Monitor lizards are fascinating reptiles that make great pets for the right owners. Known for their intelligence, unique appearance, and active behavior, they offer a lot of excitement in a terrarium. However, not all monitor lizards are suited for beginners, and it’s essential to choose the right species that fits your experience level and lifestyle. In this article, we will explore the best pet monitor lizards, their care requirements, temperament, and other key factors to consider.
Understanding Monitor Lizards
Monitor lizards belong to the family Varanidae and are found in Africa, Asia, and Australia. They are known for their long, muscular bodies, sharp claws, and keen senses, making them excellent hunters in the wild. These lizards are also known for their intelligence and curiosity, which makes them interesting pets.
Some monitor lizards can grow to large sizes, while others remain relatively small. Because of their varied sizes, behaviors, and needs, it’s important to choose the right species if you’re thinking about adding one to your home.
Characteristics of Monitor Lizards
Monitor lizards have several key traits that distinguish them from other reptiles:
Size: Some species, like the Komodo dragon, can grow to be over 10 feet long. However, there are smaller species that are better suited for a home environment.
Diet: Most monitors are carnivores and enjoy a diet of insects, small mammals, and sometimes fruits or vegetables.
Intelligence: Monitor lizards are among the most intelligent reptiles. They can learn to recognize their owners, solve problems, and even interact with toys or objects.
Socialization: They tend to be solitary creatures, but some species can become more docile with regular interaction.
Best Pet Monitor Lizards
Not all monitor lizards are suitable for keeping as pets, especially for beginners. Some species are too aggressive or require a large space that is difficult to provide in a typical home. Below are some of the best pet monitor lizards that are manageable for pet owners.
1. Ackie Monitor (Varanus acanthurus)
Overview: The Ackie monitor is one of the smallest and most popular monitor lizards kept as a pet. It is native to Australia and can grow up to 3 feet in length. Its manageable size, relatively docile temperament, and interesting behaviors make it an ideal choice for reptile enthusiasts.
Care Requirements:
- Enclosure: A 40- to 75-gallon tank is recommended for an adult Ackie monitor. They are active lizards, so the enclosure should be long and spacious, with plenty of climbing structures.
- Temperature and Lighting: Ackie monitors require a basking spot around 110°F and a cooler side of the enclosure at 80°F. UVB lighting is essential for their health.
- Diet: They are omnivores, so their diet should consist of insects, small vertebrates, and some fruits and vegetables.
Temperament: Ackie monitors are known for their curiosity and can become accustomed to handling with patience. While they are not as aggressive as larger monitor species, they still need careful attention and socialization to avoid skittish behavior.
2. Savannah Monitor (Varanus exanthematicus)
Overview: The Savannah monitor is a larger species, reaching lengths of 4 to 5 feet. Native to Africa, it is one of the most commonly kept monitor lizards in captivity. While they are relatively easy to care for, they require more space and attention than smaller species.
Care Requirements:
- Enclosure: A large enclosure (at least 75-100 gallons) is necessary for a Savannah monitor, especially as it matures. The enclosure should have plenty of hides, basking spots, and substrate that allows digging.
- Temperature and Lighting: Provide a basking area at 120°F, with ambient temperatures between 80°F and 90°F. UVB lighting is important for bone health.
- Diet: They are carnivorous and should be fed a diet of insects, rodents, and other protein sources.
Temperament: Savannah monitors can be more laid-back compared to other larger species, but they may be shy or defensive when young. Over time, they can become more tolerant of handling if treated gently.
3. Blue-Tailed Monitor (Varanus doreanus)
Overview: The Blue-tailed monitor is a stunning species with vibrant blue tails, which make it a popular choice among reptile enthusiasts. Native to Indonesia, this species reaches a length of about 3 feet.
Care Requirements:
- Enclosure: A large, vertical terrarium with plenty of climbing opportunities is ideal. An enclosure size of at least 40 gallons is recommended, with larger spaces for adults.
- Temperature and Lighting: The basking area should be around 95°F to 105°F, with a cooler side at 75°F to 80°F. UVB lighting should be provided to promote overall health.
- Diet: They are primarily carnivores, feeding on insects, small mammals, and occasional fruit.
Temperament: Blue-tailed monitors are often more social than other monitors, and with consistent handling, they can become quite tame. However, they do require a lot of stimulation, as they are highly intelligent and active.
4. Argus Monitor (Varanus panoptes)
Overview: The Argus monitor is a large species, reaching lengths of up to 6 feet. It is known for its beautiful pattern and active behavior. While they are not the best species for beginners, experienced owners may find the Argus monitor to be a rewarding pet.
Care Requirements:
- Enclosure: This species requires a very large enclosure, preferably 120 gallons or larger. Argus monitors are highly active and need plenty of space to move around and climb.
- Temperature and Lighting: The basking area should be around 120°F, with ambient temperatures of 85°F to 90°F. UVB lighting is necessary for calcium absorption.
- Diet: They are carnivores, feeding on insects, rodents, and other small animals.
Temperament: Argus monitors can be skittish or defensive, especially when young, but with time and patience, they can become more comfortable with their owners. Their intelligence makes them great pets, but they need a lot of attention.
5. Mertens’ Water Monitor (Varanus mertensi)
Overview: The Mertens’ water monitor is an aquatic species that is relatively small compared to other monitor lizards. It can grow up to 4 feet long, making it an ideal choice for pet owners who want a more manageable monitor.
Care Requirements:
- Enclosure: A large aquatic enclosure with both land and water areas is needed. A 75-gallon tank is suitable for a young Mertens’ monitor, with larger spaces required for adults.
- Temperature and Lighting: The basking area should be around 100°F, with a cooler side at 75°F. UVB lighting should be provided for their overall health.
- Diet: They are carnivores, enjoying a diet of insects, small fish, and other protein sources.
Temperament: Mertens’ water monitors are relatively docile and less likely to be aggressive compared to other species. They are highly intelligent and can become accustomed to handling with time and patience.
General Care for Monitor Lizards
Regardless of the species, monitor lizards share some common care requirements:
Habitat Setup
Monitor lizards are active and require a large, secure enclosure. It’s important to provide:
Climbing surfaces: Branches, rocks, and other structures for climbing.
Substrate: Use a mix of sand, dirt, and coconut husk for burrowing species. Non-burrowing species will need a different setup with clean surfaces and appropriate hides.
Basking spots: These lizards need to regulate their body temperature, so a basking area with a heat lamp is necessary.
Diet and Nutrition
Monitor lizards are carnivores, though some species may eat fruits or plants. A balanced diet includes:
Insects: Crickets, mealworms, and other insects are staples.
Small mammals: Mice or rats can be offered for larger species.
Occasional fruit: Some species, like the Ackie monitor, may enjoy some fruit or vegetables.
Socialization and Handling
Monitor lizards are intelligent and can learn to recognize their owners. However, they can be skittish or defensive, especially when young. It’s important to handle them regularly, but gently, to develop trust.
Conclusion
Monitor lizards are incredible pets for reptile enthusiasts who can provide them with the right environment, care, and attention. The best pet monitor lizard for you depends on your experience, the size of your living space, and your ability to meet their care requirements. Species like the Ackie monitor, Savannah monitor, and Blue-tailed monitor are great choices for both beginner and experienced reptile keepers. With the proper care, monitor lizards can become a rewarding and fascinating pet for any reptile lover.
