Aquarium equipment

Great background plant whose deep green leaves contrast nicely against other plants.

Plant care

Does not require CO2 fertilisation, however, additional CO2 speeds up growth even further. Propagation is very easy, as in most stem plants. Just cut off a part of the plant, e.g. a lateral shoot, and replant into the substrate.

Water care

It is exceedingly well-suited for enriching the water with oxygen, for binding nutrients and to compete against algae in an aquarium. Colder temperatures and hard water rich in calcium are preferred, however, it tolerates higher temperatures for a short time without stopping growth.
