Ease of Keeping: Very easy.
Position: Floating, weighed down, tied down or one end buried in gravel. Rootless plant, so can be stightly hard to find the bottom end there is one at that!
A wonderful plant for fry to hide in and for betta breeding because the pair can always see eachother (so the male keeps his mind on the job) but very hard to get through (so the female or male does not get hurt by their potential mate). Be very careful when collecting it from ponds because it can be home to leaches and dragonfry larvae.
