By Sarmistha Banerjee Updated

Paludarium is a tank where you can keep aquatic plants, amphibians, terrestrial animals, and fish. You may have enjoyed the experience of fishkeeping, but have you tried to expand your hobby? Keeping terrestrial animals and amphibians such as crabs, shrimps, frogs and turtles in your tank may also bring an interesting dimension to your hobby like the diversion of fishkeeping. Now, you can enjoy that hobby by keeping terrestrial and aquatic life in the same tank using a divider that separates the land and water.

Overview

A paludarium is a semi-aquatic habitation where water and land work together for creating a natural ambiance. You can keep both animals and plants in this tank. There is enough space to keep animals that live in the land. There is an enclosure part where you can add aquatic fish and other species. This habitat replicates wetlands, rainforests and streams. The word ‘Paludarium’ comes from a Latin word, ‘Palus,’ which means marsh or swamp, and ‘arium’ means a location or a container. You may also have heard about other tanks such as Vivarium and Terrarium. Let us know the differences between the three tanks:

  • Paludarium: It is an aquarium where you can keep both terrestrial species and aquatic plants by dividing the tank.
  • Terrarium: It is a dry low-humid tank where you cannot keep any aquatic animals. You can only keep plants in this tank.
  • Vivarium:You can keep only reptiles and amphibians in this tank.

How to Set Up a Paludarium?

A simple aquarium set up process is not followed while setting a paludarium because of the terrestrial and aquatic plants and inhabitants’ dwell in a paludarium. So, you need to provide both land and water part in this tank.

You need to create a natural ambiance in the tank, which is comfortable for both terrestrial and aquatic animals. You can buy small, medium or a large tank to build a paludarium. It is necessary to set up layers and canopy of land and water for different types of species and plants.

The canopy is the topmost area of the paludarium that includes rocks, plants, and branches. The land-dwellers or terrestrial species live in the canopy area. This area is built before adding water to the tank. The water part of the tank is like an aquarium, which is the home of the aquatic animals and plants.

Steps to Build Up a Paludarium

It will be easy to set up a paludarium if you follow some steps to create land and water part in the tank separately. Go through the steps to build the tank:

1. Separate the Land and Water by Using a Divider

Use a divider to create a barrier in the paludarium. The half portion of the tank should have water, and the other half portion should be ornamented with soil substrate, driftwood, pots, caves, rocks or sand. The dividers are made of plexiglass and they are safe to be used in the tanks. Secure the divider of the land and water by using aquarium silicone on the tank wall that will provide a leak-proof barrier.

Always build the land portion above the water level. The land portion is ideal for keeping terrestrial plants and animals like crabs, frogs and reptiles. Keep aquatic species such as fish, snails, shrimps and aquatic plants in the aquatic part of the paludarium. Check the temperature, pH level and hardness of the water while adding the aquatic species and herbs in the tank.

2. Build Up a Floating Shelf Over the Water

You can use PVC plastic to create a floating shelf. Use silicone or an aquarium glue for adhering to the corners of the tank. Try to use a support to hold the shelf. Use flat pieces of cork or driftwood alternatively. This floating-place is perfect for keeping turtles.

3.  Set the Plants in the Aquatic Portion and the Land Part

After keeping the aquatic and terrestrial inhabitants in the tank, your tank is ready to be ornamented with aquatic and terrestrial plants. Enhance the eco-friendly environment in your tank by keeping ideal plants in the tank. Before planting any herb, keep appropriate substrate and driftwoods in the paludarium.

4. Add Filter and LED Light in the Paludarium

Filters are needed in the aquatic portion of the tank to flush out the waste elements and maintain the quality of the water. The light is required for both the land and the water portions because most of the inhabitants don’t like living in a dark tank. Some paludariums are found with kits and you need to buy the filters and lights for those tanks which are empty.   

5. Decorate the Paludarium

As we know that both the aquatic and terrestrial species live in this tank, so you need to decorate it specially. Keep rocks, caves, sand/soil, plants on the land portion. Arrange fine gravels, fish caves, ceramic pots, and aquatic plants in the aquatic part of the tank.

The above steps will help you set up the paludarium appropriately. If you are a beginner aquarist and you want to build a paludarium, then definitely the ideas described above will help you.

How to Clean a Paludarium?

It is not tough to maintain the hygiene of a paludarium. You have to give some more time to clean this tank. You can do it once a week. Take a look at a few ways of cleaning a paludarium:

1. Clean the Land Portion of the Tank

Firstly, clean the land portion of the paludarium by trimming the dead leaves of the plants. After trimming the leaves, use a siphon to clean the rocks and the ground of the land portion. While cleaning the tank, keep the terrestrial species in another tank. Once the cleaning process is over, keep them back in their tank.

2. Cycle the Water of the Aquatic Part and Clean the Aquarium Portion

Cycle the water of the tank to break down nitrate and ammonia. This process will also help in killing harmful bacteria. Replace 10% water in a week and 20% water in a month. Use gravel cleaner to clean the gravels in the tank. You can use liquid soap and a soft brush to clean the walls and decorations of the tank. After the replacement process, check the temperature, hardness and pH level of the water before setting a new batch of water.

During the cycling process, keep the fish and other aquatic species in a separate tank. Regular cleaning and replacement may annoy the fish, so water cycling is preferred to be done once in a month, and a 10% water replacement can be done in a week.  

We hope you have got a lot of ideas in setting and cleaning a paludarium. If you have never made this type of tank before, then now you can definitely set a paludarium and keep both the terrestrial and aquatic species together in the same tank by dividing them.
