Clownfish sick

[vyerous]

Hello everyone. I have been QTing a pair of true percs for about 2 weeks now and things have started to go down hill. The female came in healthy, full of life, eating and pooping no problem, today she hasn't really eaten any food and her poop is stringy. I also notice a thin small white line on the tail that has become more visible. I have been told to keep an eye on it and check to see if it becomes fuzzy (ok?) is there any disease that has been known to cause a horizontal line? I don't believe I have ich, I don't see a white film on either of the fish. The male seems to be doing just fine, eating, pooping, its just the female that is sickly. What do you guys recommend as far as treatment goes? Will this internal parasite pass or should I treat? If I should treat please recommend with what? Also is it better to medicate with food or dose the water?

Thanks.

In the top photo you can see a little raised spot at the top by her fin, any ideas on that?

In the bottom picture you can see the line that is only on one side of her tail.

Sorry for the crappy pictures, just snapped them real quick to show what I am talking about.

Was there any fish in the QT before the perc's? If not check your ammonia.I keep several small ocellaris In my qt tank to keep it cycled.When I bring home fish I simply remove the same inch count from the QT....No Ammonia spike.

I'm doing a large water change when I get home, last time I checked ammonia was at 0. No fish in the QT before plus it was thoroughly cleaned. I keep a filter on my display tank and let the filter media become established then I put it on my QT to help convert waste into nitrogen gas.

How did the 6 clowns die? All similar? If so then it was something you were doing, maybe params not good or a disease in your tank.
