The Benefits of Dwarf Hairgrass in Your Aquarium: A Versatile and Beautiful Aquatic Plant

Introduction to Dwarf Hairgrass

Aquascaping has become increasingly popular among aquarium enthusiasts. Adding live plants to your tank not only enhances its aesthetic appeal, but it also provides many benefits for the aquatic ecosystem.

One of the most popular and easiest to care for aquatic plants is the Dwarf Hairgrass (Eleocharis acicularis or Eleocharis parvula). Dwarf Hairgrass is a relatively new addition to the aquarium hobbyist community, and it was first introduced in the aquatic trade in the early 2000s.

It belongs to the Cyperaceae family and is native to North America, Europe, and Asia. Dwarf Hairgrass is also known as Needle Spikerush, Slender Spike Rush, or Hair Grass.

Benefits of Adding Dwarf Hairgrass to Your Tank

Dwarf Hairgrass is a popular choice because of its appearance and versatility. Besides making your aquarium look more aesthetically pleasing, it also has many benefits for the tank.

Firstly, it oxygenates the water, creating a healthier living environment for all the aquatic creatures in the water. It also helps to remove toxins, such as ammonia and nitrates, from the aquarium, thereby reducing the risk of fish and other aquatic creatures getting sick.

Another benefit of adding Dwarf Hairgrass to your tank is its ability to control algae growth. Algae growth is one of the most annoying problems for aquarium owners, and Dwarf Hairgrass helps to keep it under control by actively competing with it for nutrients.

Additionally, it provides a natural habitat for microscopic organisms, which are essential for the proper functioning of the ecosystem in your aquarium.

Caring for Dwarf Hairgrass in the Aquarium

Tank size and water parameters for Dwarf Hairgrass

Dwarf Hairgrass is a relatively small plant that only grows to a maximum of 10 cm (4 inches) tall. Therefore, the tank size needed for Dwarf Hairgrass is dependent on the number of plants you want to have in your aquarium.

However, it is recommended to have at least a 5-gallon tank containing the plant. The water parameters of your tank are also crucial to the survival of Dwarf Hairgrass.

The ideal temperature for growing Dwarf Hairgrass is between 68-82F (20-28C), and the pH level should range between 6.5-7.5. The water hardness should be between 3-8dKH. Lighting conditions and substrate/fertilizers for Dwarf Hairgrass

Like most aquatic plants, Dwarf Hairgrass requires proper lighting conditions for photosynthesis, which is essential for its growth.

When setting up the lighting for Dwarf Hairgrass, choose bulbs that emit a full spectrum of light, and ensure that the light is consistent throughout the day. The recommended lighting for Dwarf Hairgrass is about 8-10 hours per day, depending on how deep the tank is and how much light it receives.

Another crucial factor in caring for Dwarf Hairgrass is the substrate that is used. The substrate should be nutrient-rich and provide enough oxygen for the plant to grow properly.

You can also add fertilizers or root tabs to the substrate to supplement the nutrients and ensure proper growth. Carbon dioxide is also essential for photosynthesis, and you can add it to your tank to help your plants thrive.

Planting and maintenance of Dwarf Hairgrass

The planting process of Dwarf Hairgrass is easy, and it involves the use of tweezers to plant the grass around the substrate carefully. Ensure that the roots of the plant are anchored well to the substrate by burying them about 1-2 inches deep.

Once you have planted the grass, add water slowly until it reaches the desired depth. Also, ensure that the water is not too deep such that it submerges the plant.

Maintenance of Dwarf Hairgrass is also easy and involves regular trimming to promote new growth. Trimming also helps to prevent the grass from spreading too much and taking over other plants in your aquarium.

It is also essential to check for algae growth and ensure that it does not spread too much and choke the plant. If algae begin to grow on the plant, you can use algae eaters or algae control products to stop the growth.

Propagation of Dwarf Hairgrass is through runners, and the plant is relatively easy to propagate. Runners are shoots or branches that grow out from the parent plant and can be used to create new plantlets.

You can either leave the runners to form new plants by themselves or cut them and plant them directly into the substrate.


In conclusion, Dwarf Hairgrass is an easy-to-care-for aquatic plant that comes with many benefits for the aquarium ecosystem. By following the recommended tank size, water parameters, lighting, substrate/fertilizer, and maintenance practices, you can grow this plant successfully in your aquarium.

Besides its benefits for the ecosystem, Dwarf Hairgrass is also a beautiful plant that enhances the aesthetic appeal of your aquarium. Get your Dwarf Hairgrass today and see the difference it makes to your aquarium!
