Great to grow out of the tank (emersed). Does well this way if you are using hanging shoplights in a fishroom
This grows very FAST! I trim mine almost every month and have lots of cuttings. I stick stem in gravel and new plants. VERY Easy to grow. But, be careful it will be work to keep it in tank as it emerges. Adventitious roots from stems can be unsightly.
This plant does very well just left on it's own. It grows and reroots itself over and over until your tank is taken over. I love the way you can see the roots stretched out over everything.
