Lizards are popular reptile pets. They are interesting to watch and come in many shapes, sizes, and colors. But to keep them healthy and happy, they need the right environment. A lizard tank is where your lizard will live, eat, sleep, and explore. Creating the right lizard tank is very important for your pet’s well-being.
This guide will help you understand how to choose the right tank, what to put inside it, and how to maintain it.
What Is a Lizard Tank?
A lizard tank is a type of enclosure designed to house lizards. It is also called a terrarium. The tank provides your lizard with space to live and gives you a way to control its temperature, humidity, and lighting.
Lizards come from different environments like deserts, forests, and tropical areas. A good lizard tank should copy the lizard’s natural habitat.
Choosing the Right Size Tank
Tank size matters a lot. Lizards need enough space to move around. The size of the tank depends on the size and type of lizard.
Here are some general rules:
- Small lizards like geckos or anoles need a tank that is at least 10 to 20 gallons.
- Medium lizards like bearded dragons or blue-tongue skinks need at least 40 to 75 gallons.
- Large lizards like iguanas may need a tank that is 120 gallons or larger.
If your lizard likes to climb, choose a tall tank. If it likes to dig or run, a longer tank is better.
Types of Lizard Tanks
There are different types of lizard tanks. Each has pros and cons.
1. Glass Tanks
These are the most common. They allow you to see your lizard clearly. They are easy to clean but may not hold heat or humidity well.
2. Plastic Tanks
Lightweight and cheaper than glass. They hold heat better but may scratch easily and are not as clear.
3. Wooden Enclosures
These are good for large lizards. They are sturdy and hold heat well. But they are heavy and can be harder to clean.
4. Screen Cages
These are great for lizards that need lots of air circulation, like chameleons. But they are not good at holding in heat or humidity.
Choose a tank based on your lizard’s needs.
Lid and Ventilation
All lizard tanks need a secure lid. Lizards are good at escaping. The lid should allow air to pass through but keep your pet safe inside.
A screen top is a good choice because it offers ventilation and a place to put heat lamps.
Temperature and Heating
Lizards are cold-blooded. They need heat to digest food and stay active.
You must create a temperature gradient. One side of the tank should be warm (basking area) and the other side cooler.
Basking Area:
- Use heat lamps, ceramic heat emitters, or under-tank heaters.
- The basking area should be around 90°F to 110°F, depending on the lizard.
Cool Area:
- Keep the cool side around 70°F to 85°F.
Always use thermometers on both ends of the tank. Check temperatures daily.
Lighting for Lizards
Most lizards need UVB lighting. This helps them make vitamin D3 and absorb calcium. Without UVB, lizards can get very sick.
- Use a UVB bulb made for reptiles.
- Keep the light on for 10 to 12 hours a day.
- Replace UVB bulbs every 6 to 12 months, even if the light still works.
Some lizards also benefit from UVA light, which helps with mood and activity.
Humidity and Misting
Humidity is the amount of moisture in the air. Some lizards need dry tanks, and others need humid tanks.
Desert Lizards:
- Like bearded dragons, they need low humidity (20% to 40%).
Tropical Lizards:
- Like green anoles or chameleons, they need high humidity (60% to 80%).
Use a hygrometer to measure humidity. You can increase humidity by:
- Misting the tank with water.
- Using a fogger or humidifier.
- Adding live plants or moist substrate.
Substrate: What Goes on the Tank Floor?
The substrate is the material that covers the bottom of the tank. It affects cleanliness, humidity, and comfort.
Here are some substrate options:
For Desert Lizards:
Reptile carpet: Easy to clean.
Paper towels or newspaper: Cheap and safe.
Calcium sand: Only use if your lizard does not eat it. It can cause impaction.
For Tropical Lizards:
Coconut fiber: Holds moisture well.
Orchid bark: Good for humidity.
Soil mixes: Must be chemical-free.
Avoid cedar or pine shavings. They are toxic to reptiles.
Hides and Decor
Lizards need places to hide and explore. These help reduce stress and make the tank feel natural.
Add these items:
Hiding spots: One on the warm side and one on the cool side.
Climbing branches or rocks: For arboreal lizards.
Basking rocks or logs: Under the heat source.
Live or fake plants: For decoration and cover.
Change the setup sometimes to keep your lizard interested.
Feeding in the Tank
Feeding your lizard in its tank is common. But be careful to remove uneaten food quickly.
Use a shallow dish for worms or chopped veggies. For insects like crickets, don’t leave them in the tank too long. They may bite your lizard.
Dust insects with calcium powder to keep your lizard healthy.
Water Bowl and Hydration
Lizards need fresh water. Place a shallow water bowl in the tank. Change the water daily.
Some lizards, like chameleons, won’t drink from bowls. They prefer water droplets. You can mist the leaves or use a dripper system.
Cleaning and Maintenance
Keep the tank clean to prevent illness.
Daily Tasks:
- Remove poop.
- Change water.
- Check temperature and humidity.
Weekly Tasks:
- Clean food and water bowls.
- Wipe down tank surfaces.
Monthly Tasks:
- Remove and replace substrate.
- Deep clean the entire tank with reptile-safe cleaner.
Best Lizards for Beginners and Their Tank Needs
Here are a few lizards that are great for beginners:
| Lizard | Tank Size | Humidity | UVB Needed? | Notes |
|---|---|---|---|---|
| Leopard Gecko | 20 gallons | Low (30%-40%) | Yes | Likes to burrow and hide. |
| Bearded Dragon | 40+ gallons | Low (30%-40%) | Yes | Needs a hot basking area. |
| Crested Gecko | 20 gallons (tall) | High (60%-80%) | Yes | Likes to climb, no heat lamp needed if kept warm. |
| Blue Tongue Skink | 40+ gallons | Medium (40%-60%) | Yes | Needs space and soft substrate. |
Common Mistakes to Avoid
- Using the wrong type of heat or light.
- Not measuring temperature or humidity.
- Using unsafe substrates like sand for young lizards.
- Keeping multiple lizards together in one tank (unless you are sure it’s safe).
- Ignoring signs of stress like not eating or hiding too much.
Signs of a Healthy Lizard
- Eats regularly.
- Has clear eyes.
- Sheds skin completely.
- Is active and alert.
- Poops regularly and normally.
If your lizard looks sick, take it to a reptile vet.
Conclusion
A lizard tank is more than just a box. It’s your pet’s world. Whether you’re setting up a home for a gecko, dragon, or chameleon, the tank should meet their needs for heat, light, humidity, and space.
Choosing the right tank, substrate, decorations, and equipment is the first step to raising a healthy, happy lizard. Keep things clean, stay consistent, and enjoy watching your little reptile thrive.
Lizard tanks come in many shapes and sizes. No matter which you choose, make sure it matches the lizard’s natural habitat. A well-designed tank makes life better for your pet and easier for you.
