Is my tang turning into a zombie?

[freddy]

In the past couple of months I bought a kole tang,seemed healthy next day looked terrible,just like that picture you found,started feeding metronidazole and focus in with their food,in about 4 days he looked like a brand new fish,I should have quarantined but didn't,and I forgot to mention my bicolour caught whatever the kole had,both are fine now,meds never affected inverts or corals,I also soak my food in a vitamin supplement and garlic quard,this is just my expierience,thouhgt I would share,does your fish have white stringy poop.

I would treate with Mardel Maroxy for saltwter. It may be a bacterial fungus.
You need to deal with this soon to save the fish,.

The reddish area could possibly be cause by ammonia. How many gallon is your QT setup and have you changed water since it's been in there? You need to stay on top of water change because this tank is most likely not cycled yet. I'd suggest you to do 30% water change for the next 5 days. That should improve on the water quality. And you should start a filter running for the tank. (That probably won't be effective for another 2 weeks or so and during this time you should do approx 20% water change ever couple of days)

Similar situation happened to me when I first started and I had a QT setup to help my fish. I had 3 fish in there and my yellow tang didn't make it because of the poor water quality. Now I run a much better QT / hospital tank setup to deal with things.

Your fish has hemorrhagic septicemia or a similar bacterial infection. You need to treat it with a anti-bacterial medication ASAP. Copper will do nothing to treat this.
