Powder blue tang turned black and thin

[sivakumar12001]

Hello All,

My powder blue tang turned black and thin. Since 2 months I have this fish. Sudden ick attacked to my powder blue tang. Rest all fishes are fine no sign of ick. My problem with this tang I am dosing reef revolution parasite removal Since 7days now no ick on fish but it turned color black and it not actually swimming. Can any one tell me the issue.
I attacked a video please have a look.

I'm sorry about this. I'm not a fish disease expert but we have some members who are. @HumbleFish @Dr. Reef

Until they get a chance to reply. Here are some past discussions.

Most Acanthurus Tangs cannot manage Ich without proper treatment. This means pulling the fish out of the DT, treating with copper in a QT, etc.

What I believe you are seeing now is a "secondary" bacterial infection from the preexisting parasitic infestation: Bacterial Infections – Marine Fish Diseases and Treatment

I am not sure what the ingredients are of the med being used. Never used it so I can't comment on that. But all fish need to be removed from the main tank and need to be treated with either hypo or copper or tank transfer method. Along with running antibiotics to manage secondary bacterial infections.
Add selcon or fish vitamins to food and nori. This fish looks on the edge. Will need a lot of care to bring it back

Has he been hungry?
They can easily lose appetite during ick and treatments with Meds and that can be problematic.
I’d hypo him in new waters.
I’d add some selcon to some nori and keep him fed.
Certainly stressed out.

He is not having feeding.

Possible result of medications, even copper can lower appetite.
He must start for survival.
If your treating only for ick, 1.009 salinity (hypo-salinity) might be easier on him.

It is not taking feed

That's not good

I recommend you initiate the salvage protocol: *Salvage protocol for treating very sick fish*

And begin tube feeding:
