Stylophora Pistlillata disease?

[espenlg]

Anyone ever seen this?:

It's like a transparent bubble.. I've seen 2 of these in the colony, but there might be more.
I couldn't find any info elsewhere, so I would love to get some input on this.
Thanks!

I have no idea what it is, but I have had the same thng happen to a couple of stylos and an acropora.

It goes away with no harm done IME.

Wish I could help you more but ive been wanting to know what it really is for a while with no luck finding out. My bubbles never have been quite that pronounced...but the same thing for sure

hopefully someone will answer that knows as Id like to know too

It looks like a black spot under it so are you sure it's not just an air bubble from that "black" algae that often grows on stylos?

I'm pretty sure it's not an air bubble. I can touch it without popping it. It has some kinda skin if you know what I mean. The size is about 2mm btw..
