Coral issues (new to the game)

[Sounds a bit fishy]

hi we recently adopted a tank of corals and I have noticed that the leather is looking a bit under the weather to so speak. We have kept fish but never corals. We have a natural seawater setup. Can anyone help me with him? I will post some pics. He has a white patch which is all slimy and he look like he is decaying. Help!! He is our biggest coral and don’t want to loose him.

Are those Zoas/Palys underneath the white patch stinging him?

Thank you I have placed a piece of rock under him to stop them from staining him. Are there any recommendations for how to deal with the white tissue? Shall I cut it off or just leave it?
