Benefits Of Pothos Plant In Aquarium

Keeping your home decor looking sharp is possible with an aquarium. They may serve as a focal point in any environment and are stunning to look at. However, adding pothos to an aquarium has a lot of extra advantages. Here are several benefits of including this plant in your aquarium.

Benefits Of Pothos Plant In Aquarium

Removes Algae

Aquarium algae may be a tremendous headache for any fish keeper. It indicates a nutritional shortage and signifies that the aquarium receives excessively light or has high nitrate content.

Pothos plants will progressively minimize algae development since they effectively extract nitrates from the water. Pothos plants might help to remove algae in your aquarium over time.

Give Protection

Fish and eggs are shielded by the pothos plant’s substantial and deep root system. Pothos roots are also perfect for blocking the line of vision in the aquarium, allowing fish to readily hide between roots.

These roots give places for larvae and fish to create homes and shelter. The plant provides ideal, cozy spaces for the fish to reproduce and lay eggs. Furthermore, the large Pothos plant leaves make an excellent resting location.

Take Nitrates Out

This plant is renowned for its nitrate-absorbing properties, much like all other freshwater fish tank plants. However, the Pothos absorbs nitrates at a rate that is 20 to 40 ppm higher than that of other plants.

When the nitrate concentration of the water increases, your fish may become ill and possibly die. To counteract this, use a Pothos plant in the tank.


Pothos plants help the tanks oxygenate on the run smoothly. The fish’s produced carbon dioxide has been utilized by the plants during photosynthesis, which oxygenates the aquarium in exchange.

And when it concerns fish survivability and fertility, oxygen is a critical component.

Builds A Natural Environment

The overwhelming majority of aquatic species of fish choose to continue with their regular routines. To mimic their habitat, it is essential to arrange the aquarium.

Adding some Pothos plants might aid in recreating your fish’s natural behavior. And it is crucial for the fish in the aquarium to survive.

Types Of Pothos Plant Grow In Aquarium

Different leaf colors of the Pothos plant can enhance the appearance of your aquarium. Let’s figure out which kind is more prevalent.

Cebu Blue Pothos

This houseplant’s variety’s leaves are not variegated. The leaves are mostly colorful and arrow-shaped. Therefore, if the plant is nurtured under ideal circumstances for any period, it can develop broad leaves.

Marble Queen Pothos

Beautifully patterned leaves of Marble Queen Pothos seem more creamy than green in hue. This deeply varied plant grows slowly and needs bright, indirect sunshine.

Devil’s Ivy

The classic kind of Pothos, which has deep green cardio leaves, is called Jade Pothos or Devil’s Ivy. These Pothos plants are elementary to maintain.

Jade Pothos stems can reach a length of three feet. This plant may be grown in tanks and is suitable for use as a hanging or swinging plant. They can survive in environments with high moisture and little sunshine.

Manjula Pothos

The University of Florida owns the patent for this cultivar. It features heart-shaped patterned leaflets.

In the center are colors such as pale green, silver, white, and cream. The petals are diverse, though; some will have sizable green areas and others will seem splattered.

Golden Pothos

These Pothoses have leaves that have a yellow variant allele with light lime color. It is one of the most well-liked varieties of swinging basket plants. The shaded leaf designs resemble elegant brushstrokes and lend a delicate appearance to any uninteresting area. This particular kind of Pothos is a light-tolerant air-purifying plant that NASA recommends keeping in every household.

Neon Pothos

Choose this variety if you want a plant with vibrant foliage. The heart-shaped leaflets of the Neon Pothos are primarily golden yellow in hue. Younger neon Pothos is more dynamic than older ones as the color naturally intensifies with age.

Ensure the Pothos is clean and free of brown, sick areas on the leaves or tendrils. Take the plant out of the pot and wash it well to eliminate impurities like dirt and insecticides.

Trim The Roots

Generally, Pothos roots are matted and knotted when you remove them from the container. As much as possible, shape up, and shave the muddy areas. In the tank, the roots will grow more firmly.

Put The Pothos In The Tank

Place the plant in the water with the branches above the surface and the roots below. The plant will die if the petals are submerged in water.

The Pothos will require approximately a month to properly develop themselves in the tank. It is thus quite natural if they don’t generate any new leaves during this period.

How To Take Care Pothos Plant In Aquarium?

Even though the Pothos are easy to cultivate and maintain, they need a particular combination of circumstances to flourish. What are the optimum circumstances for this companion of the fish keeper? Let’s go over them one at a time.

How To Take Care Pothos Plant In Aquarium


Indirect lighting, which is neither excessively intense nor too faint, is ideal for Pothos plants. Therefore, situate your tank in a well-lit area instead of a dim nook.

You may even use a neon bulb to fulfill the illumination demands of your Pothos in the tank. It is recommended to situate your aquarium in an area with dim or indirect lighting. Pothos in water media responds amazingly to ambient or artificial lighting.

