So I was checking the clearance rack at Lowes and found this little guy. (and a couple other things...). First can anyone confirm that this one is actually R. rhombea? I saw an earlier thread where someone bought a similar plant at Lowes that was mislabeled and was actually something.

Second, My understanding is that it's an epiphytic jungle cactus, similar to thanksgiving cactus etc. Would the recommendations for potting mix, care etc. be similar to Thanksgiving cactus, which I already have and know what to do with, or is there anything special about this one I need to know?
