Okay, I’m grabbing a piece of wood today and a rock that I can probably attach them to as well as some taller plants for the backgroundAnubias have a rhizome. The leaves grow out of one side of the rhizome and the roots out of the other side. The rhizome needs to be above the substrate, but the roots can be under the substrate. But it is easier to attach it to decor so that the rhizome can't accidentally get buried.
