I love the green color on this beautiful stem plant from South America. Tonina Fluviatilis blossoms like a little star, that can be positioned in mid tank or background depending on the size of your planted aquarium. This little star demands CO2 injection, adequate lighting and cool water. With ADA's Amazonia II Aquasoil substrate system, they will be a rewarding visual treat for any enthusiast. Recommended for expert class.
