Planting Vallisneria in your aquarium requires some care and attention to ensure its successful growth. Follow these steps to establish a thriving Vallisneria population:

  1. Substrate Placement: Vallisneria roots itself in the substrate, so choose a fine-grain substrate like aquarium sand to provide a stable base for the plants. Make sure the substrate is deep enough for the plant to anchor securely.
  2. Spacing: Depending on the species, Vallisneria should be planted with appropriate spacing. For Vallisneria Spiralis, plant them around 3 to 5 inches apart, while Jungle Vallisneria should have a spacing of 6 to 8 inches.
  3. Lighting: Provide moderate to high lighting for optimal growth. Vallisneria thrives in well-lit environments, and proper lighting encourages lush, healthy leaves.
  4. Fertilization: Although Vallisneria can absorb nutrients from the water column, supplementing with root tabs or liquid fertilizers can promote faster growth and more vibrant leaves.
  5. Water Conditions: Vallisneria adapts well to a range of water parameters. However, maintaining a temperature between 72-82°F (22-28°C) and a pH level of 6.5-8.0 is ideal.

Benefits of Vallisneria in Your Aquarium

Vallisneria offers several benefits to your aquarium ecosystem, making it a valuable addition:

  1. Oxygenation: Through photosynthesis, Vallisneria releases oxygen into the water, ensuring a healthy oxygen level for your fish and other aquatic inhabitants.
  2. Natural Filtration: The plants’ root systems help remove excess nutrients and toxins from the water, promoting water clarity and reducing the likelihood of algae blooms.
  3. Habitat Enhancement: Vallisneria provides an excellent habitat for fish to seek shelter, lay eggs, and explore. The dense underwater vegetation creates a more natural environment for your aquatic pets.
  4. Algae Competition: By consuming nutrients in the water, Vallisneria limits the availability of resources that algae need to grow. This natural competition helps control algae growth in your tank.

Does Vallisneria need CO2? 

Vallisneria is a versatile aquatic plant that can thrive without supplemental CO2 injection in many aquarium setups. It can absorb carbon dioxide from the surrounding water, especially if the aquarium is well-maintained with proper lighting and water circulation. However, in high-tech planted tanks or setups with intense lighting and demanding plant growth, adding CO2 can enhance Vallisneria’s growth rate and overall health.

What is Vallisneria used for? 

Vallisneria serves several essential purposes in the aquarium:

  1. Aesthetic Enhancement: Vallisneria adds natural beauty to your aquarium with its long, flowing leaves. It creates a lush underwater landscape that enhances the visual appeal of the tank.
  2. Oxygenation: Through photosynthesis, Vallisneria releases oxygen into the water, benefiting the aquatic inhabitants, particularly fish, and other oxygen-dependent organisms.
  3. Water Filtration: The plant’s roots help filter the water by absorbing excess nutrients, thereby reducing the risk of algae overgrowth. Vallisneria contributes to maintaining water clarity.
  4. Fish Shelter: Vallisneria provides shelter for fish, especially smaller species or fry, creating safe spaces for them to hide and explore.
  5. Algae Control: By competing for nutrients, Vallisneria helps control the growth of algae in the aquarium, creating a healthier and more balanced ecosystem.

Can Vallisneria grow out of water? 

Yes, some Vallisneria species, like Vallisneria americana, can grow partially emerged or even entirely out of water. When grown emersed, the plant may produce different leaf forms that are adapted to the aerial environment. This growth pattern can be seen in the wild, where Vallisneria often grows along the edges of bodies of water or in marshy areas.

What are some interesting facts about Vallisneria?

  • Vallisneria gets its common name, “eelgrass,” due to the long, ribbon-like shape of its leaves.
  • It’s a dioecious plant, which means that individual plants are either male or female. Female plants produce flowers that rise to the water’s surface, while male flowers remain submerged.
  • Vallisneria is an excellent choice for beginner aquarists due to its hardiness and adaptability to a range of water conditions.
  • The plant can undergo a “melting” phase when introduced to a new tank. This is a temporary adjustment period during which some older leaves may deteriorate while new growth appears.
  • In the wild, Vallisneria plays a crucial role in stabilizing sediments, preventing erosion along shorelines, and providing habitat for aquatic organisms.


Vallisneria Aquarium Plants bring a touch of natural elegance to your fish tank. From their graceful leaves to the benefits they offer for your aquarium ecosystem, Vallisneria is a valuable addition for any aquarist. Whether you’re an experienced hobbyist or just starting your aquatic journey, the beauty and functionality of Vallisneria make it a captivating choice.
