Marrone I have had those grand palys and just sold my last one. And YES they look very similiar to that when they are smaller. When they get larger yes they look like the pics above. They are a rarer paly and I wouldn't get rid of it until it grows a little to be sure what it is. If it is new rock just added to the tank it might not have had a chance to color up yet. Most LFS keep their rock in seperate tanks with low lighting and would have made the paly lose color. I would give it a month or 2 and see what it does from there.
