Hi, I saw in one of Amanos tanks that he had Riccia that took ahold of driftwood. I want to try Riccia for the first time and want to either put it on some wood or better yet get it to hold on some rocks. How is this done? Should it be tied down like Java Fern? What light, water parameters, and fertilizers does Riccia like? Thanks. John There are always exceptions to the rules.
