Looks like Popeye, it may affect one or both eyes, appearing as if the eye has air or fluid trapped inside, around or behind it, causing the eye to enlarge and bulge out of its socket, as if under pressure. Duration of this condition can be anywhere from several days to several weeks.
A variety of physical injuries or non-infectious and infectious diseases can lead to this clinical condition. Typically, popeye in itself is not contagious to other fishes in the community.
To help aid in the continued health and healing of the fish during the course of this condition, oral feedings of foods soaked in selcon or another type of liquid vitamin, along with foods mixed with a broad spectrum antibiotic such as tetracycline, chloramphenicol or kanamycin are suggested. Eventually the eye will deflate, but may result in various conclusions.
Keep in mind that if both eyes are traumatized, the fish may not be able to see at all. The attempt to orally feed a fish with this type of severe condition is most likely impossible. Therefore, the fish should be carefully moved to a QT (quarantine tank) and treated with a broad spectrum topical antibiotic, such as skin absorbed kanamycin sulfate based antibiotics like Aquatronics' Kanacyn or Spectrogram, as well as Neomycin, and Maracyn or Maracyn-Two. Consult with your local fish store for more medication recommendations, as these are just a few on the market. We suggest that you do not treat the main aquarium, as many antibiotics can weaken or kill the biological filter.
