Duncan Dipping Help

[reef.fiens]

Hi, new poster but decent time user. Recently I realized my Duncan had been receding, but didn’t think too much of it because I just got a new powerhead. Then about 30 minutes ago, I realized it was spewing a dark brown/black mucus and realized a larger lesion/infection on it. I just finished dipping it in Seachem coral dip for about 30 minutes using the dosing instructions on the bottle. How often should I be dosing it now. I should also note that right now I do not have/ cannot get a quarantine tank for it, and am keeping it in my main display tank (25g Waterbox peninsula).

I've never had to deal with BJD so I can't say for sure what this is. It doesn't look good though.

*bump* for others to weigh in that have.

I feel like you are just seeing the normal tissue of a closed coral. Also when they spew that’s poop usually, only one hole in and out. Duncan’s sometimes close up like that and usually open back up within a few days if all is well. May have to adjust flow or move coral if it’s in the direct line of your new flow pump.

Definitely some kind of lesion or infection area because yesterday after the dip those areas slimed up a good bit. Its looking better today after I moved it to a frag stand underneath the overflow away from flow. What I can say changed is that the larger area has a more colored tissue near it.

Maybe damage to the coenosarc from the flow and then a stress response from the dip? Doesn’t look like a typical BJD or coral infection to me. It seems it was related to the flow change and dip. Any new additions or other corals with issues? Was the Duncan happy and growing before the change in flow?
The skin looks damaged/rough and annoyed. Which adds up with your increase in flow and lengthy dip in response to the coral being closed.
I’m sure you could take a sample and analyze it, but from experience this just looks like a ticked off coral.
I’m happy to be wrong, just offering my perspective.
A lot of people have issues with Duncans they attribute to infection. I have typically found them to be very hardy and robust with good disease resistance. This seems like a reaction to a change in environment. Not an infection.

Screenshotted typical brown jelly look. Also brown jelly disease is STINKY. Like gets on your hands and won’t wash off stinky. Not like healthy coral stink. I’m here for more replies. Willing to learn more if this is a disease.

No new additions so I’m definitely thinking mostly caused by flow and then it’s just stressed right now from the zip. It was growing tremendously months before I added the new flow, just gonna have to find a new spot that’s out of the flow for it once it heals up more. All of my other corals are happy, especially my torch. Also, thank you to the other user below who commented the picture of BJD, it’s definitely not that I haven’t seen anything like that other that one time it had the brown ooze but I’m thinking it was just pooping from stress.
