Echinodorus X barthii

Echinodorus x barthii is a decorative and beautiful solitary plant for large aquariums. The leaves change colour from dark-red in the youngest leaves to dark-green in the oldest. The colour develops well when the light intensity is high and there are sufficient micro-nutrients in the aquarium. A nutritious bottom and CO2 addition promote growth. This plant takes a lot of light from plants underneath, so it must be pruned occasionally. It used to be sold as "Double Red".
