Care notes

This plant requires high light (at least 50 µmol/m²/s) to maintain a dense carpet. CO2 supplementation is highly recommended for optimal growth. Water parameters should be stable: temperature 20-26°C, pH 6-7.5, GH 2-10. A nutrient-rich substrate is beneficial. Regular trimming is needed to prevent lower parts from lacking light. It is compatible with most peaceful fish. Avoid burrowing fish that may uproot the plant.
