Blue tang eye swollen

[George]

If it's only one eye then it's most likely because of an injury. As long as she is eating and the water is clean then she will heal sooner or later.
If she is not getting better in a few weeks let us know and we can try to treat her.
Good luck!

something similar happens to my dogface once and a while I think he scraps it or bumps into a rock . When it happens I soak his pellets in garlic guard and it normally goes away in a few days .
