Tarantula Tank Guide: Everything You Should Be Doing

Tarantulas are wild insects, who love to live in their natural habitat. So, if you are keeping Tarantula as a pet, you need to put in some effort to provide a good home for them and today we talk about Tarantula Tank.

Keeping their comfort in mind, you also need to make sure that the tank won’t allow your pet to escape. While it should be ventilated, it should not have an opening large enough to let them pass.

So, as a tarantula owner, you need to know the basics of creating and maintaining a house for your little pet.

So in this guide, we share about creating and maintaining a Tarantula Tank.

Tarantula Housing

Most people like to keep their tarantulas in a fish tank or terrarium. For the top, the best option would be to provide a locking mesh screen top.

This would allow enough ventilation for your pet and at the same time, stop it from escaping. As for the size of the tank, it should be large enough to allow them free movements, but not enough to take up half your room.

A five to ten-gallon tank is more than enough for a tarantula. It should provide your pet with enough space for movement and you can also decorate it.

Temperature and Humidity

This is exceptionally important when it comes to maintaining a Tarantula tank. Most tarantulas come from hot and humid regions, so they are most comfortable in that environment.

You can keep the tank warm by placing a heating pad on the bottom of the tank. The temperature in the tank should be between 70 to 80 degrees Fahrenheit. As for the humidity, it should be around 60 to 90 percent.

Remember that tarantulas would easily get dehydrated in low humidity. Not only that, their abdomen will start showing wrinkles. And the worst part is that they can’t molt in an environment with humidity of less than 60 percent.

One of the easiest ways to keep the humidity up is to provide good ventilation and use moist soil for tropical species.

You can also use a humidifier if you live in cold and dry regions. However, you don’t need to worry too much about the humidity if you are from a hot and humid place.


Substrate refers to a surface or material on which an organism lives, grows, and obtains its nourishments.

Choosing a substrate for the tank is yet another factor, as it would depend on the species of the tarantula.

The most common options available are peat moss, horticultural vermiculite, potting soil, and crushed coconut fiber.

Tarantula Tank Habitat

A substrate cannot be too hard or rough, so it won’t hurt the tarantula’s skin. You can provide a 3 to 7 cm thick layer inside the tank.

However, for terrestrial species, a maximum of 15 cm thick layer may be required. Substrates are easily available at garden centers. You have to always keep the substrate damp to up the humidity levels in the tank.


Tarantulas don’t usually like to live in bright places, and they particularly hate direct sunlight.

The normal amount of light you have in your room should be enough for them and it certainly won’t be an issue if you turn off the lights.

However, if you like to see your pet in a dark room, you can add a dim light, preferably red, inside the tank. However, the light should not be enough to dry out the humidity level.


Tarantulas won’t normally dirty the tank. Even their excretion is a quick-drying fluid that is odorless. So, you don’t need to maintain a certain schedule to clean the Tarantula tanks. As long as you feel like the tank looks dirtier than before, you can clean it.

However, it is still a good idea to completely clean every 4 to 6 months. For that, you should also replace the substrate.

Tarantulas are extremely popular nowadays as pets. However, before you buy one, you need to know that taking care of them isn’t the same as taking care of dogs or cats.

Though tarantulas don’t require meticulous and serious care, they do have very different requirements. So, before you decide to buy one, try to find out more about the requirements and the natural habitat of the species you are planning to pet.

Also, it would be recommended to know the age and gender of the tarantula.
