Yellow Coris Wrasse - Sudden Death

[tifa]

Hi all.

Woke up this morning to find my juvenile Yellow Coris Wrasse dead. No photos as the CUC didn't leave much behind. Two days ago, I noticed very faint white patches on her side (only visible under blue light), similar to the below threads:

Yellow Coris Wrasse - White/Opaque Spots/Blotches on Left Side?

Hey Guys - My Yellow Coris wrasse had some sort of opaque/clear-ish looking scales on one side show up soon after I got him. To the naked eye, you could only see that it looked like his scales were a bit opaque in a few spots on his left side. I had chalked it up to irritation from his burrowing...

Discolored scales in Yellow Coris Wrasse

Hello, I had in QT a Tellow Coris Wrase and more than a week ago I added it to DT. He stayed hidden in the sand for about 4-5 days. The is out and around for about 3 days now. Today during lights off I noticed something on his body. I need some help identifying if there is a disease or just...

I thought it might be from diving into the sand at night to sleep. Can't tell if it was an injury as I've never seen her get spooked. She seemed perfectly healthy, eating (fed 2-3x per day) and hunting pods all day. No flashing, yawning, or any sort lethargy. I considered the possibility of flukes, but with no symptoms, I didn't want to perform a FW dip unless necessary. Should I have done a FW dip? Pretty bummed to lose this fish as it was one of my favorites. I have a pair of clowns in the tank who show no signs of any sickness (no patches). Moving forward, what should I do? I quarantine/observe anything wet going into in my tank and alternate between feeding frozen and pellet, soaking in selcon every few days. I have a QT tank available and can dose Prazipro but don't want to stress the remaining fish any more than I have to. Any advice is much appreciated.

Do you have any pics/videos of the fish in question when alive? How long have you had it?
If I’m not mistaken, these guys are prone to uronema, which could certainly kill it in a matter of days.

I had a pair of Yellow Coris Wrasse and one of them suddenly died after about 1.5 years. DIdn't notice any spots. Did notice it being very lethargic a few days before he died (was the male). Great fish. They do eat almost any snail or hermit that i put into the 200g mixed reef tank though. Had to switch to urchins for hair algae control.

Strange, my yellow coris that I had for over 2 years never touched a single invert.

Photos aren't great, sorry. First one is from a couple weeks ago, second is from three days ago and is super blurry but shows she was eating well. She was pretty small, barely two inches. Had her for roughly half a year. I've never dealt with uronema (and hope I never have to) but didn't see any sores.

Mine never bothered the inverts or tankmates.

Any fish getting aggressive with it? Changes to the tank?
Pic doesn’t show much, but I don’t see any red sores you would see with uro (though those don’t typically pop up till late).

I see mine knocking snails them over and assume they are eating them. I also have a flame hawkfish - who definitely is very aggressive to inverts so same result either way

While I can't tell you what happened to your wrasse, it most likely was not Uronema - you would have seen red lesions, and Uronema is really rare in fish that have been in captivity for that length of time.

Wrasse was a model citizen and got along with the clowns, no bullying on either end. Added a QT'd coral a bit ago but that's all.

Do you think flukes/parasites are a possibility? And if so, should I dose Prazipro or wait and continue to monitor the other fish? I'm hoping this was an isolated incident, I read your thread on UNWD and am wondering if it was something like that, but want to make sure my other fish stay healthy.

For sure hawkfish are invert predators

I don't think this is UNWD disease.

Is the wrasse scratching/flashing at all? If it is, yes, you might want to treat with prazi for flukes. If not, I'd wait for other symptoms to develop.

Hawks and anthias and some wrasses do not blend well but without any signs of loss of appetite, heavy breathing, aggressions as examples- will be hard to pinpoint cause

Wrasse was the one that had passed, still trying to figure out why. Noticed today that my clownfish are breathing a bit fast (90-100 bpm) and twitching more than usual for the pair. I don't think I've ever seen the female twitch until today. Did a WC yesterday after the wrasse death so no ammonia spike. Still no visible signs of anything that I can see, but I've attached photos just in case. Female is the first photo, male is the latter three. Male has also always had that "dent" in his band. Both ate this morning, are not averse to light and haven't flashed. I've never dealt with flukes before nor have had a fish die so suddenly, but am hoping I can prevent any future loss.

Is is possible the white patches (linked in post) had anything to do with the death?

I don’t see anything alarming in the photos, can you post a video?

I too see nothing but could be post- death
