One of my females got chewed on a bit by one of her "sisters" about a week ago, no major injurys just a few tattered spots, so I took her and put her in a jar to treat her, her torn spots are healing very well with regular water changes and melafix, but she just came up with a problem with one of her pectoral fins, its normaly the very thin rounded triangle shape, but right now its like clumped together in a thin rectangle and she doesnt use it at all, I dont see anything on her body like ick or fin rot but I know it isnt normal or didnt use to be like this, any ideas?

Good thing she's in the QT because with only one pectoral, she'd have a hard time outrunning her sisters. Like trying to row a boat with only one oar. Hopefully the melafix will help her heal quickly. I've never heard of this kind of thing happening to a pectoral, it's definitely worrisome but I think that as long as she can get to the surface to breathe okay, she could probably live out a full life even if it doesn't grow back. She won't ever be able to go back in with her sisters and she'll need a smaller tank than a 10g but with care, she'd be okay. However, that's the worst-worst-case scenario and I'm still hoping that fin will heal and regrow. You might want to PM Oldfishlady because this is so unusual.
I was worried earlier because she got so sluggish and was almost floating but she has picked up now, she got excited over her mosquito larva dinner. She does still swim ok, just takes a little more effort. I'm just puzzled as to why her other fins are healing well and this one seems to be almost disintegrating.
Yeah, that is weird. I wonder if something more vital was affected in that fin, like more nerves or ligaments. Since the pectoral is so much shorter than her other fins, it wouldn't take much to reach those nerves. All I can suggest is warm water, lots of water changes, and observation. I'm glad she's got some energy back, though. Since it sounds like she was being picked on by her "stepsisters," you could call her Cinderella.
