Choose The Tank

Imagine, you need to buy a tank for your betta fish. Surely, at that time, you worry about so many features of the tank. But, why? Yes, you need to choose the best tank. 

Here it is also the same. You may have doubts about what are the features that should consist of a tank to prepare a paludarium.

However, there is no exact answer. It depends on what you want to keep in the paludarium tank. So, when you choose a tank for a paludarium, you should consider these factors. 

Animal species You Wish To Rear 

Generally, beginners make common mistakes when selecting a tank for the first time. Before purchasing, they do not think about the fish and other creatures they want to keep in a tank.

But the best thing is, first to think about what inhabitants you like to keep in your paludarium tank. It will help to decide the size of your tank. 

The Layout Of The Desired Paludarium Aquarium 

It would be best to consider the layout you want to set up in the paludarium aquarium.  

If You Wish To Set Up A Waterfall Or Not 

Most hobbyists like to set up a waterfall in their paludarium. So, at that time, you have to decide on enough height and depth to create it. 

Usually, if you like to set a waterfall, you should go for at least 10 gallons tank. Exceptionally, you can set up a small waterfall in a 5-gallon tank too. 

There is no specific tank to create a paludarium. But these are my opinion due to my experience. 

  • If you like to Countertop paludarium,  it is better to select a small aquarium or Nano paludarium tank
  • A small tabletop paludarium is ideal for beginners. Because it is easy to manage at the start-up level. So, you can choose a 5-gallon tank as a beginner. 
  • If you want to set up a larger paludarium, a 50-gallon tank is ideal

The large tanks have plenty of space to create your paludarium and add a diverse collection for it.

Select A Design

Substrate Type

Generally, if you use epiphyte plants, it is not essential to have a substrate. But even so, you can use substrate for aesthetical purposes. 

Here, you can use sand, small rocks, coarse gravels, or crushed lava rocks as a substrate at the submerged part of the paludarium.

Moreover, you can attach or tie the epiphyte plants in driftwoods and rocks. 

Additionally, you can use regular garden soil as a substrate. This substrate is more suitable if you like to go with terrestrial or non-epiphyte plants. But the soil may cause to cloud the water. 

Therefore, you should be highly concerned about isolating the soil part from water. If you do not want to deal with trouble anymore, you can use aqua soil. 

Some hobbyists prefer to grow the Cryptocoryne sp., Amazon Swords, and some Aponogeton sp. In this case, you can use potting or garden soil top with inert Belge or black sand. 

Setting up

First of all, if you are a beginner, starting with a smaller tank is better. Once you have some experience, then you can create a large tank. But it is up to you. 

When creating a paludarium, you must never forget that your layout replicates the natural environment. So, it would be best if you decided everything to achieve that aim. 

Let’s check how to achieve it step by step. 

Step 1: Clear Idea About The Layers Of Paludarium

So, before you set up a paludarium, what are the basic things you should know? Basically, you should think about the layers of the paludarium. Guess! 

  • The canopy 

Simply, the canopy is the top area or layer of the tank. It includes rocks, branches, and tall live plants.

This is the best area for land-dwelling inhabitants because the canopy provides shelters and shade for them. 

  • The land

This area is the ideal place for your terrestrial plants. Further, you should build this area before adding the water.

Also, you can make the land area with rocks, soil, sand, and wood. But basically, it depends on what plants you have to grow in this area. 

  • The water 

The water part is very familiar to you as an aquarist. Because this part resembles the typical aquarium. The water column provides a habitat for all aquatic life.

Also, this part helps to elevate the humidity levels. 

Step 2: Initial Planning 

You should have a plan or mind map about where the land area and water portion you set up in the paludarium. 

Phase 1: Separate the water and land of paludarium

Physically, this is the first thing that you should do when building the setup. There are few different ways to separate the water and the land. Most hobbyists use a divider. 

Generally, a divider makes a barrier to separate these layers. Simply one half of the tank can be water, and another half will be land. 

So, what are these dividers? Most probably dividers are plexiglass because it is safe to use for your paludarium. But you can use any waterproof and aquarium-safe material other than plexiglass. 

Another doubt is, how do you secure the barrier to the tank wall? It is easy with aquarium-safe silicone.

Also, it will help to provide a leak-proof barrier. Moreover, you can use another alternative. But make sure they are safe to your paludarium.

Phase 2: Start to build the land area 

You can use rocks, woods, soil, and sand. If you want to create raises in the land part, you can use upside-down bowls or pots. 

Here, before you add ornaments, think about how hard to remove and cleaning and these things when they trap debris. 

In addition to that, how do you hold these things together? Foam sealant is the solution. Also, it helps to carve into the preferable shape. 

Another important thing is, there should be a drain in the bottom of the land portion. Because it helps to prevent flooding during the water level gets too high.

Phase 3: Plants the suitable live plants 

Here you should select the suitable plants for your paludarium. For instance, decide which plants species can tolerate the proximity of the water portion.

And which plant species can add to the top layer of the paludarium. 

Phase 4: Set up the water portion 

Water portion help to control the humidity. Here, you should concern all elements of a regular aquarium, such as correct water conditions, filtration, etc. 

When comes to filtration, some hobbyist relies solely on live plants for filtration. But on the other hand, some hobbyists use small filters that can submerge.

Another important thing is you should cycle the water before adding animals into the paludarium. 

Phase 5: An in-between area 

This is the best place for terrestrial animals. You can create a floating shelf over the water. Typically, PVC plastic is used to create a shelf.

Also, you can use silicone or aquarium-safe glue to attach to the sides of the tank. On the other hand, supports help to hold the shelf in place. If not, you can use flat pieces of cork or driftwood as alternatives.

Further, as a result of growing moss on this floating shelf, this area provides the foods and substrate for the animals in the tank.

Phase 6: Optional waterfall set in the paludarium

At present, the waterfall is a common feature in the paludarium. It adds additional value to the paludarium. But if you do not prefer to set up a waterfall, you can skip this step. 

Special Note 

After properly cycle the water portion, you can add the animals. However, my recommendation is, before adding any animals, you can take about 14 days to test your paludarium. 

In this time, plants can properly root in and adjust to the enclosure. Also, in this testing time, you can identify some errors. For instance, if you place a plant that does not match, you can quickly move it. 

So, after this testing period, if you are happy with the plants’ growth, lighting, filtration, and heating, you can add your fish and other animals to the paludarium.

But before you select the animals for your Paludarium, you should be aware of what species can be partners. 

So, you can create your collection with the below-mentioned species. 

Freshwater Fish species

  1. Creeping plants and vines – devils ivy and creeping fig  – this plant is ideal for covering the tank’s back walls.
  2. Ferns – boston ferns, holly ferns and lemon button ferns 
  3. Mosses – java moss 
  4. Bromeliads – this species is an ideal addition for frogs, and you can choose them from different sizes

Paludarium waterfall can create by pumping the aquarium water to the top of the waterfall. However, you can use the filter to do this.

 Further, it would be best if you placed the inlet at the top of the waterfall. Additionally, you can build a surface with rocks, woods, and slate to flow down the waterfall.

You need a filter if you wish to rear fish or aquatic invertebrates like snails and shrimps in your paludarium.

Further, if you want to add extra value and beauty to your paludarium, of course, you need a filter.
