Help ID what killed my Yellow coris wrasse

PH 7.8
Ammonia 0
Nitrite 0
Nitrate 0
Temp 79
Salinity 1.026
75 gallon tank
Mixed corals
2 Damsels
1 cleaner shrimp
2 red bubble tip anemones
I had my 3 fish for 3 days, I got them all at the same time and acclimated them at the same time. My yellow Wrasse was doing fin the first day, then went into hiding the next day. This morning I woke up to find him lying next to my purple tip hammer coral. The damsels seem to be doing fine. My tank is 7 months old

This looks like an injury. If the fish arrived healthy than it is likely that the acclimation was stressful and the fish injured himself trying to adjust to new tank conditions. Yellow coris wrasses are notorious for very sudden and fast swimming actions when stressed or scared. The injury can be caused by swimming directly into the liverock, the glass, or not finding soft sand to burrow.

Thank you for your information

Uronema is also a possibility, wrasses have a susceptibility and it can kill fast. Red lesions are associated with it.

These guys can be hit or miss as young fish. The red could be injury or infection. Looks to me like infection (Uronema, Brook, Other) Make sure if you try again, you have a nice deep soft sand bed for it. They hide for the first few days.
Also, a qt time is helpful for these guys too. At the shops, they are in tanks where they are very stressed, usually. These guys need a sandbed and shops do not keep them like that. Causes extra stress and they need time to unstress. This goes for any sand dwelling fish.

Let's make sure it's not disease. I thought possibly uronema but I'm not a specialist. @Jay Hemdal @vetteguy53081 does this look like disease? (BTW: Jay, what is the group tag for the disease specialists again, I couldn't find it. There should be a sticky for that).

Edit: Looks like others chimed in as well.

I think it’s part of the diagnosis sticky.

Agree with others - its difficult to tell what killed a fish from a picture after death - because there can be hemorrhage, etc after death. BUT

The redness on the fins suggest a bacterial or other infection. The speed (assuming it was totally fine yesterday) - suggests uronema. Whether the fish was bullied by the Damsels, transit, etc - causing an injury - and then infection is also possible.

Lets talk about the other fish. Did you QT the fish before? Did you get them at an LFS - or were they shipped? How did you acclimate them? Any sense of disease on the others? If this was uronema. I would be extremely cautious about adding new fish anytime soon

Thank you!! For the life of me I couldn't remember this. It is now committed to memory.

Hi,

Given the fish’s species and history (new to the tank) and the way it looks, this is almost positively Uronema.
There is nothing you could have done to treat this and it probably won’t spread to the damsels unless they are chromis.
Check the library section here, I have an article posted about this disease.
