A glass terrarium is a container that has been made specifically for the purpose of housing reptiles, amphibians and other small animals. They are usually constructed from clear or tinted glass with an airtight seal to keep moisture in and prevent escape. Glass Terrariums come in all shapes, sizes and styles so you can choose one that fits your needs perfectly.

Glass Terrarium: Frequently asked questions

What types of Glass Terrarium are there and what determines a good product?

There are two types of glass terrariums, the standard and the deluxe. The only difference between them is that one has a built in light fixture while the other does not. Both have an opening on top for easy access to your reptile or amphibian pet as well as ventilation holes at both ends so you can control how much air flow comes into it. They also come with a screen cover which helps keep out bugs and debris from getting inside but still allows fresh air to get through when needed.

The first thing to look for is a good seal. This will keep your terrarium from leaking and losing humidity, which can be very damaging to the plants inside. A glass lid with an airtight fit is also important because it keeps moisture in while still allowing fresh air into the enclosure. Finally, make sure that you have enough space between the top of your substrate and where light enters so that heat doesn’t build up too much on top of your soil layer or cause root rot.

Who should use a Glass Terrarium?

Anyone who wants to keep their reptile in a naturalistic environment. The glass terrarium is ideal for arboreal species such as chameleons, tree frogs and geckos. It’s also great for terrestrial species that require high humidity levels like leopard geckos or desert lizards.

Based on what criteria should you buy a Glass Terrarium?

The first thing you need to consider is the size of your reptile. If it’s a small snake, then you can buy any glass terrarium that suits your needs and preferences. However, if it’s a large python or boa constrictor for example, then I would recommend getting one with an extra-large capacity so they have plenty of room to move around in their enclosure. Another important factor is whether or not the glass tank has been treated with UVB lighting as this will help ensure proper calcium absorption by reptiles such as bearded dragons who require UVB light exposure on a daily basis for healthy bone development.

Some of the most important factors to consider when comparing a Glass Terrarium include its size, weight and material. Make sure you get a full picture by looking at these features in addition to other vital aspects such as price and brand.

What are the advantages and disadvantages of a Glass Terrarium?


Glass terrariums are the most popular reptile enclosures because they allow you to see your pet clearly. They also provide excellent ventilation and visibility, which is essential for keeping reptiles healthy.


Glass terrariums are heavy, fragile and expensive. They can break if dropped or knocked over by a pet. The glass also tends to be very hot in the summer months so you will need to keep it out of direct sunlight during those times.
