Floating Crystalwort: Riccia fluitans

Floating Crystalwort

Floating Crystalwort, scientifically known as Riccia fluitans, is a delicate and visually captivating aquatic plant recognized for its unique floating morphology and vibrant green coloration. This plant possesses small, flat, and translucent structures that form a lush carpet-like appearance on the water's surface. In aquascaping, Riccia fluitans serves both aesthetic and functional roles, enhancing the visual depth of an aquarium while also providing shelter and breeding grounds for various aquatic organisms.

Care Guide

To maintain the health and vibrancy of Floating Crystalwort, consider the following care instructions:

• Light Requirements: Riccia fluitans thrives in moderate to high lighting conditions. It requires at least 8-10 hours of light per day to maintain its lush appearance and to facilitate optimal growth. LED or fluorescent lights are recommended to supply adequate illumination while minimizing heat.

• Water Parameters: This plant prefers a pH range of 6.0 to 7.5 and can tolerate temperatures between 20°C to 28°C (68°F to 82°F). Regular water changes and a stable environment are crucial for its health.

• Flow: Moderate water flow is ideal, as it helps prevent debris buildup and ensures proper distribution of nutrients.

• Pruning and Harvesting: Riccia fluitans should be pruned periodically to prevent overgrowth and maintain its desired shape. Remove any discolored or decaying portions to promote healthy growth.

Nutrient Requirements

For optimal growth and development of Floating Crystalwort, attention to nutrient levels is essential:

• Light: As previously mentioned, high-quality lighting is crucial. Ensure your lighting fixtures provide the right spectrum and intensity for aquatic plants.

• CO2: While Riccia fluitans can thrive in low CO2 environments, injecting CO2 can significantly boost its growth rate, particularly in more densely planted aquariums.

• Fertilization: Utilize a balanced liquid fertilizer or root tabs designed for aquatic plants to supply essential nutrients like nitrogen, phosphorus, potassium, and micronutrients. Regular fertilization will enhance the plant's growth and lushness.

Natural Biomes

Riccia fluitans is commonly found in various natural biomes, including:

• The Amazon Basin – where it thrives in slow-moving waters rich in organic matter.
• The Orinoco – characterized by its nutrient-dense waters and diverse aquatic habitats.
• The Mekong Delta – presenting an ideal environment with its braided river systems and abundant plant life.

Livestock Compatibility

Floating Crystalwort provides an excellent habitat for a variety of fish and shrimp species. Ideal tank mates include:

• Neocaridina Shrimp: Such as Cherry or Crystal Red shrimp, which benefit from the shelter and grazing opportunities provided by Riccia fluitans.
• Small Tetras: Species like Neon Tetras and Rummy Nose Tetras enjoy swimming among the floating fronds while foraging for small food particles.
• Peaceful Gouramis: Dwarf Gouramis and other small, peaceful species appreciate the shaded areas that Riccia fluitans creates.

Incorporating Floating Crystalwort into your aquascape not only enhances its visual appeal but also fosters a vibrant ecosystem for various aquatic inhabitants.
