Nice and small little plant. Easy to grow and maintan. Not the type for reducing nitrate but it helps in a fair bit when you have alot of it.Best to have it on drift wood or lava rocks tied down on it.You will need to have a constant cool water.Not chiller. Makesure that you put it in a dechlorinated water. Water which is 'stable' and quite cycled. You can fert the plants with seachem flourish once a week.
