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.
This form of Sword is a fairly new addition to the aquarium hobby, unlike some of the swords; its leaves tend to be longer and slimmer. It can be invasive and plants can literally appear in the tank overnight if it is given the correct growing conditions. Yellowing of the leaves is a sure sigh of iron deficiency so always keep a watch out for this but it is very undemanding in all other aspects.
