Acro Frag Not Extending Polyps?

[GMGQ]

Yeah, I do notice the clown goby would sometimes peck at it. Sometimes I can still see the polyps in their little holes (like that picture), so at least it seems that the clown goby isnt having much luck at pecking them off.

I had red that clown gobies like hanging around in the braches of an acro. I never knew they did that because they liked eating it!

How do the retracted polyps affect the health and growth of the acro?

Xtasia, I tried putting my acro in a high flow area, but that made the polyps retract even more. It's only when I put it at the bottom, that the polyps will slightly come out... Weird eh? I read they like high flow and high light to grow. Go figure...
