Lagarosiphon schweinfurthii

Lagarosiphon schweinfurthii is native to East Africa, particularly around Lake Victoria and the East African Rift lake system, where it grows in alkaline, hard, oxygen-rich water. It produces elongated stems bearing small, finely recurved leaves denser than the common L. major, and it is uniquely well-adapted to the high pH and carbonate hardness of rift lake aquariums where many other oxygenating plants struggle. It grows vigorously without CO2 under moderate light and provides excellent shelter and oxygenation in cichlid tanks housing East African species. It is more tolerant of warm water than L. major, making it usable in fully tropical setups as well.
