PlantFun
Plant Needs
Sunlight
Bright full sun to partial sun; consistent light supports trap function and flowering
Watering
Submerged in still or slow-moving freshwater; maintain clean, nutrient-poor water to avoid algal overgrowth
Temperature
Thrives in warm tropical to subtropical temperatures; avoid prolonged exposure below 12°C
Characteristics
- Leaf: Submerged linear leaves (2–5 cm long) arranged in whorls along stems
- Flower: Pale lavender to white snapdragon-like blooms on emergent 15–30 cm stalks
- Traps: Tiny bladder-shaped structures on leaf surfaces to capture microfauna
Care Guide
Watering
Maintain consistent water level; top up with dechlorinated water as needed
Fertilization
No supplemental fertilization required; prey provides necessary nutrients. Avoid nutrient-rich fertilizers which can outcompete the plant and reduce trap efficiency
Diluted established aquarium water：Use only water from low-nutrient, well-cycled aquariums; dilute 1:10 to avoid introducing excess nutrients that harm trap functionPruning
- Trim yellowing submerged stems to maintain water clarity and reduce organic buildup
- Remove spent flower stalks after blooming to redirect energy to trap growth
- Thin overcrowded stems every 2–3 months to improve light penetration for lower foliage
Toxicity
Warning: this plant may be toxic.
Pets & Humans
Pets: ASPCA: Non-toxic to cats
