Bubble coral acting dumb

[kamatisyahoo]

Hi everyone. Had this bubble coral for awhile. Then it suddenly showed his skeleton from the mouth, the next week it recovered. Now these past couple of days its showing the skeleton again. What would be a reason for this?

Have you changed your flow recently? Bubble corals are notorious for having their skeleton peice their flesh during transit but if it's been just sitting in the same spot my guess would be possibly too much flow on occasion?

I might have moved my powerhead and maybe it changed the flow. You think its getting more flow that usual?
