Propagation
This plant will propagate itself by sending out runners from the mother plant. After a while, miniature plants will appear on the runners and these will soon develop roots. At this stage, the runner can be separated from the mother plant and the individual plants can be removed from the runner. They can now be placed in different placements in the aquarium.

Easy
Short Description
This plant may take a while to establish but once it has it will soon spread over the substrate to form a carpet in the aquarium. They are very hardy and resilient to many of the diseases that affect other Cryptocoryne species. Many keepers will plant them in corners of the aquarium so that they can convert the fish waste and uneaten food into nutrients for this plant. It should not require any extra nutrients adding to the water column.
