Leather Coral Help

[Davehla]

Hi all,
My leather coral started getting spots on it earlier this week. Do you know what they are or have any suggestions on how to fix it?
Thank you!

Something is either stinging it or really bothering it. Those look like necrotic areas. Can treat with some iodine. Do you have the ability to remove the leather for a dip? If do, I would put into a container and dip in iodine for 5 minutes or so. Just help heal a bit because bacteria is a concern now. If not, make up a concentrated dose and turn flow off. Then try to get the iodine directly on the coral on those spots. Should not effect other corals if you are careful.
