Before You Buy
Key Buying Factors
01
Size & Species Fit
Choose floor space over height for terrestrial species like bearded dragons; taller tanks for arboreal species. Our picks range from 10 to 120 gallons.
02
Door & Access
Front-opening doors reduce stress and simplify cleaning. Double doors with magnetic or latch closures offer best access.
03
Material & Build
Glass tanks retain heat and humidity better than plastic. Tempered glass is safer; check for reinforced corners.
04
Ventilation
Screen tops allow UVB and heat lamp placement. Some glass tanks have side vents for cross-flow; crucial for high-humidity species.
05
Assembly & Setup
Many require partial assembly. Models with silicone-sealed edges are more escape-proof but harder to modify.
06
Ease of Cleaning
Removable top screens and smooth interior surfaces simplify maintenance. Look for removable bottom trays or sliding doors.
Living With It
Care, Cost and Maintenance
Temperature Gradient
Provide a basking spot at one end and a cooler zone. Use thermostats and digital sensors; check daily.
Humidity Management
Mist or use foggers for tropical species; monitor with hygrometer. Ventilation adjustments help control levels.
Substrate & Cleaning
Choose species-appropriate substrate (e.g., coconut fiber, reptile carpet). Spot clean daily, deep clean monthly with reptile-safe disinfectant.
Pro tip
When assembling a glass terrarium, use a silicone sealant on interior seams before adding substrate to prevent moisture damage and improve insulation.
Frequently asked questions
What size terrarium do I need for a bearded dragon?
Adult bearded dragons require a minimum 75-gallon tank; a 4x2x2 ft (120-gallon) is ideal for ample floor space.
Can I use a fish tank as a reptile terrarium?
Yes, but ensure a screen top for ventilation and UVB/heat lamps. Aquariums often lack front-opening doors, making maintenance harder.
How do I clean a reptile tank without harming my pet?
Remove your reptile, spot clean with a reptile-safe cleaner, rinse thoroughly, and allow to dry before reintroducing.
Do I need a special light fixture for a glass terrarium?
Most screen tops can hold UVB and heat lamps. We recommend a dual fixture with a reflector to maximize output.
How often should I replace substrate?
Spot clean daily; replace entirely every 2-4 weeks for non-bioactive setups. Bioactive enclosures need less frequent full changes.
