Anubias nana
Anubias Barteri var. Nana, originating from Cameroon, is a charismatic plant that blooms in any weather. It reaches 5-10 cm in height and its rhizomes stretches to 10-15 cm or more. It grows gracefully, and its leaves survive for several years, giving the slow-growing algae a chance to establish. To achieve the utmost results, plant on a piece of stone or wood. A fishing line can also be used to bind the plant until it gains a hold. Do not cover the rhizome as it will lead to rotting. This can also be planted underwater — it is not eaten by herbiverous fish.
