I have a fish only saltwater tank. I have a Trigger, Blue Spotted Puffer, Dogface, foxface and Bristle Tooth Tange. The Dog face has had flukes for two weeks and he doesnt look like he's getting any better. I did two rounds of Prazipro now I'm using General Cure. Is this normal to be sick this long its been close or over 2 weeks? Yesterday he looked the worse he has in two weeks. Curled up under a rock and consistantly scratching all day. I'm scared to remove him and put him in a QT tank because I heard if you take them out of water your always risking them dying by blowing up but at this point if he doesn't get any better I am going to have too. Any advice would be appreciated.
