sun coral polyp extension

I have been wondering why my frags of sun corals open everyday all day,while the colonies only open at night or when food is added. Has anybody else noticed that a freshly cut frag seems to open up right away, if its not slimeing up. Please chime in to why they would open after fragging.

Are you sure they are the same species? frags are usually of dendros which have larger polyp heads - since they are branching they are generally easier to frag. Colonies tend to be Tubastraea colonies.

If they are the same species - it just may be the flow orientation. I have micranthus (black sun corals) on different parts of the tank - some stay open during the course of the day and other only open at night.
