What does a reptile terrarium need?
Now that you know how to choose the best model, it’s time to learn about what a reptile terrarium needs. In this section, we will cover the basics of setting up your terrarium.
The first thing you’ll need is a substrate.You can use any type of substrate in your terrarium, but we recommend something that will hold heat well, such as coco coir or lava rock.
Heating and Lighting
Your terrarium will also need some form of heating and lighting. The Exo Terra Glass Terrarium comes with a full-screen top ventilation system that allows for UVB and infrared penetration. You’ll also need to purchase a basking lamp and/or a heat mat, depending on the needs of your pet.
Last but not least, you’ll need some decorations for your terrarium. This can include anything from live plants to fake vines and rocks. Be sure to choose decorations that are safe for your pet and that won’t harm them if they decide to chew on them.
One important factor to consider when setting up your terrarium is humidity. Reptiles and amphibians come from a variety of different habitats, so it’s important to choose the right level of humidity for your pet. If you’re not sure what level of humidity your pet needs, we recommend consulting with a veterinarian or reptile specialist.
There are a few ways to measure humidity in your terrarium. The first is with a hygrometer, which measures the amount of water vapor in the air. The second is with a moisture meter, which measures the amount of moisture in the substrate. And lastly, you can use your skin as an indicator by feeling how dry or damp the air is inside the terrarium.
Heat & Light
Another important factor to consider when setting up your terrarium is heat and light. Reptiles and amphibians come from a variety of different habitats, so it’s important to choose the right level of heat and light for your pet.
There are a few ways to provide heat and light in your terrarium. The first is with a basking lamp, which provides both heat and light. The second is with a heat mat, which just provides heat. And lastly, you can use natural sunlight as your primary source of heat and light. Just be sure to monitor the temperature inside the terrarium.
A thermometer is an important tool that you’ll need to monitor the temperature inside your terrarium. There are a few different types of thermometers, but we recommend using a digital one so that you can get an accurate reading.
You’ll want to place the thermometer in the warmest part of the terrarium, which is usually near the basking spot. Be sure to check the temperature regularly and make adjustments as needed. The ideal temperature for most reptiles and amphibians is between 75 and 85 degrees Fahrenheit.
As we mentioned earlier, decorations are an important part of any reptile terrarium. Not only do they provide your pet with a place to hide and feel safe, but they also help to create a naturalistic environment.Some good options include live plants, fake plants, rocks, and wood. Just be sure to avoid anything sharp or abrasive.
The substrate is the material that you’ll use to line the bottom of your terrarium. There are a variety of different substrates available, but we recommend something that holds heat well, such as coco coir or lava rock.
Be sure to avoid using sand as a substrate, as it can be harmful to your pet if they ingest it. Instead, opt for something that’s more naturalistic and easier on their digestive system. 
How to clean a terrarium?
Cleaning a terrarium is relatively easy, but it does require some regular maintenance. We recommend spot-cleaning the inside of the terrarium every week and doing a deep clean once a month.
To spot-clean, simply remove any waste or uneaten food from the inside of the terrarium. To do a deep clean, you’ll need to remove all of the decorations and substrate from the terrarium and then wash everything down with a mild soap and water solution. Be sure to rinse everything thoroughly before putting it back into the terrarium.
It’s also important to change out the water in your terrarium every week. Simply remove all of the water from the inside of the terrarium and then add fresh, clean water.
Finally, be sure to monitor the temperature and humidity levels inside the terrarium regularly. Adjustments may need to be made from time to time to ensure that your pet is comfortable. 
What reptiles can live together in a terrarium?
One of the great things about reptile terrariums is that they can house more than one reptile. Many reptiles do better when they’re housed with other reptiles.
However, it’s important to do your research before putting multiple reptiles together in one terrarium. Some reptiles are known to be aggressive and may not do well with other reptiles. Others may have different temperature and humidity requirements.
