Graveyardworm: Thank for the ID
Bluenassarius: Gorgeous, slow growing, easy to remove, and unlike many of my other macros not a threat. Now if I can just figure out how to propagate it. It has a very large holdfast, I wonder it a piece of it attached to a rock would grow a new colony?
Origin of these two colonies is InlandAquatics of Terre Haute , IN (USA).
