Description: This adoptable and undemanding anubias has become more widely available in recent years. It will grow quite tall, so is best suited to the background of the aquarium. The thick, leathery leaves are terrestrial in appearance. The Congo anubias can be used in bog or marsh conditions, or in an open-topped aquarium, where it may produce leaves above the surface.
Anubias heterophylla is a slow-growing and relatively rare marsh plant with a good adaptability to aquarium cultivation. It is highly recommended for spacious paludariums. In the aquarium, the species will remain considerably smaller than if growing emersed. Depending on the aquarium size, this Anubias may be used for the middle and rear planting zones. The plants will possibly grow best in soft water, even though healthy growth can also succeed in water of medium hardness. A medium light intensity is recommended. Propagation is through partitioning of the rhizome. Sexual propagation by seeds is possible as well.
