Hydrocotyle tripartite

Hydrocotyle sp. 'Japan' is the common name for this plant in various plant forums. It is a variant of the tripartite Hydrocotyle from Southeast Asia. It is characterized by rapid, compact growth and small, deep green leaves on upright stems.
The plant forms a carpet (5-10 cm high) and its compact growth can be promoted by physically pressing the carpet with your hand during aquarium maintenance (mechanical retardation). Carpet formation and compact growth work best with good light.
