The Best Plants for a Guppy Tank


Guppies, those colorful and lively fish, are a favorite among aquarium enthusiasts. To create an ideal habitat for your guppies, it’s essential to incorporate live plants into their tank. Live plants not only enhance the aesthetics of the tank but also serve practical purposes like providing shelter, oxygen, and helping with water quality. In this article, we’ll explore the best plants for a guppy tank, prioritizing expert advice and lesser-known options to help you create a thriving aquatic ecosystem for your beloved guppies.

The Importance of Live Plants

Before diving into the specific plant choices, let’s highlight why live plants are crucial for a guppy tank:

1. Aesthetic Appeal

Live plants add a natural and vibrant touch to your aquarium, mimicking the guppies’ natural habitat. This makes for a visually pleasing setup that can be enjoyed by both beginners and seasoned aquarists.

2. Oxygen Production

Plants perform photosynthesis, releasing oxygen into the water during the day. Guppies, like all fish, require oxygen to breathe, making live plants an invaluable source of this vital gas.

3. Filtration and Water Quality

Plants help maintain a stable and healthy aquatic environment by absorbing nitrates, ammonia, and other waste products excreted by your fish. This natural filtration system contributes to cleaner water and less maintenance.

4. Providing Shelter

Guppies need hiding spots to feel safe. Live plants offer them ample hiding places, reducing stress and aggression within the tank.

5. Algae Control

Some plants can outcompete algae for nutrients, helping to control unwanted algae growth in your tank.

Choosing the Right Plants

Now, let’s explore the top live plant options for a guppy tank, taking into account the uncommon and expert recommendations:

1. Anubias Barteri (Anubias Nana)

Anubias Barteri, often referred to as Anubias Nana, is a hardy and attractive plant that thrives in guppy tanks. It’s known for its low light requirements, making it suitable for beginners. Anubias can be attached to driftwood or rocks, creating natural ornaments within the tank. Guppies appreciate the broad leaves of this plant for hiding and resting.

2. Java Moss (Taxiphyllum Barbieri)

Java Moss is an excellent choice for guppy tanks due to its ease of care and ability to create dense, green carpets. Guppies often use Java Moss as a breeding ground, and it also serves as an effective algae inhibitor. Attach it to decorations or let it float freely in the tank for a more natural look.

3. Hornwort (Ceratophyllum demersum)

Hornwort is an expert’s choice for guppy tanks. This fast-growing plant provides superb shelter and helps maintain water quality. Its fine, feathery leaves offer guppies an excellent environment for breeding, and it’s a top oxygen producer. Guppies will find the thickets of Hornwort ideal for hiding and exploring.

4. Amazon Sword (Echinodorus grisebachii)

Amazon Swords are striking plants that can grow quite large. They make for an eye-catching centerpiece in your guppy tank and provide ample hiding places for your fish. These plants are also nutrient hogs, which can help keep water parameters stable.

5. Water Wisteria (Hygrophila difformis)

Water Wisteria is an underrated plant that’s both beautiful and functional. Its delicate, lacy leaves create a gentle and calming effect in the tank. Guppies appreciate the soft texture and use it for hiding and resting. Water Wisteria is also proficient at nutrient absorption, helping to keep your tank water clear.

6. Duckweed (Lemna Minor)

Duckweed, though often considered a pest, can be advantageous in guppy tanks. It forms a floating mat that provides shade, which can be appreciated by guppies in well-lit tanks. It’s a quick grower, making it an effective nutrient sponge and contributing to water quality.

7. Dwarf Baby Tears (Hemianthus callitrichoides)

For those looking to create a lush, carpeted look in their guppy tank, Dwarf Baby Tears are a challenging but rewarding choice. These small plants require high light and CO2 supplementation, making them suitable for more advanced aquarists. Guppies may use the dense carpet as a breeding ground and shelter.

8. Cryptocoryne (Cryptocoryne spp.)

Cryptocoryne plants come in various species, and they are known for their distinctive, broad leaves. Guppies find them perfect for resting and hiding. Crypts are low-maintenance and are known for adapting to various water conditions, making them suitable for beginners and experts alike.

Plant Care Tips

To ensure your selected plants thrive in your guppy tank, follow these expert care tips:

Lighting: Choose appropriate lighting based on your plant selection. Low-light plants like Anubias require less, while high-light plants like Dwarf Baby Tears need intense lighting.

Fertilization: Consider using a balanced aquarium fertilizer to provide essential nutrients to your plants.

Substrate: Use a suitable substrate for rooted plants like Amazon Swords and Cryptocoryne. Fine gravel or sand works well.

Pruning: Regularly trim and maintain your plants to prevent overgrowth and ensure the guppies have enough swimming space.

CO2: Advanced aquarists may opt for CO2 supplementation to promote plant growth, particularly for demanding plants like Dwarf Baby Tears.


Incorporating live plants into your guppy tank can significantly enhance the well-being of your fish and the overall aesthetics of the aquarium. From easy-to-maintain options like Anubias and Java Moss to more challenging choices like Dwarf Baby Tears, there’s a plant to suit every aquarist’s skill level and preference. By following expert care tips and choosing the right plants, you can create a lush and vibrant underwater paradise for your guppies.
