Since I saw Xenia on the list, I thought I would toss out Anthelia as another similarly easy and adaptable softie. Xenia is perhaps the more behaviorally interesting one, but its less-stalky cousins can have a rather nice appearance too when placed in an area that washes back and forth gently.
This must vary by species/frag/moon phase/etc. The one frag of it I have was practically doing a jig when I took the lid off of the container it had been transported in. It doesn't bop about quite so much in the tank except when I turn the pumps off - then it goes nuts again. Go figure!
Bear in mind Xenia WILL sulk and won't start pulsing for a day or two.
