Sick birdsnest colony?

[Newbie4045]

My birdsnest was doing great but all of a sudden I started noticing this orange slime under the blue lights. I am able to blow it away and get it out of the tank but it keeps growing back anyone know what this is? It hasnt spread to other corals thank god but It looks like the coral is bleaching under the orange stuff when I remove it...

Kinda looks like some cyano. Do you have cyano in the tank and it possibly got blown into the birdsnest?

Best way to get a better ID if you could take some pictures under white lights. Kinda hard under blues!

No cyano anywhere in the tank! Everything else is thriving, just coralline covering all racks and the glass.
