Yellow tang 12 days copramine

[iury Zardo]

Hi folks,
I’m beginning in the reef and in a couple weeks ago i did buy my first fish (Yellow tang). So I set up on QT abd put my tang in there, on the first day the fish eat good and on the 3nd day I start copramine treatment slow with 0.2 Pf copramine by day And I stopped add copramine when get 0.5 the fish was in the Qt with 0.5 around 11 days, yesterday many spots stains appeared on the fish's body and stop eat, then I decided to take a good part of the copramine, I changed 80% of the water and put carbon bag. So so today it has been 24 hours that the fish is without copramine and still have some stains, no eat and scratching. what do you recommend me to do?

Those red-ish looking areas can be a sign of a bacterial infection. Best to treat the fish with NFG powder. It works the best on those symptoms. Next choice is Furan2.

it's been three days since I completely removed the copper and my YT is getting back to eating very little and the red spots have decreased a lot, but YT is sewing a lot around the aquarium. my doubt is that this was not a reaction because of a long time in copper? where can i find these Furan2 pr NFG?
