Since you've already moved her, just leave her there. I don't think she'll eat peas, but you can give it a try. Give the epsom salt a try, but don't start any meds. Treating with meds blindly typically doesn't help and typically makes things worst. I prefer the watch and see, and sometimes just hope for the best approach. Fortunately, I haven't had to deal with many ailments during my time in the hobby, but I've certainly read about plenty via these fish forums.
Also be aware that moving a fish can be very stressful, and you should do it sparingly
