Stylocoeniella Nuked Overnight?!?

[KenRexford]

Weird, wondering if any thoughts. Tank is fine, but my stylocoeniella went from fantastic (relatively new addition, maybe 3 months) to white like overnight. It looked strange in one segment suddenly, then just white the next morning. It is about 4 inches from a candy cane and about 6 from a poci. The poci attacked a gorgonian nearer to it recently. Did the stylocoeniella get attacked? Did it self-destruct? Did it get COVID? What the heck?

All I can say is 'this happens'. If you look at my build thread - you can see lots of orange stetosa - in varying positions in the tank. One day - the edge of one was a little white - the next day it was completely white - at the same time - all the rest (which came from the same colony - and are years old - were completely fine). There was one small corner - of the 'dead piece' - that I fragged off - and glued into the same spot - its now grown back to the original size...

So - I've thought about this a lot:

1. Did I injure it somehow - while doing maintenance - that started an infection?
2. Is there some local competition going on with nearby corals?
3. Did something else change - like light in that location, or something like that - or a flow difference?

The interesting thing it cant be a global toxin, parameters, etc - or you'd think all of it would be affected.

Yeah, everything else is flourishing. If it wasn’t so sudden, I would just assume that the placement or my tank didn’t work. I added 3 anthias recently, but I cannot imagine that having any impact unless the LFS perhaps had something in their water that affected in very small amount the situation for the stylocoeniella. Maybe a dash of copper or something?

I guess one other thing - is there anything else you can think of that you did to the tank (water change, etc) - that might have affected that coral? I do know - that certain corals are more susceptible to change than others - lighting? etc?

Any mushrooms in the tank?
I have these green ones that I pull 4-5 out of my system every week.
The problem is they release and land on corals and sting them.
I had a few issues and finally saw one that had released and was on the coral.
I would never have know if I did not see them.
They have relocated many times in my system.
I started with only around 4-5.
To many to count now.

Everything was and is fine. I added anthias. Nothing else in the tank changed. Added Hydros Control 4 but control can’t do anything bad to corals. The only other weird thing was the attack on the gorgonian. That was weird. Candelabra gorgonian had one stalk bent over into the poci, like the poci used sweepers to grab it. That started dissolving that one branch, which caused the whole colony to hide. I separated the stalk, which died. The rest of the colony came back fine, except for some recession low on another stalk. I wonder if maybe the warfare caused the gorgonian to release it’s out chemicals which did not phase the poci but instead killed the nearby stylocoeniella? Friendly fire incident?
