labelled as Eleocharis parvula
Known as Dwarf Hair Grass, this species doesn't get quite as tall as other in the genus. It creates nice tranquil fields of waving green grass when submersed and emersed it creates a unique textural contrast to most other stem and leaf plants.
Difficulty: Medium, expect to see a slow establishing period when grown both submersed and emersed. BUT once it takes hold it will take off! Best with CO2 and high light when grown submersed. Expect to see the original plants to get some brown tips before acclimating when grown emsered. They can be snipped off and new growth will be more hardy.
