Porites: die-off with pink border

[dendro982]

Did anybody experienced such thing with their porites:

Is it bruise, infection or environment?
Thanks.

There is a pink line disease that effects Porities species. Whether this is it, I couldn't tell you...

Check out this website. This is just from limited knowledge of this. It could be something eating it, or etc.

Most informative, thank you!

If it's not infectious, but stress-related (link (http://coral.aoml.noaa.gov/pipermail/coral-list/2007-November/005037.html) ), this is a good news - will improve environment.

I had a pretty nasty Nudi eating mine. When I manages to kill them and all there eggs, it grew back with a pink ring at the growth line.

How big the eggs are? Do you have a photo, by any chance?

The magnification on my photo is a as big, as I can get - eggs are not visible. On other porites too:
