I should have gotten a pic, may go back out and do that later tonight, sorry.
It is maybe 2-2.5 inches tip to tip, 5 legs, and peach. Sorry, but that is the best I can do at this moment. They had it in their coral area so I assume it is reef safe, as they keep the chocolate chip ones in the FO section. They had two in different cubes, one was on the sand and one was going up the glass.
Sorry for being so vague, but it is the best I can do. I am severely limited on starfish as I never really got into them before. Planning a in wall reef build and would like to add some when I do. IF they stay small I could get one now for the small reef I have though.
