Description: The leaves of Indian fern are an unusual shape and the plant varies in size, depending on aquarium conditions. It does well if given good lighting and plenty of space for growth. Can be used as a floating plant. Plantlets are frequently produced along older leaves.

Cultivation of this decorative, undemanding fern plant is highly recommended. It will take up a lot of space within only a few weeks and will quickly permeate the substrate with its strong roots. Under good growing conditions, the leaves will have to be regularly trimmed and too large specimens replaced with young plants. Cultivation will succeed in both soft as well as hard, weak acid or slightly alkaline water. Provide a medium light intensity.
