I've grown a few Rhipsalis over the years and still have three or four large plants but don't remember which ones they are. Some young plants look a lot different when they reach maturity than they do when they are young. I think two of mine are identical now that they've grown up. I used to have a small "Dancing Bones" but it never did much, did not seem to grow at all and I think it finally succumbed due to lack of care.
