Plant Needs
Sunlight
Bright indirect sunlight or partial shade; avoid intense midday sun that may overheat shallow water habitats
Watering
Requires constant standing freshwater; maintain clean, stagnant or slow-moving water to support growth
Temperature
Thrives in 15–22°C; tolerates brief drops to 10°C but cannot survive freezing conditions
Characteristics
- Frond (Leaf): Oblong to lance-shaped, with a distinct basal notch, floating on water surface
- Root: Single thin, thread-like root dangling below each frond
- Flower: Inconspicuous tiny green flowers, rarely produced outside natural habitats
Care Guide
Watering
Maintain consistent water level; top up with dechlorinated water as needed
Fertilization
Add diluted aquatic plant fertilizer once monthly. Use low-dose, aquatic-specific fertilizer to avoid water eutrophication
Freshwater aquarium runoff：Use water from weekly freshwater aquarium changes; add directly to water habitats to provide natural, low-concentration nutrients without chemical additivesPruning
- Thin overcrowded fronds to prevent oxygen depletion and maintain water clarity
- Remove yellowed or decaying fronds promptly to avoid water fouling
- Avoid disturbing root systems when thinning floating mats to prevent stress
