Who knows what this is?

I picked this guy up at the LFS b/c he looked interesting and no one knew what he was. He was a hitch-hiker and just got put in the $10 rack (got him for $5 though!) I've had several different opinions on what it is, no one really agrees though. It changes from a dark orange to green color. It has little spikes that seem to surround a mouth of some sort. I'm not sure if it a an LPS or SPS. Heres a picture:

Looks an Echinophyllia. Pretty hardy coral. I have one that survived a timer problem. Halides were left on for two days while I was out of town.
