Place of Origin: Southeast Asia

Rotala sp. 'Bossii' is a visually striking aquatic plant that has gained popularity among aquarists for its elegant appearance and manageable care requirements. Native to Southeast Asia, this stem plant is known for its slender, upright growth and attractive coloration, making it a fantastic addition to any aquascape.

Appearance

Rotala Bossii features narrow, elongated leaves that can range from a vibrant green to shades of reddish-brown, depending on the lighting and conditions in which it is grown. The leaves grow in pairs along the stem, creating a lush and dense appearance that can reach heights of 30-50 cm. When exposed to high lighting, the tips of the leaves can develop a beautiful reddish hue, enhancing its visual appeal in the aquarium.

Aquarium Care and Requirements

Lighting:
This plant thrives under moderate to high lighting conditions. Adequate light is essential for maintaining its vibrant coloration and promoting healthy growth. Insufficient lighting may lead to elongated stems and a loss of the attractive reddish tones.

Substrate and Nutrients:
Rotala Bossii benefits from a nutrient-rich substrate that supports robust root development. Regular use of root tabs and liquid fertilizers containing iron and other essential micronutrients will help ensure the plant receives the nutrients it needs for optimal growth.

Water Parameters:

• Temperature: 72-82°F (22-28°C)
• pH: 6.0-7.5
• Hardness: Soft to moderately hard water (2-12 dGH)

CO2 Injection:
While Rotala Bossii can grow without additional CO2, incorporating CO2 injection into your aquarium setup will significantly enhance its growth rate and coloration. In high-light setups, CO2 is particularly beneficial, allowing the plant to flourish and develop its stunning colors.

Pruning and Propagation:
Regular pruning is important to maintain a bushy appearance and prevent legginess. Trim back the tops of the stems to encourage new side shoots and denser growth. Propagation is easy; simply cut the stem below a leaf node and replant the cutting in the substrate, where it will root and grow into a new plant.

Benefits to the Aquarium

Rotala Bossii is not only an aesthetically pleasing addition to your aquarium but also serves a practical purpose. Its dense foliage provides shelter for small fish, shrimp, and fry, offering them a safe haven in the tank. Additionally, the plant contributes to water quality by absorbing excess nutrients, helping to control algae growth.
