Why Pothos Are One of the Best Plants for Aquariums

If you’re looking for a low-maintenance, beautiful, and functional plant for your aquarium, pothos (Epipremnum aureum) should be at the top of your list. These hardy houseplants can thrive with just their roots submerged in water, making them an excellent choice for both beginner and experienced aquarists. Not only do they add a lush, jungle-like aesthetic to your tank, but they also grow quickly with minimal care.

One of the biggest advantages of keeping pothos in your aquarium is their ability to absorb nitrates—a byproduct of fish waste that can become toxic at high levels. By pulling nitrates and other excess nutrients directly from the water, pothos act as a natural filtration system. This helps improve water quality, reduce stress on your fish, and even minimize the need for frequent water changes.

In addition to improving water parameters, pothos can also help control algae growth. Since they outcompete algae for nutrients, they can naturally reduce unwanted algae blooms in your tank. Plus, their long, trailing roots provide shelter and security for fish, especially shy species or fry. With no need for CO2 injection or special lighting, pothos are a simple and effective way to boost the health and beauty of your aquarium.
