How to Plant Pothos in an Aquarium

Imagine having a magical underwater world right in your own home. That’s what aquariums can be. They’re not just pretty decorations, they’re also a chance for you to create a whole ecosystem inside. 

If you want to make it even more beautiful and keep the water clean, you should think to plant pothos in an aquarium.

Pothos plants have lots of beautiful, green leaves and they’re really tough. When you put them in your aquarium, they make it look amazing. But they also do something really important for the health of your aquarium. 

They clean the water and add oxygen to it, which is really good for the fish. Plus, they create a natural home for the fish to live in. If you want to put pothos plants in your aquarium, we’ll explain exactly how to do it step by step. 

That way, you can enjoy all the great things they bring to your underwater world. So let’s get started by first learning about the benefits of having pothos plants in your aquarium!

The Benefits of Pothos Plants in Aquariums

1. Natural Filtration System:

These plants are like natural filters for your aquarium. They have special roots that are really good at sucking up extra food, waste, and dangerous chemicals like nitrates, nitrites, and ammonia. 

When you have Pothos plants in your aquarium, they work hard to keep the water clean and healthy. This means less chance of yucky algae taking over, and your fish and other aquatic friends will be super happy and full of life.

2. Oxygenation and Carbon Dioxide Absorption:

Pothos plants are amazing at making oxygen through photosynthesis. When you have them in your aquarium, they keep pumping oxygen into the water, which is crucial for the well-being of your aquatic friends. 

But that’s not all! Pothos plants also have another important role. They’re excellent at absorbing carbon dioxide from the water. This helps maintain a balanced pH level and prevents harmful gases from accumulating. 

So, having Pothos plants in your aquarium not only adds oxygen but also ensures a healthy and thriving aquatic environment.

3. Natural Shade and Hiding Spots:

Pothos plants have beautiful, flowing leaves that hang down from above the water and also dip below the water’s surface. This creates a natural shade in your aquarium, like a cozy canopy. The shade is useful in two ways: it keeps delicate plants from getting too much light and gives a safe place for shy or timid aquatic animals.

When you have Pothos plants in your aquarium, they make it a comfortable home for small creatures like fish and shrimp. These little animals love to hide in the Pothos leaves whenever they feel stressed or scared. It’s like having their own secret spot, just like they would have in their natural homes.

Adding Pothos plants to your aquarium not only makes it look beautiful but also turns it into a peaceful place. The plants create a safe and cozy environment for both the plants themselves and the animals in the aquarium. With Pothos plants, your aquarium becomes a safe haven where both plants and animals can live happily.

4. Low Maintenance and Easy Propagation:

One of the best things about Pothos plants is how easy they are to take care of. They don’t need a lot of attention and can handle different conditions, so they’re great for both beginners and experienced aquarium lovers. 

Pothos can grow well in different levels of light and can even handle being forgotten about sometimes when it comes to watering. This makes them a perfect choice for people who are busy and may not have a lot of time to devote to aquarium maintenance.

Another great thing about Pothos plants is that they’re easy to multiply. You can easily create new plants by taking cuttings from existing ones. This means you can spread Pothos plants throughout your aquarium or even share them with other people who love aquariums. It’s a great way to build a sense of community and connect with fellow aquarium enthusiasts.

Now that you know the benefits of having pothos plants in your fish tank, let’s discuss the different types of pothos plants that you can put in your aquarium.

Types of Pothos Plants for Your Fish Tank

  • Golden Pothos: The Golden Pothos is the most common and easy-to-find type. It has heart-shaped leaves with a pretty golden-yellow color mixed with green. This plant is strong and can handle different levels of light, which means it can grow well in your aquarium.
  • Marble Queen Pothos: The Marble Queen Pothos has glossy green leaves with creamy-white patterns that look like marbles. These colors create a beautiful contrast, making your aquarium look more attractive.
  • Neon Pothos: As the name suggests, the Neon Pothos has bright, neon-green leaves that add a burst of lively color to your fish tank. This plant can do well even in places with not so much light.
  • Jade Pothos: The Jade Pothos has solid green, heart-shaped leaves. If you want a simple and consistent look for your aquarium, this is a great choice.

