Paludarium: Everything You Need To Know

Let’s explore the marshy vivarium of both water and land.. the paludarium! We will cover what they are, how to make one & the many different types that are popular today. Of all the ariums, this is probably my favorite one and the very cornerstone of why Bantam.Earth was started.

What Is a Paludarium?

A paludarium, also commonly referred to as “paludaria”, is a type of vivarium that consists of both water and land.

The paludal part of the word comes from the Latin word palus, meaning “swamp” or “land near water.” The word itself translates to “a place of swamp or land near water.” The plural form of paludarium is paludaria.

In general, it’s an aquarium with dry terrestrial features. There’s no set law as to how much of it needs to be either aquatic or terrestrial in order to qualify.. The enclosure just needs to consist of both in order to be considered a paludarium.

Paludarium vs. Riparium: What’s the Difference?

Paludaria and riparia are very similar in the sense that they both consist of aquatic and terrestrial features. There is, however, a difference in life sustainability. A paludarium has enough land mass to provide habitable living space for semi-aquatic animals. A riparium has limited land mass but usually cannot support life that depends on “Terra-amenities” (yes – I made up that word).

When discussing ripariums, think of a river bank-type aquarium. More than likely, there won’t be any completely dry areas in this enclosure. The flora will be submersible plants. The animals living in this type of vivarium will be fully aquatic. I go more in depth about riparia here.

Building A Simple Paludarium

Today, I will demonstrate the basic setup of a paludarium. There are three main areas to consider when building this type of vivarium: the canopy, the land and the water. No matter how complex your design is, it should consist of these areas.

Key Features

The Canopy is the topmost area of a paludarium. It’s formed from the planted flora that grows out into the top part of the enclosure. It can consist of hardscape items like branches or rocks. This area provides shade and security for inhabitants living in the land area. This area can also provide a home for animals that prefer to be higher. The higher areas in a vivarium usually provide better basking spots, lower humidity and better air flow.

In the Land portion of the paludarium, the terrestrial features are established. The water portion of the tank is separated by a dry piece of hardscape. The hardscape can consist of just about anything that won’t negatively affect the water conditions. Rocks, soil, wood or even sand are all earthy elements that can form the land part of the enclosure. In some cases, a paludarium may not have a canopy section. Instead, this portion must contain proper basking spots and low humidity levels to allow animals to fully dry off. Semi-aquatic animals thrive in this section of the vivarium.

The Water part of the setup is just that: water! It’s simple yet essential to the thriving ecosystem of a paludarium. This part of the enclosure not only provides living space for aquatic inhabitants, but also the condensation needed to hydrate the top two areas of the tank. This part can also aid in elevating humidity levels within the vivarium.

The Setup

Setting up a paludarium can be simple. Try adding a large piece of floating wood to an aquarium to support an inhabitant. Step it up a notch and separate your tank with acrylic glass, filling the bottom with water and the top with soil. It comes down to the amount of detail and creativity you are willing to put into your enclosure.

different types of paludarium designs

Edens.Bow is a great example of a complex “Floater” paludarium because of the way I chose to layer it and the materials I used to set it up. With this build, you must understand the importance of the key elements working together. Without the proper land mass for inhabitants on which they can establish themselves, this becomes a riparium. If the water section is not equipped to sustain life, this setup is more recognizable as a terrarium.

Converting Other Vivariums

Many hobbyists often start out with some other type of vivarium before later deciding to include additional features that make up a paludarium. Deciding to convert an existing enclosure into a different type of vivarium is common practice. In most cases, modifying the enclosure means adding water to existing land, or vice versa!

Aquarium Conversions

Aquariums are typically the most common vivaria to convert into a paludarium. The pro with using an existing aquarium is simply adding land to your setup. Start by removing water from the tank, allowing more enclosure real-estate to become available for terrestrial features. You can also grow flora out of the top of the enclosure, which will classify your aquarium as a paludarium. The con with using an aquarium: water changes become a bit challenging to do, depending on the setup.

Terrarium Conversions

Terrariums are another common type of enclosure used for conversion. The pro with using a terrarium is that most come with some type of drainage valve at the bottom. Therefore, changing the water is made easier. The con with using terraria is that they’re limited to how much water they can hold. Many are not designed to hold more than a few inches of water without leaks. If a low volume of water is what you have in mind for your terrarium, then this type of conversion will work perfectly.

Best Types Of Plants & Animals

A paludarium is a wet and marshy environment, so keep that in mind when shopping for inhabitants. Stocking proper flora and fauna is ideal if you want a thriving ecosystem. This setup will resemble the shorelines of a rainforest, woodlands or swamp, so plan your livestock accordingly.

Recommended Fauna

You’ll want to stock this enclosure with fully aquatic and/or semi-aquatic species. They should all be animals that can swim!

Aquatic Animals – Any type of freshwater fish will do well in this enclosure. You can even consider a brackish water type of vivarium if you want to go for unique setup. Puffer fish and fiddler crabs are interesting picks to consider! Invertebrates like shrimp or crayfish will also thrive in these types of vivariums.

Semi-Aquatic Animals – Crustaceans like crabs, springtails and pill bugs are excellent for the ecosystem and thrive in the marshy conditions of paludaria. Mud-skippers are cool fish that can actually come out of the water and do well in this setup. Amphibians like frogs, salamanders or newts are the most common species of animals for DIY-ers.

A few honorable mentions that would do well in paludaria are reptiles like turtles, lizards and skinks. Many turtles like sliders and soft shells need both water and land in order survive. Lizards like iguanas and water dragons love basking after a nice swim. When it’s safe to come out and roam, crocodile skinks are known to come out and fish for food.

Recommended Flora

When it comes to plants, aim for flora that thrive in humid and wet environments. This enclosure typically resembles a tropical domain, so keep that in mind when planting. For the water part of your paludaria, choose from emersed or submersed plants.

Terrestrial Plants – These guys can easily be water-bogged if not rooted in a dry enough place above water. The planted area should allow access water to completely drain out during watering and should have a fairly dry or moist top layer of substrate. Common plants used to furnish the land area are Carnivorous Plants, various Moss and Ferns.

 Submersed Plants – This type of plant is completely submerged underwater. Everything from their roots to their leaves are completely under the water. Amazon Sword, Christmas Moss and Java Fern are all good examples of a submersed plant.

Emersed Plants – These plants are rooted underwater but sprout stems and leaves above water. They are both pretty straightforward in terms of setup and care. Your only limit here is the creative vision you have in mind for your theme. Pothos, Hygrophila and Ammania are common examples of an emersed plant.


Choosing a theme is a good place to start when deciding to construct this type of vivarium. The possibilities are endless for aesthetically-pleasing paludaria. I personally have a hard time trying to not make every aquarium or terrarium I build into some type of paludarium.
