Care Notes
‘Assam’ adapts to a wide range of aquarium conditions and can grow with anything from low to high lighting. CO₂ supplementation is beneficial but not strictly necessary, while consistent macro- and micronutrient availability will encourage healthy, compact growth.
Propagation is simple: trim healthy stems and replant the cuttings into the substrate. Regular trimming encourages branching and helps create a fuller, bushier appearance.
