Thanks for replying. Unfortunately, the hospital tank is so full of meds that it's too cloudy to see anything even when I do put her to the glass. So what I had to do is put her in a cup to check her out. She seemed strong enough to endure this stressor and was behaving like a normal fantail should by moving around and being very responsive.
Upon examination, I had seen no cloudy eyes, they are normal. No red lined or clamping of fins. She clamped her effected side on the first day of the trouble, but has not done so since.
No apparent infection around the gills, no discoloring other than the effected spot. It does not seem that her gills are puffy nor swollen and they seem to open and close normally to me. Her healthy side is nothing out of the ordinary, the scales are flat and pre-event normal. She does breath heavily currently, but the medicine water in the hospital tank is pretty thick in meds which cannot be good to breath in and I think that's making her breath heavily. Tomorrow is supposed to be the day I take her off of the med water, but I'm wondering if another 5 day treatment is recommended.
I looked at the blackness though a jewelers monocular and it's a small line, much like a cut and not little vermin. I'm thinking she could have cut herself on one of the toys some how and the cut had turned black in its healing. This blackness is at the bottom left of the infection and about 3 millimeter in length. It's a direct line as if is she swam by something sharp. I'm not sure what. Then again, I don't know how she got the round dot-like damage on her right gill either nearly 2 months ago. I'm thinking she could be more fragile than the others...
Looking more though the monocular, I still see her scales on her odd looking side and I'm not entirely certain that they fell out now. Do fish have a secondary line of scales under the ones that we normally see? Or do scales change color when they get an injury? They should be orange like the rest of her body, but they are white and not flat. They seem larger than they should be which would make me think it's the start of pine-cone disease, but that usually happens on both sides and not just one side, correct? I'm thinking she may have some internal puffiness or perhaps a bruise on her left side brought upon the cut.
Anyway I attempted to take a video of her, but it's very blurry, but I'm hoping it's of some help.

As you can see she does have a poo string, so she's still eating and pooing, although she won't really eat when I'm watching, preferring to spit it out rather than swallowing her flakes. She now hides when she sees me, which is not how she was like before as she was friendly enough, so I leave her alone in another room to get relaxation.
Anyway, her name is Mustache. Strange name, but she has a strange sense of humor. She has black pigmentation around her mouth that resembles a Mustache/Goatee. No where else, other than the very tips of her fins has blackness, so I really love the joke she's playing on us humans who has such silly things on our faces. I assume she's a she as she does not have an anal bump, which I'm told means the fantail is a girl.
Thanks for reading. I am wondering what to do for tomorrow as she is supposed to go off the meds. She seems to be healing well enough and is strong but shy. I don't see any cotton fuzz appearing and her fin rot disappeared, but I'm rather nervous about tomorrow and these things appearing.
