In an Iwagumi aquascape, the choice of carpet plants is crucial to achieve the minimalistic beauty and balance. Each plant offers unique textures and growth patterns that contribute to the overall serenity of the layout.

In this article, I’ll talk about 7 carpeting plants that work wonderfully in an iwagumi aquascape. Whether you are a beginner or want to create an advanced iwagumi aquascape, you can choose a number of plants mentioned in this article.

Top 7 Carpet Plants for Iwagumi Aquascapes

Eleocharis parvula (Dwarf Hairgrass)

1. Eleocharis parvula (Dwarf Hairgrass)

Dwarf Hairgrass creates a lush, grass-like carpet, mimicking a miniature field. Its relatively easy care makes it a favorite for aquarists aiming to achieve a naturalistic Iwagumi.

Hemianthus callitrichoides also known as HC cuba

2. Hemianthus callitrichoides ‘Cuba’ (HC)

Hemianthus callitrichoides ‘Cuba’, or HC, is coveted for its small leaf size and dense growth. This carpet plant requires more light and CO2 but rewards with a stunning, vibrant green carpet.

Utricularia graminifolia is a unique carnivorous plant that forms a soft, velvety carpet. It may require more patience to establish but offers an exceptional aesthetic once settled.

Marsilea hirsuta

6. Marsilea hirsuta

Marsilea hirsuta presents a different look with its clover-like appearance. It adapts well to various conditions and grows relatively slowly, providing an elegant and textured green spread.

Eleocharis acicularis 'mini'

7. Eleocharis acicularis ‘mini’

The ‘mini’ version of Eleocharis acicularis is perfect for smaller tanks due to its short growth. It’s an excellent choice for aquarists seeking the appearance of Dwarf Hairgrass in a more compact form.

Criteria for Selecting Carpet Plants

When I set out to create an Iwagumi aquascape, selecting the right carpet plants is crucial. These plants form the lush greenery that closely emulates the serenity of a natural landscape, laying the foundation of this minimalist style.

Growth Patterns:

I look for plants that spread horizontally, forming a dense, low-growing carpet. The plants should ideally have the ability to grow over rocks, as seen in typical Iwagumi layouts.

  • Lighting Considerations: The species I choose must thrive under the lighting conditions specific to my tank. Iwagumi aquascapes often require high lighting to promote compact, healthy growth.
  • CO2 Requirements: These plants frequently necessitate a consistent CO2 supply, which aids in preventing algae and ensures vibrant coloration.
  • Substrate Needs: A nutrient-rich substrate is fundamental. The substrate should support root growth while also complementing the overall minimalist appearance.


I’m mindful of the maintenance and care each plant demands. For example, some may need frequent trimming to maintain their shape.

Care Requirements:

  • Regular trimming prevents overgrowth.
  • Adjustments to CO2 and nutrients help manage plant health and appearance.

By keeping these criteria in mind, I can ensure my Iwagumi aquascape’s carpet plants are not only functional but also contribute to the aesthetic tranquility of the layout.

How To Plant Carpeting Plants For Good Coverage?

When planting carpeting plants in an Iwagumi aquascape, I ensure that each step promotes uniform growth and coverage. Here’s how I achieve that:

1. Prepare the Substrate: I start with a nutrient-rich substrate, laying it out in a gentle slope for depth perception. This aids in the visibility and growth of carpet plants.

2. Section the Plants: Typically, carpeting plants come in pots or mats. I divide them into smaller clumps to maximize spread and coverage.

3. Plant Evenly: Using tweezers, I plant the clumps evenly across the substrate. Distance between each clump should be approximately an inch, giving room for expansion.

4. Adequate Lighting: Good lighting is crucial. I maintain high-quality lights to encourage compact growth.

5. CO2 and Fertilization: I introduce CO₂ supplementation and liquid fertilizers to support plant health and expedite carpet formation.

By following these tips, I’ve successfully cultivated dense and healthy carpets for my Iwagumi aquascapes.

Maintenance Of Carpeting Plants

In maintaining carpeting plants for an Iwagumi aquascape, it’s vital to ensure optimal water parameters and plant nutrition. I’ll take you through the essentials of water quality and lighting needs that are pivotal for the health and growth of your carpet plants.

Water Parameters and Quality

The health of carpeting plants in an Iwagumi aquascape greatly depends on maintaining proper water parameters. I meticulously test the water for pH levels, which should ideally be between 6.5 and 7.5, and I make sure the water hardness (GH and KH) is appropriate for the plants’ needs.

To sustain superior water quality, frequent water changes are a must—typically, I recommend changing 25-50% of the tank’s water weekly, depending on the tank size and bioload from fish or shrimp.

Ammonia and nitrate levels must be kept at bay to prevent algae growth, which competes with carpet plants for nutrients.

Lighting, CO2, and Fertilization

Lighting is crucial for carpeting plants’ photosynthesis, so I employ lights that provide full-spectrum coverage. For most carpet species, around 8-10 hours of light per day is adequate.

Carpeting plants thrive with supplemental carbon dioxide (CO2), so I use a CO2 system to maintain levels at about 25-30 ppm, which accelerates plant growth and helps them outcompete algae. I also recommend using a nutrient-rich substrate to promote strong root systems.

Fertilization is equally important; a combination of root tabs and liquid fertilizers ensures that plants receive all the necessary nutrients.

I dose micronutrients and macronutrients according to the plants’ needs and growth rates, following the instructions from the aquarium store depot where I purchase my supplies.

Which plant species are considered ideal for creating a carpet in low-tech Iwagumi aquariums?

For those who are new to aquascaping, I recommend starting with plant species that are low-maintenance and thrive in low-tech tank conditions. Options such as Java Moss and Marsilea hirsuta are excellent for creating lush carpets without the need for extensive lighting or CO2 systems.

How do Glossostigma elatinoides and Lilaeopsis brasiliensis compare as carpet plants for Iwagumi layouts?

Glossostigma elatinoides is known for its rapid growth and demands more light and CO2, making it a bit of a challenge for beginners. Lilaeopsis brasiliensis, on the other hand, is easier to manage and can form tight green carpets even under moderate lighting.

Can Dwarf Hairgrass be effectively used in a Nano Iwagumi setup, and what are its care requirements?

Dwarf Hairgrass is indeed a popular choice for Nano Iwagumi setups due to its fine texture and the ease with which it forms dense carpets. It flourishes with moderate to high lighting and benefits from CO2 supplementation, but it can still grow well in a nano aquarium with careful attention to lighting.

What are the top plant choices to complement the minimalist style of a Japanese Iwagumi aquascape?

To maintain the minimalist aesthetic of an Iwagumi aquascape, selecting the right plants is crucial. Eleocharis acicularis (Dwarf Hairgrass) and Hemianthus callitrichoides (‘Cuba’) are favorites for their understated appearance and the clean lines they afford an aquascape.

When choosing background plants for an Iwagumi aquascape, I look for species that offer vertical growth and simple foliage. Tall, slender plants such as Vallisneria and various stem plants like Rotala rotundifolia can elegantly frame an Iwagumi layout without overwhelming its minimalist nature.
