Growing Pothos in Aquarium | Everything You Should Know!

Plants in the fish tank benefit the tank environment and the inhabitants. It purifies the water and absorbs the toxic nitrogen resulting from fish waste. That said, pothos inside the aquarium are a good choice as an aquarium plant.

With the help of stem cuttings, pothos plants can be grown inside the fish tank. The plant formation and growth will take at best 3-4 weeks when the conditions are favorable.

This article will cover all the aspects of a pothos plant in an aquarium and guide you through a step-by-step growing process.  So, without waiting any further, let us start.

What Are Pothos Plants?

Pothos are some leafy plants that can be grown both in the wild and indoors. These plants tend to grow long and come with thick and waxy leaves. They have different species that come in different colors.

In addition, if optimum conditions are offered, these can grow very long and require low maintenance.

Growing pothos in the aquarium is possible due to such characteristics. And since it can anchor itself, the growing process involves only setting up the base of the plant.

How to Grow Pothos in An Aquarium?

It is possible to grow pothos in aquariums as these plants are versatile for any conditions. To grow them, there are some specific methods that you need to follow step by step. We have covered two of the most popular and easy methods below. Thus, following the methods may help you grow pothos in your aquarium and make it more lively.

Growing Pothos in Aquarium - how to grow it

Method 1: Use a Stem Piece

The pothos plant grows incredibly long; from there, you can cut a piece of stem to start the process. The steps for this method are listed below:

Step-1: Cut a stem section

Use scissors to cut a stem section around one-foot length from a pothos plant.

Step-2: Remove the leaf around the cut

Once you have taken a stem section from the plant, you’ll notice a node-type part where you cut. From this section, the plant will propagate.

That’s why, if there is any leaf around it, you need to remove it carefully. While doing so, make sure that there is a clean cut so that the plant doesn’t get infected in the aquarium.

Step-3: Put the stem section in water

After you have removed the leaf and other necessary parts, simply put the stem section into the water. As the section has multiple nodes, roots and leaves will come through them when you let the part experience the aquarium environment.

That said, letting the plant section float for at least a week will start the process of pothos growing in the fish tank.

Method 2: Use Suction Cups

Use Suction Cups to Grow Pothos in Aquarium

Using some hooked suction cups, you can initiate the process of pothos growth in the aquarium. The steps for this process are mentioned below:

Step-1: Lower water level

The first step would be to lower the water levels by 6 inches.

Step-2: Route the Pothos

Similarly, like the previous method, you need to route the Pothos plant.

Step-3: Attach to back panel of the Aquarium

Attach the Pothos part on the back panel of the aquarium using the suction cups. This way, you let the root and leaves grow out of the nodes.

Are Pothos Plants Beneficial for Aquariums?

Pothos are some common plants that act as a purifier to a great extent. They can be easily propagated and set up in the aquarium.

Are Pothos Plants Beneficial for Aquariums

That said, these plants can benefit inhabitants inside in various ways. Some of the benefits are listed below:

Reduce Nitrates

The ecosystem of any aquarium will produce nitrates. But when these nitrate levels go higher than the optimum level, it will get more challenging for fishes to exist.

That’s why water changes are required at intervals to lower the level. Plants inside the aquarium are also an excellent option for reducing or removing nitrate. They absorb the nitrates and make the environment more habitable.

Pothos is one aquatic plant with a better absorption rate than most other plants. The reason is that this plant is under water that extracts the nutrients from the water for growth.

Fight Algae Formation

Algae cause many issues to the fish tank, making the appearance dull and habitat challenging. The main reason behind algae formation is the presence of sufficient nutrients and nitrate in the water.

Pothos plant effectively reduces these nutrients as it uses them for its growth. Thus, the risks for algae formation are lowered.

Enhances Appearance

The best part of the Pothos plant is that it gives the aquarium a natural outlook. It improves the fish tank’s appearance and provides the fishes with an identical environment to their natural habitat.

Are Pothos Plants Safe for Fish?

The pothos plants can be toxic to some extent when they are not allowed to heal after cutting. That is why, after cutting, you should keep them in a separate container filled with water.

There the plants would be healed, and when you take them into the aquarium water, there would be no scope for the toxins to spread.


Pothos plants are a superb addition to the aquarium as they enhance the fish tank’s appearance and improve the fish habitat. These plants have one of the highest nutrient absorption rates that help to maintain the optimum level.

But one thing you need to remember while setting them up is not to keep them underwater. Setting the pothos cuttings underwater would minimize all the benefits they offer.

Moreover, these plants require very minimal effort to set up. We have provided a proper guideline for you, and if you feel anything seems missing, do let us know.