Choosing any of these Pothos plants will not only make your fish tank look pretty, but it will also help keep the water clean and provide extra oxygen for your fish to be healthy and happy. Now, let’s learn how to plant Pothos in your aquarium.

1. Selecting the Right Pothos

When you’re choosing pieces of the pothos plant to add to your aquarium, it’s essential to pick ones that are healthy and will do well in water. 

There are different types of pothos to choose from, but the most common one is the Golden Pothos, which is known for its heart-shaped leaves with splashes of golden-yellow color. Another type is called Marble Queen Pothos, which has leaves that are a mix of green and creamy white colors.

To select the right pieces, look for ones with lively and green leaves. This indicates that the plant is receiving enough nutrients and light. Avoid pieces with yellow or drooping leaves because they may not be healthy or get the proper nutrients. 

Also, choose pieces with strong stems that can support the plant as it grows in your aquarium. Fragile or weak stems can easily break, which can affect the plant’s health and appearance.

It’s very important to ensure that the pothos pieces you choose have not been treated with pesticides or harmful chemicals. These substances can harm the fish and other underwater creatures in your tank. 

So, it’s best to opt for organic pieces of pothos or ones that have not been treated with any chemicals for your aquarium. By selecting healthy and chemical-free pothos, you’re creating a favorable environment for your aquatic ecosystem to thrive.

2. Preparing the Cuttings

To prepare your pothos cuttings for planting in the aquarium, follow these simple steps. First, take your pothos cuttings and carefully trim them just below a leaf node. A leaf node is where a leaf grows on the stem. 

This is important because new roots will sprout from this area, helping the cutting to establish itself in the water.

Next, remove any leaves from the bottom half of the cutting. This step is crucial to prevent the leaves from decaying in the water. Decaying leaves can create an unhealthy environment and harm the water quality in your aquarium. 

By removing these lower leaves, you make sure that only the healthy parts of the plant are submerged, reducing the risk of rot or deterioration.

3. Anchoring the Cuttings

To securely position your pothos cuttings, use materials that are safe for your aquatic environment. You can choose from options like suction cups or fishing lines, which won’t harm your fish or other organisms in the tank. Attach the cuttings to the back or sides of the aquarium using these chosen materials.

When positioning the cuttings, ensure that the stem is submerged in the water, while the leaves remain above the waterline. This setup allows the roots to grow and absorb nutrients from the water, supporting the growth and health of the pothos plant. 

Using materials that are safe for the aquarium and placing the cuttings properly, you create a stable environment for the pothos to thrive. The submerged stem allows the plant to get the nutrients it needs, while the leaves above the waterline stay healthy and vibrant.

4. Lighting and Maintenance

To make sure your pothos plant grows well, place your aquarium close to a light source, such as sunlight or artificial lights. Pothos plants need enough light to thrive and stay healthy. 

Sunlight from a nearby window or aquarium lights can provide the light energy needed for the plant to grow. Regularly check the quality of the water in your aquarium. Test the pH level, ammonia, nitrate levels, and temperature of the water. 

It’s important to maintain the right water conditions for both your fish and the pothos plant. If necessary, make adjustments like changing the water or using water conditioners to keep the aquatic environment healthy. 

Watch out for the growth of your pothos plant and trim it when needed. This will help keep its shape, prevent overcrowding, and encourage healthier growth. Trimming excessive leaves and long vines can also prevent the plant from overshadowing other creatures in the aquarium, making the overall look more balanced and attractive.

Once you have successfully planted pothos in your aquarium, something amazing happens. Your fish and the pothos create a special partnership that benefits both of them. 

As the pothos grows and becomes healthier, it helps to improve the overall well-being of your aquarium. This transformation turns your aquarium into a small, beautiful world that resembles a natural ecosystem. It’s truly a sight to behold.


Planting pothos in an aquarium is a wonderful adventure that combines the charm of underwater life with the appeal of vibrant green plants. In our previous discussion, we explored the benefits of having pothos in your aquarium and learned how to plant them.

As you embark on this delightful journey, it’s crucial to provide your pothos plant with the necessary care and attention for it to thrive and prosper. By taking good care of it, you’ll help it reach its maximum growth potential. Thank you.
