BUYING GUIDE
Understanding Volume and Thermal Gradients
In my experience, the biggest mistake people make is underestimating how fast a small tank loses heat. Because an exo terra nano terrarium has a high surface-area-to-volume ratio, it cools down quickly.
* Always use a digital thermostat with these tanks to prevent overheating.
* Consider the “Tall” models if your pet spends time off the ground, as heat naturally rises toward the mesh top.
Material Integrity and Security
I have tested the locking mechanisms on multiple brands, and I prefer the Exo Terra spring-loaded latch. It provides tactile feedback that the door is locked.
* The glass is 4mm thick, which is sufficient for thermal insulation but should be handled carefully during cleaning.
* The plastic frames are heat-resistant, but I recommend keeping high-wattage heat lamps at least 2 inches away from the plastic edges.
Common Questions About Exo Terra Nano Terrarium
What are the exact dimensions of the Exo Terra Nano Terrarium?
The standard Nano models come in two primary sizes: the Nano Flat (8x8x8 inches) and the Nano Tall (8x8x12 inches). These dimensions are designed to fit into small spaces like shelving units or office desks while providing enough internal volume for micro-pets.
Is the Exo Terra Nano Terrarium suitable for a Crested Gecko?
I would only recommend the Nano Tall for a juvenile Crested Gecko. Once the gecko reaches adulthood, it will require a larger enclosure, such as the Small Tall or Medium Tall models, to ensure it has enough space for proper exercise and temperature regulation.
Can I use a substrate heater with these glass tanks?
Yes, the design features a raised bottom frame specifically for this purpose. I found that this gap creates a necessary air pocket that prevents heat from cracking the glass, provided you use a thermostat to regulate the temperature of the heating mat.
Is the mesh top on the nano series rust-proof?
The mesh is made of high-quality stainless steel, but it is not completely immune to corrosion if exposed to high salinity or constant moisture without airflow. I recommend wiping down the mesh once a week if you use a misting system to prevent mineral buildup.
Does the nano tank come with a background?
Yes, most kits include a rock-textured foam background. I find this background useful for hiding wires and providing a climbing surface, though I recommend checking behind it periodically to ensure no small feeders or pets have squeezed into the gap.
