The Rotala indica benefits from regular additions of CO2 growing more quickly and spreading across the surface of the water.

Plant care

In its submerse form the Rotala indica is a relatively fragile plant that should not be included in an aquarium with overly active fish that may damage the fragile stems. In the aquarium this plant easily propagated by cuttings.

Water care

The iron rich fertilizers, and trace elements are useful to produce intense coloration and vigorous growth.
