I honestly have no idea, but I think it could use a bit more sun. I assume it will always sort of trail, but I suppose not as much as it is doing right now.

I wish I was going shopping (plant sales???), but traffic does get bad.

Cotyledon orbiculata "pigs ear" in low light. These are one of the easiest succulents to etiolate but not that hard to fix. Simply make cuttings and start over.

I suspect the planter has no drainage holes judging by its placement on the wire rack? To allow any plant to thrive, succulent or not, it must allow for drainage. Also, what kind of mix are they planted in, it looks very dark and peaty?
