Before You Buy
Key Buying Factors
01
Size & Space
Ensure the tank provides adequate floor space and height for your reptile species. We recommend at least 20 gallons for most lizards and snakes.
02
Security & Locks
A secure lid or lockable door prevents escapes. Look for sliding doors with sturdy latches or mesh tops with clips.
03
Heating Compatibility
Under-tank heaters must match the tank size and material. Glass tanks work best, but ensure the heater is UL listed and has a thermostat.
04
Ventilation
Good airflow prevents mold and regulates humidity. Mesh tops or screened sections are essential, but avoid drafts.
05
Accessibility
Front-opening doors make feeding and cleaning easier. Top-opening tanks can stress shy reptiles and are harder to maintain.
06
Material Quality
Glass tanks should be tempered with smooth edges. Avoid acrylic for high-heat setups as it warps. Check for scratches or cracks out of box.
Living With It
Care, Cost and Maintenance
Temperature Gradient
Create a warm side (88-92°F for most desert species) and a cool side (75-80°F). Use a thermostat to regulate under-tank heaters and avoid burns.
Humidity Control
Mist the enclosure as needed for your species. Use a hygrometer to keep levels within 30-50% for arid reptiles. Over-misting can cause respiratory issues.
Cleaning Schedule
Spot clean waste daily. Disinfect the entire tank monthly with a reptile-safe cleaner. Rinse thoroughly and let dry before reintroducing your pet.
Pro tip
When using an under-tank heater, always pair it with a thermostat to prevent overheating. Stick-on heat mats should cover about one-third of the tank floor.
Frequently asked questions
Can I use a fish tank as a reptile enclosure?
Yes, but you must modify the lid for ventilation and secure it to prevent escape. Fish tanks also lack front-opening doors, making maintenance harder.
What size tank do I need for a leopard gecko?
A 20-gallon long tank is recommended for one adult leopard gecko. Larger is better for enrichment. Our picks at 50 gallons offer ample space.
Are under-tank heaters safe for all reptiles?
They are safe for ground-dwelling species that need belly heat. Arboreal reptiles may benefit more from overhead heat lamps. Always use a thermostat.
How do I clean a reptile tank without chemicals?
Use a 3% bleach solution (1 part bleach to 10 parts water) or a reptile-safe cleaner. Rinse thoroughly with water and let air dry before use.
Do front-opening tanks keep humidity better?
Yes, because they have less mesh area. However, this can lead to high humidity if not ventilated properly. Monitor with a hygrometer.
