Unfortunately my naso tang has passed away and I’m looking for some advice to figure out what could have gone wrong. He was fine all day and then I suddenly saw him on the wave maker power head with blotchy white patches (doesn’t look like ich”

Once I found him I isolated him to a breeder box so I could then move him into my quarantine tank. Unfortunately he did not survive. I attached a photo of what he looked like when I moved him to the breeder box. Does anyone have an idea of what this would be? He had a slime coat, with fuzzies around his eyes. Was breathing very slowly before he died.

Wondering if this is a possible disease? However all my other fish seem healthy and happy. Or if this could be the result of a possible fight between tank mates. I acquired this tank when I moved into my home; it was here before me. And it is stocked with a few large tangs.

Any ideas to get to the bottom of this would be appreciated. Thanks!

I have not messed with the lighting cycle since I’ve had this tank. I am new to the hoppy and acquired it from my homes previous owners. It is a mobius lightning system. Lights are usually set to blue and are on a set schedule. I don’t know if changing to white would harm anything. It is a 125 gallon tank with plenty of live corals.

So sad! Always wanted one of those. I heard the wild caught ones are very picky when it comes to food, was that the case for yours?

We feed our fish a variety of pellets and flakes, mysis/brine shrimp. I am just following the instructions of the previous owners it truly is a marvellous setup and I don’t want to mess anything up. Any suggestions for feeding or anything else is appreciated!

Welcome to Reef2Reef!

It is really not possible to accurately diagnose a dead fish from a photo taken under blue lights.

I can make some general observations though - the fish has obvious skin lesions/discoloration and looks like it might be a bit thin.

How long had you had this fish? You mentioned something about the "previous owners". Did you buy this tank used?

Can you get some pictures of the other fish (video is even better) taken under white lights? The issue now of course is to ensure that there isn't some sort of disease t hat is spreading to your other fish.

I purchased this house and it came with the fish tank fully stocked with fish and corals. So I took on the hobby when I moved in a few months ago so I am new to all of this. I believe the naso tang was at least a few years old. With mobius lighting and all the corals, is it safe to turn the lights white?

This species is known to do poorly when first acquired, but your fish is past that point.

Turning the lights white to take pics and video is fine.

Was fish eating and breathing normal up to this point and when acquired??
Sorry to see and as mentioned hard to diagnose without notable symptoms

Yes he was eating and acting normally before. This was very sad and sudden.
