Help With disease identification

[azreefr]

I had 3 chromis and 1 carpenters wrasse in my DT for the past 5 months. About a week ago one of the chromis continued to swim in the same spot for a couple of days and stopped eating. I didn't see any markings, eye issues, streaks, etc but it looked like he had a big white poop sticking out of him at one point. He disappeared a day later never to be seen again. I have a mixed reef tank and do water changes and check parameters weekly. Everything has been normal. I have added a lot of frags lately. But all have gone through scrubbing and a 10+ min Bayer dip.

Two days ago I had a second chromis swimming in one spot for a day. Late last night I noticed what looked like brown marks on his body near his tail. This morning I saw red marks mostly on his tail. By the time I set up a hospital tank he was dead and being eaten by my hermit crabs. At a faster pace than I ever would have imagined. Probably 10 more minutes and there would have been no trace of him.

I'm really not confident that I know what this is. But I took a picture yesterday and another this morning that I will post. I would appreciate any help on the identification and treatment. I'm worried that my crabs may be spreading it and I would like to know how to treat my melanurus, carpenters, and the remaining chromis if needed. Thanks.

Also nematodes. (White stringy poop)

This has been going around lately...

Prazi treatment will get rid of it.

Thanks for the ID and treatment help! Sounds pretty bad. No easy way to get this out of my DT. I also read a couple posts saying that most tanks have this and it's triggered by stress. Is that accurate? Based on what I read I plan to wait and see if any of my fish show behavior changes, capture and fresh dip, followed by formalin baths in a hospital tank.

Though it can been seen in other fish under poor conditions, it is pretty specific to chromis. If you give up on keeping chromis, you probably won't see it again.

Since you are treating with formalin you can skip the FW dip.
