Often I see a few bubbles form under the skin of 2 of my birdsnest corals. The bubbles either burst or go away and the corals seem just fine. I'm not too concerned just would like to know why it happens. I have a heavy sps dominant tank and all corals are growing very well.

I found this photo and post on this forum, but it didn't provide me with much information.
