duncan dip

[LuckyReefer]

what’s going on with this duncan? is it like taking off a slime coat or something i’m not sure, this coral honestly has never opened for maybe a month or more it’s weird i have 4 duncan’s all look great besides this one, i have them sorta near each other so shouldn’t be any issue with flow or light. I decided to dip it using dip rx to see if maybe pest were causing it. i did this a while ago with a yaeyemenis frogspawn, and after dipping it it completely lost all of it polyps and now i kind of think it’s gonna happen to this duncan as well.

Sorry but it looks dead or almost dead to me. Your other corals don't look so good either. If you can share more details about your tank, Im sure folks can help. How old is the tank, what type of lighting and flow, what are the water parameters?

this is when my lights are off that’s why everything looks the way it does i’ll see if anything changes when my lights do turn on but that duncan right next to it will open super big and the polyps are long so i’m just not sure why my others aren’t doing the same
