I do not know what cactus species this is but it was planted for about 3 years on now in this black Far East Flora planter without drainage holes. The fleshy stems just kept on extending longer and longer and its prickly spines are really nasty.I had it placed under roof cover so that it would not rot when exposed to rain during the wet seasons. The strange thing was, one pot of them had the cactus soaking in standing water, which I believe the workers fail to check every time they water the succulent plant.
