Tangs Dying

[LokeLucky]

Hello,
I have 4 tangs in qt tank. Achilles, Scopas, yellow and purple tangs
Achilles and Scopas tangs both showed up with heavy white spots all over the body yesterday and Achilles died within 24hrs. Scopas is breathing heavy.
There skin shows lighter and faded

yellow and purple tangs have no signs of any disease.

can you please advise what this is ?

Sorry to hear and I must mention it is impossible to tell anything especially after 2 hours of death what the fish has. Achilles are very well known to contract velvet which spreads quickly. If you noticed any unsual behaviors when this began, with velvet you would have seen:
- Scratching body against hard objects
- Fish is lethargic
- Loss of appetite and weight loss
- Rapid, labored breathing
- Fins clamped against the body
- rapid breathing and mucus around the gills

Fish with velvet will typically stay at the surface of the water, or remain in a position where a steady flow of water is present in the aquarium. As the disease progresses outwards from the gills, the cysts then become visible on the fins and body. Although these cysts may appear as tiny white dots the size of a grain of salt, like the first sign of Saltwater Ich or White Spot Disease, what sets Oodinium apart from other types of ich is that at this point the fish have the appearance of being coated with what looks like a whitish or tan to golden colored, velvet-like film, thus the name Velvet Disease.

If you noticed these signs, you now know and does scopus display them at this time ?

Yesterday it was eating both morning (frozen) and evening (pellets)
I didn’t see them scratching again hard objects as well.

It’s trying to swim and not able to swim.
no mucus around gills as well.

Get your air pump running... Max aeration.

That photo doesn't show anything definitive other than a dead fish.

Can you take a video of the survivors under white light?

Ya air pump is running 24/7 on this qt.
scopas just passed and other 2 tangs (yellow and purple) don’t show any signs as of now.

any precautions I can take so this won’t happen to other 2 tangs ?

Identification is the first step.

Given two fish dying in quick succession, if you can rule out an environmental cause, I would get the QT up to therapeutic levels of copper, and quick.

Are you following the QT protocol we recommend? For example, are you treating with copper? If so, which product and what concentration?
Were the white spots small in size and large in number? Small grains of salt?

The Copper protocol is intended to combat both ich and velvet if either is present. An earlier post describes the symptoms to look for.

Edit: Also, what size is your QT? Four tangs in a small QT will often lead to significant agression which may lead to death.

Can you provide pics of scopas under white lighting .
Before administering medication, we need to confirm what you have
Generally a freshwater dip would offer relief but fish too far stressed to attempt it

Hello,
75 gallon qt tank.
It is drilled with 34 gallon triton sump.
I am not treating with copper, I am just using the reef medic by poly lab nothing else.

We had power outage in WA state last Friday and it came back Sunday evening so lights were off and only return pump, air pump and heater were running on generator.
I noticed lot of small salt grain like white dots on Achilles first and it was like that for 24hrs and died followed by scopas tang (this morning)

I purchased and installed 25watt UV just now.
I also have 2 cleaner shrimp 5 turbo snails and 1 damsel in this tank.

Salt grain notates ich, but again, really need to see pics of surviving fish to confirm.
