Jungle Cacti ID

I rescued this little guy a few years back from Home Depot. The poor thing was dry and shrively, so I bought it. I potted it into the pot it's in now, and I have no idea as to what the soil is anymore. It never really did much, but when I put it outside a month ago, it grew like crazy and doubled in size. Here are some pics:





Any ideas as to what this thing is?

A person on another forum ID'd it as Rhipsalis crispata, and I think that looks more correct.

Actually, R. crispata, R. pachyptera, and R. oblonga are almost identical except for flower. It is one of those 3, I said pachyptera because it is the most commonly found in general garden stores.
