So what did I miss? When I turn off the pumps, this coral stops looking cool and looks limp. I've never seen it "pulsate" the way that Charles' pulsating coral does :| Is it the particular strain? It was a hitch hiker on the Pink stylo that resides in the tank. I love the color but would exchange it in a minute for something that (1) wasn't a darn weed and (2) looked cool as it pulsated under energy of it's own!
