How can I move my favia?

[Eb0la11]

Ok, so I got this favia on a pretty low rock. Meanwhile I have a sandsifting goby that just loves to move sand all over the top of this rock, making a very nice den below.

Problem is, he dumps a lot of sand on top of the favia.

I'd love to move the favia but its pretty attached to this rock now. It seems to clear most of the sand off of itself on its own, and its been like this for like 2 months probably and is still growing, though a bit less now because of the sand. So it can survive here, but Id really like to move it.

Anyone have ideas how I could move it?
