Buying Guide
Understanding the Importance of Ventilation
When I look at a terrarium, I look at air exchange. Frogs are highly susceptible to respiratory infections if the air becomes stagnant.
* Look for front-window ventilation; this draws air across the glass to keep it clear.
* Check the mesh material. Stainless steel is preferred over aluminum for longevity in wet environments.
* Ensure there are closable inlets for your wires so you don’t have to leave the top open.
Prioritizing Thermal Management
As an electronics expert, I focus on how the enclosure handles heat. An exo terra frog terrarium is designed with a raised bottom specifically for this reason.
* The gap under the tank allows for airflow, which prevents your substrate heater from overheating and cracking the glass.
* Always use a thermostat with your heating elements to ensure the safety of your frogs.
* Route your sensor wires through the built-in ports to keep the lid flush and escape-proof.
Maximizing Your Budget
You don’t need to buy everything at once, but you should buy the right “skeleton” for your setup.
* Invest in the best glass enclosure you can afford first. Accessories can be added later.
* Resin hides are more cost-effective over a 5-year period than natural wood that rots.
* Look for kits that include backgrounds, as buying these separately can be surprisingly expensive.
Common Questions About Exo Terra Frog Terrarium
Is the Exo Terra Frog Terrarium suitable for bioactive setups?
Yes, absolutely. The waterproof bottom and high front window allow you to add a drainage layer, substrate, and live plants. I’ve found that the glass provides excellent structural support for the weight of wet soil, and the ventilation keeps the plants from rotting.
How do I secure wires in my Exo Terra Frog Terrarium?
These enclosures feature specialized, closable inlets at the back of the screen cover. You simply slide the inlet open, place your heater or sensor wire in the groove, and slide it shut. This keeps the wires organized and prevents even the smallest frogs from finding a gap to escape.
Can I stack multiple Exo Terra units?
While they are sturdy, I don’t recommend stacking them directly on top of each other. The top screen is vital for ventilation and UV light penetration. If you want to save space, use a dedicated shelving unit that allows at least 6 inches of clearance above each tank for lighting and airflow.
How do I clean the glass without scratching it?
I recommend using a soft microfiber cloth and a mixture of distilled water and vinegar. Avoid using razor blades or harsh abrasives, as Exo Terra glass is high-quality but can still be marred by improper cleaning tools. Distilled water also prevents the buildup of hard water spots which can be difficult to remove later.
Does the background come with the terrarium?
In most of the “Kit” models, a natural-looking rock background is included. These are made of high-density polystyrene and provide excellent insulation as well as a textured surface for frogs to climb. They are also designed with channels in the back to hide your wires and tubes.
