Glass terrariums are one of the most common reptile enclosures. The Exo Terra Glass Terrarium is a well-known option with front-opening doors and a mesh top. It comes in many sizes for both ground-dwelling and tree-dwelling species. This review looks at its features, its limits and how to choose the right size.
Verdict at a Glance: The Exo Terra Glass Terrarium is a well-designed glass enclosure with practical front doors, a raised base and closable openings for wires. It’s a good choice for many small and medium reptiles and amphibians. Glass loses heat faster than insulated enclosures, and mesh tops can make humidity harder to hold, so plan your heating and humidity setup carefully.
At a Glance
| Feature | Details |
|---|---|
| Type | Glass terrarium with front doors |
| Sizes | Many sizes, including tall and long versions (check current range) |
| Top | Mesh screen top |
| Base | Raised frame that can fit an under tank heater |
| Extras | Closable wire and tube inlets; lockable doors on many models |
What It Is and How It Works
The Exo Terra has front-opening glass doors, which make feeding and cleaning easier. Many reptiles are less stressed when you approach from the front rather than reaching in from above.
The raised base leaves room for a heat mat below. Closable inlets let you run wires and tubes without leaving gaps. The mesh top lets UVB and heat lamps sit on top.
Glass is easy to clean and lets you see your reptile clearly. However, glass doesn’t insulate well. In cool rooms, you may need more heat. Mesh tops also let humidity escape, so keepers of tropical species often cover part of the top.

Pros and Cons
| Pros | Cons |
|---|---|
| Front-opening doors | Glass loses heat in cool rooms |
| Raised base for heat mats | Mesh top lets humidity escape |
| Closable wire inlets | Heavy, especially larger sizes |
| Many sizes and shapes | Larger sizes can be expensive |
| Lockable doors on many models |
Choosing the Right Enclosure
Before you buy any enclosure, think about what your species actually needs:
| Need | What to check |
|---|---|
| Floor space | Terrestrial species need length and width |
| Height | Arboreal species such as crested geckos need tall enclosures |
| Humidity | Glass and solid-sided enclosures hold humidity better than screen |
| Heat retention | Solid sides and tops hold heat better than mesh |
| Access | Front-opening doors make maintenance easier and are less stressful for many reptiles |
| Lighting | Mesh tops allow lamps to sit outside; check how UVB will reach your animal |
Plan for adult size from the start. Many keepers buy a small enclosure for a baby and upgrade later, but buying the adult-size enclosure first often saves money.
Things to Consider Before Buying
- Choose a size based on your reptile’s adult size.
- Plan how you’ll maintain heat and humidity.
- Check that lamps will fit on the mesh top.
- Consider covering part of the top for humid species.
- Measure your space and floor or stand strength.
Tips for Using It
- Use a thermostat for all heat sources.
- Add background panels to help some reptiles feel secure.
- Check door locks regularly.
Who It Suits
| Good fit if… | Consider something else if… |
|---|---|
| You keep small to medium reptiles or amphibians | You keep a large species that needs a very big enclosure |
| You want easy front access | Your room is very cold |
| You like a clear view of your pet |
Alternatives to Consider
| Option | How it differs |
|---|---|

| Zoo Med Naturalistic Terrarium | Similar front-opening glass design |

Frequently Asked Questions
Is the Exo Terra Glass Terrarium good for leopard geckos?
Yes, in a suitable size. Many keepers use a long, low version for leopard geckos. Choose a size with enough floor space for a warm side, a cool side and several hides.
Is it good for crested geckos?
Tall versions are popular for crested geckos, which climb. Choose a height that allows plenty of climbing branches and plants.
Can I use a heat mat with it?
Yes. The raised base leaves space for a heat mat. Always use a thermostat.
How do I increase humidity?
Cover part of the mesh top, use a moisture-holding substrate and mist as needed. Watch for mold and allow some ventilation.
Does glass block UVB?
Yes. That’s why UVB lamps are placed over the mesh top or inside the enclosure.
Is it escape-proof?
Most models have locking doors. Check that doors close securely and openings are sealed.
How heavy is it?
Larger sizes are heavy. Use a sturdy stand or furniture that can hold the weight.
Can I put two reptiles in one terrarium?
Many reptiles do best alone. Research your species and avoid housing animals together without expert advice.
