I like this plant; it is extremely good for beginners. It was also my first 'True' Aquatic plant. I kept it in a betta side tank. It grew very well in incandescent lighting; glass pebbles; and fish poop. When my betta died; I put the sword into my planted tank. It was so robust; it started to look too full and weedy for my liking. Then I gave it away. One day I'll grow this plant where it fits imo.
These will grow tons of leave under medium-high lighting so I use T5 lighting in the big tank. If you want them to reproduce just increase the lighting to high and it will release a series of babies just like a Java Fern but I do not recommend you have a Java Fern in the same tank except very well covered by other plants since they like medium low light like from typical LED lighting. Regular water changes and either monitored liquid iron or root tabs should provide the iron that SHOULD be missing from your slightly hard water. Tend to collect algae even when the tank surface is clean but expect to see your snails, shrimp or some fish eating any algae off their wide surfaces.
