I think the one in this picture is just a junior sized version of the ones in previous posts. The polyps are quite similar to my other sarco pictured below. (before anyone asks, it is undergoing reattachment proceedings, because the stalk was getting long.)
Both these guys are under one 10000K 96W PC most of the day in a 50 gallon tank, and do very well. In the evening the 96W Actinic PC comes on for a few hours.
Just for fun I am adding a picture of my LTA, which is not supposed to survive PC lighting according to some folks.
