I've posted a picture so there's no confusion in trying to explain what I see. If you look on her side fin its deep pink where it hasn't been before. She's in my 80gal with various cories, tetras, rasboras, glass cats and Trooper (my discus) there is also a syno catfish in there too. She is the only BN in there. Please if you know what this is or if I should be concerned let me know.

IMO this is normal and happens as the fish matures. It is more pronounced in males. Your fish looks healthy to me, I wouldn't worry about it. She looks like a nice quality fish. 
Thank you very much! I'm so relieved! I googled images for hours and only saw a couple with a similar presentation. When I clicked on those images there was no write up available. So I didn't know whether it was posted as an ailment or not. Thank you again. You've given me peace of mind.
