She was acting normally, but was swimming from one side to the other in the tank, so that's why it caught my attention, I thought she was spawning again, but then I saw that she wasn't moving this particular fin and had a tendency to tilt a little to the opposite side of her body when she was still.
I put her in a quarantine tank with 2 other cories that I've got yesterday, since I don't have any other tank that I can put her in

I've heard that it's not safe to use salt with cories. I'm sorry but I'm at loss here. I don't want to lose my cory!

I'm somewhat concerned too because I fed them live bloodworms 2 days ago (I never feed them live worms!) and yesterday I found that one of my female guppies had red streaks all over her body and had to move her to the hospital tank (that's why I had to put the cory in the Q-tine tank with the new cories)
Please help!!
