Care Guide
Watering
Maintain consistent water level; top up with dechlorinated water as needed
Fertilization
Diluted carnivorous plant fertilizer every 4 weeks. Do not use standard houseplant fertilizer, as high nutrients will harm the plant
Established aquarium water runoff：Use only water from low-nutrient, algae-free aquariums; dilute 1:1 with dechlorinated water before adding to the setupPruning
- Remove decaying plant material regularly to prevent water fouling and algae growth
- Thin overcrowded mats to improve light penetration and trap efficiency
- Trim spent flower stalks to redirect energy to new trap and stem growth
