Need help with Duncan coral !

[Looney Tunes]

Idk what happened woke up to it like this, closed up with some white strings coming from it, all my other corals are doing fine, does anyone know what’s wrong with it?

Can you list your parameters as well as a full tank shot?

Is that additional photo after or before it shrunk in?
A fish may have bothered it.
I would also recommend grabbing a nitrate and phosphate testing kit!

Will say mine closes up randomly. Probably got brushed on by a fish. They are fast growing within a couple months mine grew 5 new heads

You just woke up to it so last night its polyps were flowing? Or did it take some amount of time to get like that, how long have you had it? That doesn't happen to a healthy coral overnight unless something is eating or picking at it.

EDIT, actually it looks like a very fresh cut frag, that might be the problem perhaps

Yeah this morning it was like that but last night it was fully opened and fine. And going for a week now with it

So I’m still not sure what happened but it looks like it’s doing much better now, it opened back up ! :D

Not sure but my clown started biting my duncan (for months) and it looked pretty decrepit like that.
*I think the clown was just trying to get used to the coral as a possible host,,,all good now but it took some months for everything to work out

If bored, I have a thread on that here (maybe to skim through the progression of pictures, if nothing else):
