How about Singapore Moss??
Good morning Chris...
I prefer Singapore moss on driftwood. In some tank conditions it grows in thin, dark green threads. I have it several of my planted tanks. In some instances, pieces break off and attach to other plants. If it attaches to something closer to the light source, it can grow very thick branches. It's actually quite pretty. Anyway, I use black sewing thread to attach it to driftwood, the thinner the thread, the better. Eventually, the thread dissolves, but by that time, the moss is firmly established.
