Anubias minature is the smallest anubias we have seen to date. The leaves are roughly 10mm diameter and most have a rounder shape than something like Anubias bonsai. Just as easy to grow as other anubias, simply tie to wood or rock for best effect. Don't plant it in the substrate or it will rot.
Looks best in smaller aquariums due to it's petite size, but it's a really lovely plant.
