Upset Sword?

[-FighterFishh]

One of my swords seems to have her dorsal fin down, and I can't work out why.
She's eating and pretty active, but she seems at her happiest in the morning.
All my levels are normal and she isn't being bullied, either.
Any ideas why she's like this and how I could make her happier?
Thanks!

The fish in your post looks just fine to me. She is a nice looking twin bar tuxedo platy with the proper proportions for her species and nice erect fins.
