Green star polyps not opening

[Guss]

Hello all I got a green star polyp but hasn't opened it's been 5 hr or so. Not sure if position is correct. Dose it have to be directly hit by wave makers. I'll post a pic of were the gsp is and my wave maker tell me if I need to make changes plz. Ty
The gap is in the back on three glass my Wave maker is in the front bottom left.since it's a small tank I figure it should get enough flow or am I mistaken

They are indestructible, will open up later or within next day or two.

Agreed. They are very hardy. They do like a higher flow but I am sure just given more time, they should open up.

If you made any changes, my gsp is a bit of a whiner and can stay closed for long periods when annoyed.

Just give it time, my urchin ripped a chunk off and dropped it near my engineer goby's cave a month ago, he just shuttled it out today and it's still alive.

GSP is like that. Nothing changes and then it just closes up. Next day perfectly fine.
