When only one of your fish’s eyes is afflicted by the disease, it’s known as the unilateral pop eye. It usually begins as a bit of protrusion, but it will get larger over time if not treated appropriately. Unilateral pop eye in your swordtail might occur due to bad genetics or normal wear and tear.

When the eye on only one side of your fish bulges out, and there are no other visible indicators of disease, this is known as unilateral Popeye. An accident, poor water quality, or a genetic abnormality causes this type of Popeye to develop over six to eight weeks. It eliminates waste from the fish’s body cavity without causing pain.

Bilateral Popeye

Both eyeballs protrude out due to an infection or injury that causes fluid buildup in the fish’s body cavity, which is bilateral Popeye. If one of your fish’s eyes begins to bulge, add one teaspoon of Epsom salt per five gallons of water to assist relieve the discomfort and remove any parasites or toxins that may be present.

When both of your fish’s eyeballs protrude out, it’s usually a sign that the illness has traveled throughout the body; otherwise, it would only affect one eye at a time, as it does with unilateral Popeye. The side of their face opposite their bulging eyes will likewise appear deflated.

Popeye is a condition in which a fish’s eye swells. Poor water conditions or co-infection with another sickness, such as bacterial infections from “red leg” and columnaris, are the most common causes. Pop-eye can, however, be produced by genetic abnormalities in the fish in some situations.

  • Concerns about water quality (e.g., ammonia, nitrite, and nitrate toxicity; low dissolved oxygen)
  • Infections caused by bacteria (such as columnaris and “red leg”)
  • Inadequate filtration with an overabundance of fish in an aquarium or pond
  • Genetic abnormalities (rare in fish, generally only observed in goldfish — but can also occur in platies.)

At the same time, the ill fish will still be able to eat. Salt will not assist if your swordtail fish’s Popeye has progressed to the point that it can no longer swallow.

In situations of Popeye, Epsom salts are also beneficial. They contain Magnesium which can help to ease swelling.
