Pink goniopora issues

[jason604]

So I got this beautiful pink with blue mouth goniopora and it was fully open everyday for a few months till I moved it about 2 inches to help shield it more from flow because I changed my ****ty hydors to WP25s and a few Days after it never opened again. Been closed for about 2 months now. Is it because there's too much flow? But it's kinda shielded by rocks on both sides. I don't have an other places to put it other than sand bed but I heard just a big of sand in its mouths will kill it? Any1 got any tips?
