Natural History
There are at least three different Riccardia types in the aquarium hobby, labeled in the trade i.a. Riccardia chamedryfolia and R. graeffei. However the correctness of their identification is not yet proven. Therefore we use the name Riccardia sp. "chamedryfolia" for the type that is labeled R. chamedryfola in trade. It develops quite firm, narrow, rather ascending branches that are more or less pinnately ramified.
Pro Tips
Good lighting promotes compact cushions with densely ramified branches. When the cushions have grown very big, they will detach from the substrate sooner or later. Therefore timely trimming is recommendable.
