I’m not sure what was wrong with this Lobophyllia, but it was free, so I had to try to save it. I always get nervous when I see a dying coral with a pink skeleton as it could be pink line syndrome (PLS). My guess is that it was just suffering from poor water quality due to the tissue recession around the skeleton.
Just in case it was PLS, I went ahead and cut off all the excess skeleton with a band saw. I then dipped it in a 10:1 tank water-to-hydrogen peroxide mix in order to treat any nuisance algae. Next, I dipped it in Bayer Advanced Insecticide for 15 minutes and followed it up with a 15 minute CoralRx dip. Within a month, it started healing up rather nicely.
After the first month, there wasn’t much else to do. It healed up on its own just fine.
It’s now starting to bud off a couple new polyps, and it has regrown over its old skeleton completely. Success!
