Anubias afzelii.jpgHere's a photo of Anubias afzelii, attached to a chunk of wood which is a good method. The true roots may grow down into the sand, but the rhizome must not be buried or it can rot.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
