Duncan Coral issue

[Bnortz]

My neon green duncan has not been doing so well in the past couple weeks. I acquired this with 5 heads a month and a half ago. It did really well for 2 weeks roughly. Was open and fully extended. Then one day it shriveled up and barely opened. I thought may e it was getting too much flow do I moved it to a lower flow area. Now two heads seem to have decayed while the other 3 are barely opened but are clearly living. Should I dip it with lugols then move it again? Any other thoughts? Thanks!

What kind of lighting is it under? I wouldn't move it around to much, from what I have seen these are pretty hardy corals.

I have one duncan that likes high flow and one that likes a little calmer waters. Sometimes mine will close up for a few days but no longer than a week just because, then it opens back up and looks as happy as can be.

Under 4x54 T5s...should I try the dip?

Same thing appended to me and my LFS told me to coral do him. It was too late they all decayed

try feeding, when mine starts to close i feed it and its back to normal
a short tentacle plate coral will do the same, (kinda like a sun coral,but doesn't require as much food

Find a flow pattern that he likes. I have a 10 head bight green short polyp Duncan that was on the sand bed with moderate to low flow. He would hardly open up for almost a month and kept waiting for him to respond. I was pretty bummed about it. Then on a whim moved him to a very high flow area, and "Boom"... Fully extended practically 24/7

I guess I'm gonna try the dip and move to higher flow

Have you been target feeding it at all? Mine is in a moderate flow area under 6 T5's...all coarls are different...

GL though...

I've seen this issue before. My advice would be to frag the "rotting" heads off if possible. Maybe a quick revive dip for good measure. I've had best success with this coral in moderate light and moderate flow. They can be sensitive to temperature changes especially when the temp gets approached 80. Other then that, they will pretty much always feed if you take the time to spot feed.

How should I go about "fragging" these rotting heads off? I'll also try spot feeding
