Would anyone describe why Anubias' rhizome rots due to burying. Why does it need relatively aerobic conditions? << In the wild, Anubias grow in rocky streams, at the water's edge. There is not much sediment near the surface, and when the base of the plant is submerged, the water is often flowing quickly. So they are highly adapted to aerobic substrates, unlike many marsh plants which are rooted in thick mud.
