Unsual Euphyllia Deaths

[TangoTang]

About three weeks ago I bought corals from a break down and made sure to dip each one. This coral list included acros, montis, acans, favias and many euphyllia colonies. After about a week in my tank, my existing colonies of euphyllia began showing symptoms of what seemed like bailing. I had recently moved flow around for the new corals so I believed it was that and moved the affected corals just writing it off as such. After the death of two heads of torches (about 5 inch tentacles when fully extended) falling right off the skeleton and a currently dying hammer, I decided to look around my tank. I found these very weird looking worms?? in my montis which has recently been loosing some color as well now to mention it. I also experienced the death of a very healthy duncan and my elegance is just dying at an alarming rate. All of these corals were doing fine.

I have attached photos of what I saw in hopes that anyone can help me.

On the dead skeleton I cant see anything that seems like EEFW but im not ready to write anything off yet. What is most interesting to me is that it seems to only be affecting the corals I had in the tank, not the newly introduced ones.

Please anyone that can help me beat this or can offer some sort of advise, I would highly appreciate it

Can't tell anything from the images other than the worms (?) look icky. I had a hammer displaying symptoms of brown jelly disease and a colleague recommended that I immediately treat it with Polyp Lab Reef Primer in order to prevent it from spreading in the tank. I did that and while the coral is not back to it's former glory, it's on the road to recovery (it was also near an elegance and another large hammer).

from what ive read brown jelly disease should show some residue or brown film correct? I have not seen this in any of the corals. In fact the only one that seems to be "dying off" is the elegance, the photos I attached of the hammer is showing how the tissue has just fallen off the skeleton, like the photos of the torch heads just off the skeleton. Ive honestly never has tissue just, nevertheless at this rate. Ill try to get better shots of the euphyllias

That's my understanding, yes. That particular hammer was doing fine until I thought it was in a bad spot and thought I'd relocate it. Well, over the better part of a day it got moved several times as various fish and inverts kept knocking it over. Then it started deteriorating. So sometimes just trying to move the corals around can have a detrimental and opposite effect.

I'm at a loss to offer anything other than perhaps suggest you also include your most recent water parameters.

I hope these help a bit to ID anything. I can’t seem to see anything on the corals themselves.

the last two photos are of what I’ve been experiencing, which is the rapid loss of tissue

Hi, I think I see on the 1st few photos something which can really kill your corals when it just going on them (the slime it can produce can sting them to death, the tissue later on look like STN ...).
The pest I think off is

Benthic ctenophores​

Google it later on, I can give only few links to read about. It's something going mainly on softies and LPS (have seen it few times), it exist in many forms and many SP as well:
Link 1 , Link 2 , Or Platyctenida (similar to them) , Link 3 , Link 4 , Link 5-other , Link 6 , Isn't Beroe ovata , GOOGLE Link

Hope that help. If I see something wrong, please post only the photos (and if can put them in circle) the worms.
Good Luck

This is incredibly helpful! Thank you so much

After taking one of the infected corals out of the tank, this is what I found. The orange thing was throwing out a white string when touched. I removed as much as I could. I also found some on the elegance which I had to remove. Let me know if any of these photos help. Maybe if there’s an ID there’s treatment for it?




Here’s what I saw in the elegance that took out of the tank

Ok so I think this is the best photos I’ve taken of what I believe is going on or for the most part the strangest thing I’ve been seeing in my tank. Most importantly, this was the location where the torch that died and the hammer that I relocated were.

they seem like nudibranch to me or some sort of EEFW or maybe even
Benthic ctenophores as stated above.

what is the best way to eradicate this, either removing them or treating the tank entirely.

I hope these photos are helpful, as everyone in here has been very informative so thank you for that! I want to catch this before it gets somewhere worst

from the photos here if that's moving is kind ot flatworm, or ctenophores, the prev post the photo with the purple, if that one is moving is 99% benthic ctenophore, as I few year ago and when I try to take them out with tweezers, it just split and regrow another 2 from that split. it realise in the water long strings like on which it catch food, but on that strings have attachments like, where are stinging cels to stun. If they touch coral it can sting it really much.
I use turkey baster to suck them, as picking wasn't working. about treatment I wasn't able to find.
If you check some of my posts near year go you'll find it in the ID section.
