Spiral Coral Doing Poorly

[Squishie89]

So for the past couple of weeks I have noticed that my blue spiral coral has been loosing bits of flesh. This would sometimes happen if too big of a piece of food landed on it, but this seems to be something different as it is in multiple spots.




In the second picture at the top and bottom you can see what healthy polyps look like. The skeleton/base of the coral is back and spikey, you can see the spikes starting to show in other places as well. I feed the coral nutramar ova every day. I am going to try not feeding it for a few days and see if that helps. I do try and remove the brown bits when I can safely. I moved it from its previous locations where it had been for months as I had to clean my powerheads and I was afraid the angle or flow may have changed and caused this.
Would love to hear any thoughts or advice on this.

It's probably getting stung by the hammer sweepers. They can reach out a good distance.

As long as its not a smooth skinned acro you may wish to conider an iodine dip.

From the tiny bit of info out there I was under the impression these should not be dipped. The frogspawn is not as close as it seems but I will try moving it even further away just to be on the safe side.

Is that some sort of algae growing on it? High lighting, esp if flow isn't very turbid, can promote algae growth which will cause the flesh to die back. I've done a lot w gorgs but never worked w this one. Does it shed? Turkey baster blasting to help them shed seemed to work well when mine were having skin issues. Also, I have found that intense reef lighting can burn them (Caribbean ones anyway). The photo ones definitely like a lot of light, but TOO much light can definitely cause issues too. Never seen a gorg bleach, just wither away, then pop back to life when temporarily moved to shade and given a good blast.

I believe that is flesh hanging off. Not sure why it turned brown. I don't believe it sheds, never has before to my knowledge. I really have no clue what is going on. It has been fine for months and months. Has grown almost 2 inches. I have seen the flesh die off before when I tried originally feeding brine/mysis and the pieces were too big for it to eat and as the food rotted, it rotted the flesh. I then started feeding it nutramar, which is the perfect size and almost no issues since.
