How To Plant Pothos In Aquarium

You can plant pothos in aquarium simply by placing the cuttings in the water with the leaves above the surface.
 
This is one of the easiest ways to add live greenery to your tank and it works beautifully.
 
Many aquarists do plant pothos in aquarium to help control nitrates and give fish a more natural environment.
 
In this post, we’ll walk through exactly how to plant pothos in aquarium, what you need, and how to keep it thriving.
 
Let’s dive right in.
 

How to Plant Pothos in Aquarium

The process of how to plant pothos in aquarium is straightforward and beginner-friendly.
 
Here are the key steps to follow when you want to plant pothos in aquarium for the first time.
 

1. Choose Healthy Pothos Cuttings

Start with a healthy pothos vine that has several leaves and visible nodes.
 
Nodes are the small brown bumps along the stem where roots will emerge.
 
You only need a cutting with three or four leaves to successfully plant pothos in aquarium.
 
Remove the lower leaves so only the top leaves remain above the waterline.
 
This prevents rotting and keeps the cutting focused on rooting.
 

2. Rinse and Prepare the Cuttings

Before you plant pothos in aquarium, rinse the cuttings under lukewarm water to remove any dirt or pests.
 
If the cutting came from a potted plant, shake off all soil from the roots.
 
You don’t want any soil entering your aquarium because it can cloud the water.
 
Trim any damaged or yellowing leaves so the plant can direct energy into new growth.
 

3. Place the Cuttings in the Aquarium

Now comes the actual moment when you plant pothos in aquarium water.
 
Simply insert the stem so that the nodes are submerged but the leaves stay completely above the water.
 
You can use the aquarium lid, filter intake, or a suction cup basket to hold the stems in place.
 
Make sure the leaves aren’t underwater because pothos leaves will rot if fully submerged for long.
 
Within a week or two, you’ll see white roots growing from the nodes.
 

4. Let the Roots Establish

After you plant pothos in aquarium, give the roots time to grow and anchor.
 
Don’t move or disturb the cuttings during the first two weeks.
 
The roots will absorb nutrients directly from the water, helping to reduce nitrates and waste.
 
This is why so many fish keepers choose to plant pothos in aquarium as a natural filter.
 

Best Conditions When You Plant Pothos in Aquarium

To get the best results, you need to provide the right environment after you plant pothos in aquarium.
 
Here are the conditions that help pothos thrive in an aquarium setup.
 

1. Adequate Lighting

Pothos needs moderate indirect light to grow well in an aquarium.
 
If your tank has a light, place the pothos so the leaves receive that light but not direct scorching sun.
 
Low light slows growth, while bright light encourages faster leaf production.
 
You can also supplement with a small LED clip light aimed at the leaves.
 

2. Temperature and Water Quality

The water temperature in the aquarium should stay between 70–82°F (21–28°C) for best growth.
 
Pothos is tolerant, but if you plant pothos in aquarium with very cold water, root development stalls.
 
Keep the water clean and well‑circulated so roots get oxygen.
 
Avoid using medications with copper, as copper can harm pothos roots.
 

3. Nutrient Availability

When you plant pothos in aquarium, the plant feeds on fish waste and leftover food.
 
That means you rarely need to add fertilizer for the pothos.
 
However, if you have a very lightly stocked tank, you can add a few drops of liquid aquarium plant fertilizer.
 
Too many nutrients can cause algae, so let the pothos do the work first.
 

Common Mistakes When You Plant Pothos in Aquarium

Even though it’s simple, some mistakes can stop your pothos from thriving.
 
Here’s what to avoid when you plant pothos in aquarium.
 

1. Submerging the Leaves

The most common error is putting leaves underwater when you plant pothos in aquarium.
 
Pothos leaves cannot survive long periods submerged – they will turn yellow and rot.
 
Always keep the foliage above the waterline, even if the roots are fully immersed.
 

2. Using Unwashed Soil Roots

If you transfer a potted pothos into the aquarium, wash the roots thoroughly.
 
Soil left on the roots will cloud the water and may introduce bacteria or pests.
 
Rinse until the water runs clear before you plant pothos in aquarium.
 

3. Overcrowding the Tank

Pothos can grow very fast once established, so don’t plant too many cuttings at once.
 
If you plant pothos in aquarium too densely, the roots can clog filters or take over the tank.
 
Start with one or two cuttings, and trim them regularly as they grow.
 

So, How to Plant Pothos in Aquarium?

You can plant pothos in aquarium by taking healthy cuttings, rinsing them, and placing the stems in the water with leaves above the surface.
 
It’s that simple – and the benefits are huge for water quality and tank aesthetics.
 
Just remember to use indirect light, keep leaves dry, and let the roots do their job.
 
Now you know exactly how to plant pothos in aquarium and keep it happy for years.
 
Happy planting.
