Dwarf Sagittaria Subulata, also known as Dwarf Sag, is an incredibly popular and easy-to-care-for aquarium plant that’s perfect for beginners. It resembles a lush, vibrant green carpet of grass, making it a fantastic choice for foregrounds in aquascapes.

Here’s a breakdown of its key features and care requirements:

Scientific Name: Sagittaria subulata

Common Names: Dwarf Sagittaria, Dwarf Sag, Narrow Leaf Sagittaria

Appearance: This plant has narrow, grass-like leaves that are typically bright green. It usually stays relatively short, reaching a height of 2-6 inches (5-15 cm) in aquariums, but can grow taller in lower light conditions.

Care:

• Lighting: Adaptable to a wide range of lighting conditions, from low to high. Brighter light encourages a more compact growth habit.
• Water Parameters: Thrives in a pH range of 6.5 to 7.5 and a temperature between 68-82F (20-28C).
• Substrate: A nutrient-rich substrate is beneficial. While it can grow in gravel, a finer substrate like sand allows for better root development.
• CO2: CO2 injection is not required but can enhance growth and promote a denser carpet.
• Propagation: Propagates easily through runners. It sends out horizontal stems that develop new plantlets, quickly forming a dense carpet.

Placement: Primarily used as a foreground plant due to its short stature. It can also be used in the mid-ground in smaller aquariums.
