Anubias barteri var. nana Jack Cocchiarella Show Substack. Anubias barteri var. nana is a small, attractive plant which thrives in all conditions. It originates from Cameroon and will reach 5 10 cm height. The rhizome will be 10 15 cm or more. It grows slowly, and the leaves survive for several years, giving slow growing algae the chance to become established. The best result is achieved by planting on a stone or tree root. Fishing line can be used to attach the plant until it gains a hold. If planted on the bottom the rhizome must not be covered because it tends to rot. It flowers frequently under water. It is not eaten by herbivorous fish. Product Details: Type: Rhizomatous Growth: Slow Light: Low Origin: Africa Height: 5 15+ CO2: Low
