How do you Prepare Pothos for your Aquarium?

Getting your Pothos ready for its new aquatic home is a vital initial step. Here’s a more in-depth look at how to prepare your Pothos:

  1. Choose a Healthy Pothos: Start by selecting a Pothos plant that’s in excellent condition. Look for vibrant green leaves and sturdy stems. Ensure it’s free from pests or diseases that could potentially harm your fish.
  2. Trim the Roots: Carefully trim any excess or damaged roots from your Pothos. This not only encourages new growth but also prevents root rot in your aquarium.
  3. Give it a Good Rinse: Before introducing Pothos to your aquarium, gently rinse the plant under running water to remove any dirt or debris. This will help keep your aquarium water clean and clear.
  4. Gradual Submersion: Instead of immediately placing Pothos into your aquarium, start by submerging it in a separate container filled with dechlorinated water. This helps acclimate the plant to its new aquatic environment.

How do you Attach Pothos to the Aquarium?

Now that your Pothos is prepped and ready, it’s time to attach it to your aquarium. Here’s a step-by-step guide for different placement options:

  1. Choose the Right Spot: Decide where you’d like to place your Pothos within the aquarium. You have a few options: you can let it float on the water’s surface, partially submerge it, or fully submerge it. Each placement has its unique benefits.
  2. Using a Weight: If you prefer the submerged look, you can attach a small weight (like a plant weight or a fishing sinker) to the base of your Pothos. This helps keep it submerged until it develops its aquatic roots.
  3. Hanging Pothos: For a cascading effect into your aquarium, hang the Pothos over the top edge of the tank. You can use a suction cup with a clip or any aquarium-safe clip to hold it in place.
  4. Planting in Substrate: If you want your Pothos to grow its roots directly into the substrate, plant it in a small pot with aquarium substrate and then place the pot in your aquarium. This method allows for nutrient absorption from the substrate.
  5. Monitor Placement: Keep a close eye on the placement of your Pothos in its new location. Ensure it’s secure and not causing any disturbances to your fish or tank equipment.

How to Take Care of Pothos in Aquarium?

Congratulations, your Pothos is now a part of your aquatic world! To ensure it thrives and continues to benefit your aquarium, let’s delve deeper into how to take care of it:

1. Provide Indirect Light

Pothos is a low-light plant and thrives in indirect light. Avoid placing it in direct sunlight, as this can cause the leaves to scorch. Instead, consider using aquarium LED lighting or placing it near a window with filtered sunlight.

2. Regular Water Changes

Regular water changes are crucial to maintaining water quality in your aquarium. Since Pothos absorbs nitrates and other pollutants from the water, it’s essential to replace the water periodically to replenish essential nutrients for your fish.

3. Maintain Warm Temperatures

Pothos prefers warmer water temperatures, typically in the range of 70-90°F (21-32°C). Ensure your aquarium’s water temperature stays within this range to keep your Pothos thriving.

4. Prune the Roots

To prevent overcrowding and maintain healthy root growth, trim the Pothos roots as needed. Regular pruning also helps with water circulation and prevents the roots from clogging filters.

5. Nutrient Supplement

While Pothos absorbs nitrates and other nutrients from the water, you can occasionally provide a diluted aquarium fertilizer to ensure it receives essential nutrients for optimal growth.

Will Pothos Kill Other Aquarium Plants?

A common concern among aquarium enthusiasts is whether adding Pothos will harm other aquatic plants. The good news is that Pothos is generally considered a cooperative and non-invasive plant that coexists well with other aquatic flora. It doesn’t compete for nutrients in the substrate, primarily absorbing nutrients from the water column. Therefore, it’s unlikely to harm other plants in your aquarium.

In fact, Pothos can be a beneficial addition as it helps reduce nitrates in the water, which can benefit the overall health of your aquatic plants.

