There are several different species of Rhipsalis that look like that. The first picture is R. quellenbambensis, and the last is another species that looks very much like it. They aren't rare at all, but just not usually grown except by cactus enthusists.



All you need to do is take off a cutting the size you want that includes one or more nodes where the stems tend to branch off. Wrap this in some damp brown sphagnum moss, perhaps secured with some dental floss wrapped around this to keep it together, then just peg this into whatever part of the vivarium you want it to grow in. You don't need to include any roots, but if there are some pieces of root where you cut it off, so much the better. A cutting will probabaly root more successfully into your background media than if you attempt to transplant a division with roots already intact. If you do want to divide the plant from the roots, cut the roots back with sharp scissors as cleanly as possible, leaving only about 1/4th of their length. Shake off the soil. Then cut back the stems as well, preferrably at a node--wrap in sphagnum the same as a cutting.



As long as there is good drainage and the sphagnum is just damp and not wet, you shouldn't experience any rotting and the plant should form new roots and grow.
