Hello,

I have an Elegnce coral that is infected. The mantle is blown from the inside out, tentacles are very short.
Looks like ECS.
Does a FWD helps? I will place it lower in the tank, with less light and I concider doiing the FWD.
Any help because I never did this before and I want to save the elegance coral. It's a real beauty....

So this is what pinched mantle looks like?!

I sure wish there was a treatment for this other than a fresh water dip. Has anyone tried a short and dilute iodine dip, or maybe even peroxide.
the clam that I tried a fresh water dip on just stayed closed and I don’t see how it helped any. Clam died a few days after dip. @ReefSquad

That does not look like PMD. Rather it is an area of the mantle that is/was irritated. That patch of mantle lost most of the zoos and the pigmentation, but hardly retracted.
Not PMD. If this is the clam you are talking about then PMD is the wrong diagnosis, thus treatment did not help, but likely hurt.
FWD weather use it on coral or fish, only help with surface infection, not tissue infection. Whatever affect your clam above seem to be problem in the tissue.
good luck.

I have never FW dipped this clam. I showed a picture to someone whose owned a reef store for over 30 years and he said it was pinched mantle.
the clam I had that died was displaying retracted pinched mantle which started from the excurrent end like is typically seen. It had translucent tissue running down the middle of the mantle as well. It died a few days after I dipped it. This Derasa looks mildly better. I’ve been feeding a ton of Phyto. I’m hoping I can figure this out, because I got into clams because of this Derasa and have put further clam purchases on hold until I can get things worked out.
I thought Perkinsus also which lead to me believing that Perkinsus is not something we can keep out of our tanks as long as we are feeding our tanks foods with Perkinsus. (Certain fish foods)
Thanks for responding.

clam pulled through. I purchased a Squamosa, later another small maxima and now another squamous.

Doing this now Minh. Three healthy clams showing signs. All have new growth so I suspect healthy otherwise.

Sadly I didn’t take any pre-treatment pics. But typical PM on 2 3.5” gigas and an 8” squamosa was retracting mantel on 2 places. Suspect the squamosa was beginning to show signs so everyone got the dip.
