Becoming a sought after moss. As far as mosses go, it is one of the more demanding varieties. If left to float, will sink on its own when the mat becomes heavy. Can be tied to wood or rock. All in all a versatile plant so long as its high demand on lighting and CO2 are met. Not compatible with duckweed. Usually algae free, but can be lost to hair algae. Great in fry tanks as the moss can provide hiding places for fry.
