Firefish has weird white spot on eye!

[MV17]

I just recently noticed that one of my Firefish has an odd spot on his eye. You can see in the picture that the top one has the weird spot and the bottom one is fine. The same fish with the spot was getting bullied by my pistol shrimp for a little bit, but I think that has resolved itself. The only other things in the tank are the pistol shrimp, a watchman goby, and two clownfish. Let me know what you think.

I copied this from the net for your reference if applicable:

Popeye, also known as exophthalmos or exophthalmia, is more a condition than it is a disease. In saltwater fish 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.
Probable Causes
Eye Trauma - Trauma to the eye is usually the reason a fish has this condition when only one eye is affected. Eye trauma can be attributed to a scratch, scrape of bruise to the eye from encounters such as fighting with other fish, net abrasion, or coming into contact with a stationary object or organism in the aquarium, and may be bacterial or fungal in nature as well. In most cases where popeye occurs from eye trauma, the unsightly looking eye does not seem to affect the fish's overall good health. The fish appears to be healthy, its appetite has not diminished, and more than likely all tank readings will be normal.
Treatment - In cases where eye trauma is involved it is suggested to not remove the fish from the aquarium, unless harassment from other fishes is becoming a threat. Handling of the fish can cause further irritation to the eye, as well as additional trauma. In most minor cases the injury will heal in time as the condition is allowed to run its course. 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.

• In minor eye trauma situations, the eye will usually return to its normal appearance without blindness.
• In more serious cases where treatment is not provided or proves to be ineffective, the eye may appear colorless and gray, resulting in blindness to the eye, but is not necessarily fatal.
• In cases where one or both eyes have sustained severe trauma and treatment is not provided or proves to be ineffective, the eye(s) may burst or disappear altogether. This can be such a traumatic event that the fish may not recover and death will occur.

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.

Non-Infectious and Infectious Diseases - Trauma to both eyes can occur, but usually when both eyes are affected or more than one fish is showing signs of this condition, suspicion of a non-infectious or infectious disease should be considered. Popeye can be an outward sign that another disease is present which may be of bacterial, fungal or other origin. As examples, bilateral exophthalmia combined with ascites (a swollen abdomen from accumulation of body fluids in the abdominal cavity) is often seen in kidney disease. Popeye is sometimes considered to be manifested by an internal infection called Ichthyophonus hoferi (fungal disease), and is also a possible sign of Vibrio (bacterial disease). If the condition is resultant from a disease, the fish may succumb to complications of the disease rather than the popeye, if the actual disease is not properly diagnosed and treated.
Treatment - In cases where the condition is stemming from a non-infectious disease , follow the same treatment suggestions as with eye trauma outlined above. Treatment - If the condition is stemming from an infectious disease , carefully remove the fish from the main aquarium, to prevent spread of the infectious disease to other tank inhabitants, and place the fish in a QT for proper treatment of the underlying disease, as well as the popeye.

Other Suggested Causes
Nutritional deficiency, outside toxins or contaminates being introduced into the aquarium, a gas embolism caused by a sudden rise in tank temperature, excess copper, nitrate or ammonia, stress, and the gas bubble disease theory are other suggested causes as to why popeye might occur. Any of these factors may warrant closer evaluation if the condition does not seem to be associated with eye trauma or disease.
Poor water quality or environmental conditions have been suggested as other possible precursors to eye infections. If these causes are suspected, a regimen of 5 to 10% daily water changes may be warranted until the eye condition improves.
In closing, it is sad to say, but if a fish does respond to treatment and survives with both eyes blinded, it will most likely perish because it cannot see to locate food and will usually die from starvation. Under extreme circumstances such as this, where a fish cannot or will not eat, fish euthanasia might be considered at this point, rather than watch it starve to death. On the brighter side, a fish that survives this condition and ends up with one blind eye CAN go on to live a full life. We experienced the loss of the one eye scenario with a beautiful, large streamered, male Naso Tang we named Spike. With the initial onset of his popeye we did move him to a non-aggressive fish tank, because his blind side made it impossible for him to fend off aggressors that seemed to know he was at a disadvantage. After having popeye, which occurred from fighting with another fish, his eye deflated leaving it gray and colorless, as well as blinded. This in no way stopped him from eating either during the course of the condition or after it subsided. He would always keep his good eye to the front of the tank, and when he saw us coming would greet us for his daily hand feedings of nori. Boy was he a pig when it came to food! Despite the blind eye he knew every inch of the aquarium, navigated without hindrance and went on as if nothing had happened, so don't dispair!

This is not popeye but likely a scratch injury and as these fish typically dart into rocks and hide within, they make themselves susceptible to this type of injury. Often, allowing the fish to heal on its own will work but this fish seems to have cloudiness around the retina and should be treated in quarantine with Ethromyacin in the form of Maracyn AKA maracyn 1 for at least 5 days.
Ruby Rally may also work but will take several days to take effect

The general rule is - when only one of on one fish is affected, it is due to an injury. There may or may not be a secondary bacterial infection that gets involved. All other causes of eye issues involve both eyes, and the eyes of all fish (especially when they are the same species as here).

I would just watch this for now.

Here is an article I wrote on general fish eye health:

Aquarium Fish: The ‘Eyes’ Have it: A Review of Eye Health in Aquarium Fishes

Aquarists need to inspect their fish closely every day, for signs of impending health problems. It is much easier to resolve a problem when it first starts, than to attempt a drastic emergency treatment when the fish is close to dying.
