savannah monitor is a large species of monitor lizard that can reach up to 4 feet in length. These lizards are relatively docile but can be shy, especially in the beginning. With consistent, patient handling, they can become comfortable with their owners. Savannah monitors require a spacious, secure habitat with both basking areas and places to hide.

Habitat Requirements:

• A minimum of 75-100 gallon enclosure for an adult.

• High humidity of around 40-60% is ideal.

Diet: As carnivores, savannah monitors require a diet of insects, small rodents, and eggs. They are opportunistic hunters and benefit from a varied diet.

4. Argentine Tegu (Salvator merianae)

Size: 3-4 feet

They are active and curious and require a large, secure enclosure with plenty of enrichment.

Habitat Requirements:

• 80-100 gallon tank for an adult tegu.
• UVB lighting is required for vitamin D synthesis and calcium absorption.
• Basking temperature should be around 95-110°F (35-43°C), with cooler areas around 75-85°F (24-29°C).
• High humidity (60-80%) is ideal, and they should have access to a water dish large enough to soak in.