Benefits of Using Pothos in Aquarium

Adding Pothos to your aquarium offers a plethora of benefits:

  • Improved Water Quality: Pothos actively absorbs nitrates, ammonia, and other pollutants from the water, leading to significantly enhanced water quality.
  • Natural Filtration: It acts as a natural filter, reducing the need for frequent water changes and contributing to the overall health of your aquarium ecosystem.
  • Oxygen Production: During photosynthesis, Pothos releases oxygen, benefiting your fish and other aquatic inhabitants.
  • Aesthetic Enhancement: Pothos adds a vibrant touch of greenery to your aquarium, elevating its visual appeal.

Common Problems of Pothos in Aquariums

While Pothos can be a fantastic addition to your aquarium, there are some common issues to be aware of:

Extensive Pothos roots can potentially clog filters if left unattended. Regular pruning of the roots can help prevent this issue and maintain proper water flow.

2. Fish Food

While Pothos helps with water quality, it doesn’t replace the need for proper fish food. Ensure that your fish are still receiving adequate nutrition.

Can Aquarium Glue Be Used to Attach Pothos to Decorations in an Aquarium?

Yes, using aquarium glue effectively can be a great way to attach pothos to decorations in an aquarium. This adhesive is specially designed to be safe for underwater use, ensuring the health and well-being of aquatic life.

Can I Put My Pothos Plant in the Aquarium with My Lucky Bamboo Plant?

Adding lucky bamboo to your aquarium may seem like a unique option, but caution is advised when considering compatibility with other plants like the pothos plant. While lucky bamboo can thrive rooted in water, it may disrupt the ecosystem and hinder the growth of other aquatic flora. It’s best to research each plant’s requirements before attempting such an arrangement.

Can I Vacuum the Gravel in my Aquarium If I Have Pothos Plants?

When it comes to maintaining your aquarium, many fishkeepers wonder if vacuuming gravel in aquarium could harm the pothos plants. While it’s crucial to keep the gravel clean to ensure a healthy environment, caution is necessary. Gently vacuum around the plants, avoiding direct contact, to prevent damaging the delicate roots.

Can Pothos Plants Introduce Detritus Worms into an Aquarium?

Pothos plants are a popular choice for aquariums due to their ability to absorb excess nutrients, aiding in algae control. However, it is important to note that these plants can introduce detritus worms into the aquarium. Detritus worms in aquariums can thrive on decaying matter, potentially leading to poor water quality and health issues for aquatic inhabitants. Regular monitoring and maintenance are crucial to prevent any undesirable outcomes.

Can I Use the Same Method to Plant Pothos in Pots in an Aquarium?

Yes, it is possible to plant aquarium plants in pots, but using the same method for pothos may not be ideal. Pothos is a terrestrial plant that can tolerate underwater conditions for short periods. However, it doesn’t thrive fully submerged. To properly grow pothos in an aquarium, consider utilizing a floating plant basket or letting it trail out from the top of the tank.

Can I Propagate Pothos in my Aquarium?

Propagating aquarium plants effectively is key when considering whether pothos can be propagated in your aquarium. Pothos, a popular houseplant, can indeed thrive in aquariums by solely submerging its roots. With proper care and monitoring, you can successfully propagate pothos in your aquarium, providing a lush and green aesthetic to your underwater world.

3. Unfriendly Tankmates

Some fish species may nibble on Pothos leaves. Be mindful of your tank’s inhabitants and monitor their behavior. If you notice excessive nibbling, consider providing alternative hiding spots or plant cover.

Is Pothos Safe for Aquariums?

Pothos is generally safe for aquariums, provided you follow the care guidelines and keep an eye on its growth. It can be a valuable addition to your aquatic environment, contributing to better water quality and enhancing the visual appeal of your tank.

However, always be vigilant about its growth to prevent potential issues with clogged filters or overenthusiastic fish.


Incorporating Pothos into your aquarium is a rewarding and beneficial endeavor. This versatile plant not only adds a touch of nature’s beauty to your underwater world but also actively contributes to improved water quality and the well-being of your fish. By following the care guidelines and addressing any potential issues promptly, you can enjoy a harmonious and thriving aquarium ecosystem.
