Before You Buy
Key Buying Factors
01
Material Durability
Glass offers excellent scratch resistance and clarity but is heavy and breakable. Plastic and polycarbonate (PC) are lighter, impact-resistant, and easier to drill for modifications, but may scratch over time.
02
Ventilation and Airflow
Proper ventilation prevents condensation and mold. Look for mesh tops, side vents, or adjustable louvers. Enclosures with full-screen tops allow UVB penetration and heat lamp placement.
03
Visibility and Viewing Experience
Full-view glass terrariums provide an unobstructed view from multiple sides, ideal for display. Plastic tanks with clear fronts still offer good visibility but may have fogging issues.
04
Security and Escape-Proofing
Sliding doors, locking lids, and tight-fitting screens are crucial for climbing species and invertebrates. Check that all gaps are sealed to prevent escapes.
05
Ease of Cleaning and Maintenance
Tanks with removable tops or front-opening doors simplify access. Smooth, non-porous surfaces wipe clean easily. Some models have deep bases to hold substrate without spillage.
06
Size and Expandability
Consider adult size of the pet. Small tanks (8"x8"x8") suit tiny geckos or spiders, while larger ones (12"x7"x9") allow for more elaborate setups. Ensure the tank fits your available space and decor.
Living With It
Care, Cost and Maintenance
Cleaning and Hygiene
Spot-clean waste daily. Perform a full deep clean every month using a reptile-safe disinfectant. Remove all decorations and substrate, wash with hot water, and rinse thoroughly.
Temperature and Humidity Management
Use a digital thermometer and hygrometer to monitor conditions. Provide a thermal gradient by placing heat pads under one side. Mist as needed but avoid excessive wetness.
Safety Checks
Inspect all seals, hinges, and screens regularly for wear. Ensure electrical cords from heat sources are secured outside the tank. Never use adhesive tape inside the enclosure.
Pro tip
Always measure your pet's adult size before buying. An enclosure too small can cause stress and health issues. When in doubt, go one size larger.
Frequently asked questions
What size tank do I need for a leopard gecko?
A 10-gallon tank (20"x10"x12") is the minimum for one adult leopard gecko, but a 20-gallon long (30"x12"x12") is better. The tanks we reviewed are smaller, ideal for juveniles or species like dwarf geckos.
Can I use a plastic terrarium for a ball python?
No, ball pythons require larger, more secure enclosures with high humidity. Plastic tanks like the Exo Terra Faunarium are best for small snakes or hatchlings temporarily.
How do I clean a glass terrarium without scratches?
Use a soft cloth or sponge with mild soap and water. Avoid abrasive pads or harsh chemicals. For stubborn stains, a 50/50 vinegar solution works well.
Are PC terrariums safe for tarantulas?
Yes, PC terrariums provide excellent ventilation and are escape-proof when the lid snaps shut. Ensure there are no sharp edges inside.
What is the difference between a terrarium and a vivarium?
A terrarium is a dry or semi-humid enclosure for reptiles or plants, while a vivarium often includes live plants and a drainage layer for higher humidity. All picks here are suitable as terrariums.
