Goniopora Emergency?

[Larry101]

Good morning! I purchased a rather large goniopora colony last week for my nuvo 15, however it’s been 6 days and only like 1/4th of it has ever extended its polyps fully. I have a picture of the tank during the day to see it, and just last night I was looking at it and turned on the lights to take a picture. The Goni looks like it’s bleaching or something in the middle, and I don’t know what’s wrong with it. Thank you so much for all your help

Thats a beautiful goniopora. The others look healthy and thats a localized spot, keep an eye out for little pods on the skeleton if you can. I've been seeing interesting information lately about parasitic copepods that feed specifically on goniopora. Not saying thats your issue but something to keep an eye out for.

I think it might be getting stung from the goni beside it.
