This is my girl Fiona. I got her around October and she is usually extremely outgoing, happy, and active. I noticed she was quite tired lately and realized she has a little boo boo on her fin. It makes her side protrude out a bit. I’m thinking it could be a cyst? But hoping it’s just a little scratch. It’s been here for about a week and is affecting her usage of this fin, so I’m wanting advice. Been trying to do more frequent water changes and use aquarium salt as well as provide bettafix. Any other suggestions? She is swimming mostly with the other one, and it seems to be making her pretty tired.
