I love mine, however the pulsing behavior seems to be sporadic or completely non-existent depending on light and flow. I got this one from my old LFS before I moved, mostly because it exhibited pulsing in their tank. It was in a fish system with basically no flow with T-12 lighting with a few other softie colonies. In my old tank with T-5 lightning it would pulse occasionally but in my current tank, it shows no pulsating whatsoever, however, it does react exactly like the one in the video when you disturb it. Love the pink color and how it's completely covered in fuzzy polyps, but if you're only goal is a coral that constantly pulses, just get Xenia.
