So over the last week these “blackhead” like spots have shown up on my nephthera. Some of the spots have gone away and the holes closed up but some more have started appearing further up the coral. It’s been open and seems happy but this looks bad. I haven’t tried to brush it off because there are literal holes and it looks like the black is dead tissue. I just don’t want to make it worse. Does anyone have any experience with this/ knows what it is? Can I just give it a freshwater or iodine dip?
Thanks for the help!
