Hi everyone!
So I am back to questioning this plant's ID! Haha.
I no longer believe that it is Rhipsalis pilocarpa because since then I have bought an actual pilocarpa, and it produced pink hairy fruit at the tips of each stem.
On the other hand, this plant produces little greenish fruit spheres that are not hairy along the stem, not on the tips.
Any clue what it would be now? The puzzle continues. Haha.