Water Supply

In a water medium, Pothos is hardly submerged or overwatered. First, check to see that every root is thoroughly immersed in water. If you notice that the water seems muddy, replace it periodically.


As a tropical plant, the pothos can withstand a wide range of temperatures. For water-rooted Pothos, a temperature range of 70 to 90 degrees Fahrenheit is optimum. Your Pothos won’t have any temperature issues as far as your tank is inside.

Common Problems With Pothos Plant In Aquarium

Without question, the most attractive feature of your fish tank is aquatic plants. But what happens if these lovely flowers begin to decay and wilt? So consider the potential reasons your Pothos can pass away and a few treatments for each.

State Of The Light

Tank plants needs light to carry out photosynthesis, just like all other plants do. As a result, the nutrition in the water is insufficient on its own. Inadequate light is one of the leading causes of aquarium plants dying.

Possible Solution

  • The optimum lighting is indirect light. As a result, put your aquarium somewhere that gets some light.
  • You should spend money on an excellent fluorescent bulb that generates a wide range of colors if your residence is dark. It will support the survival and growth of your aquatic plants.
  • You would not expect this, but the hue of the light also has a significant impact. Aquatic plants like a color intensity ranging from blue and violet or between the two.


For the fish tank to stay healthy and fresh, filtering is a crucial component of an aquarium. Nevertheless, it occasionally causes aquarium plants to die by absorbing all the carbon dioxide.

The filters work brilliantly for the fish but less well for the plants. Since then, blowers for carbon dioxide have been placed in many fish tanks. The cleaners are to reason if your photos aren’t doing correctly despite your best efforts! Sometimes too much filtering might be detrimental.

Possible Solution

  • Get a filter for carbon dioxide for your fish tank.
  • Ensure the tank plants receive their daily carbon dioxide dosage without adversely affecting your fish pets.

Water Form

Have you ever thought of having your tap water analyzed? If not, you might want to do that for the health of both you and the tank plants. Your fish and Pothos are at risk if your water supply has excessive levels of nitrates and ammonia.

The silent killer may also be unclean water! Poor water quality can encourage the formation of algae that looks terrible and endangers your little friends.

Possible Solution

  • Keep your aquarium’s pH around 6.5 to 7.8, which is the perfect range for aquatic plant growth.
  • The Pothos life will appreciate it if you keep the water fresh and clean in your aquarium once a month.


Your aquatic plants need fertilization just like any other plant does. The amount of nutrients in tap water is insufficient for optimal growth.

Overfeeding aquatic plants is just as detrimental as underfeeding them. Maintaining your plant properly is the technique to go for a superb marine habitat in the convenience of your home.

Possible Solution

  • The finest fertilizer for your tank plants is one that contains iron. So use iron-based fertilizer.
  • Make sure you are using the recommended dosage.
  • Apply the fertilizer designed for aquariums.
  • You should not use conventional liquid fertilizers. Ensure to use the appropriate one so that your fish are not harmed.

Fish Meals

The Pothos in your aquarium absorb everything you add to it. The plant roots ingest the extra meal after your fish have finished eating. The plants also take up the waste that your fishes pass out.

Sometimes toxic chemicals like sulfur are generated during the decomposition of such food and waste components. Additionally, the plants start to degrade due to absorbing these substances. The roots begin to rot.

The tank’s water quality is impacted by root degradation. Your fish will begin to exhibit bloating conditions in just a few times, and some of them could even lose their ability to swim.

Possible Solution

  • Make sure to remove any remaining food debris.
  • It would be excellent to have fish and snails that maintain the tank by ingesting waste and algae, such as Corydoras and Plecostomus catfish. Your hornwort and Pothos will be grateful for it.

Hostile Tankmates

Some turtles and fish adore nibbling on leaves and roots. The others, though, could be a little more combative. They could love tugging the plants till they float helplessly while playing.

Not every fish enjoys the extra plant material. Silver Dollar, Monos, and Tetras tend to be more combative. They like munching on your plants. Your plants won’t live very long if you keep these tiny companions. Some bottom feeders like chowing down on the roots. They may cause a complete disaster.

Possible Solution

  • Avoiding aggressive plant eaters is the best course of action for saving your tank plants. Put Cory catfish, Goldfishes, Tetras, and Rasboras in their place.

Frequently Asked Questions (FAQs)

Aquarists love to add Pothos to their aquarium. But sometimes they wonder about some facts. Below are some more typical ones:

Can Pothos Plants Grow Fully Submerged in The Aquarium?

No, it will finally perish. Additionally, this will raise the nitrate levels in the water rather than lower them.

As a result, make sure the water contains just the roots. To maintain the leaves far from the tank, you can distribute the branches outside the tank’s opening.

How Long Can a Pothos Live Underwater?

Although Pothos may survive in water, they usually perish when immersed. Pothos leaves dislike being submerged in water. The leaves quickly become mushy and rotting when they come in contact with water. They may live for up to ten years under ideal growth circumstances.
