Popeye is a symptom of an underlying disorder in the tank. It can be a result of trauma or infection. Most cases can be managed by maintaining water quality and a broad spectrum antibiotic. Quarantining as you have done is always a good move. Check the tank for any furniture/décor that may cause injury. Check the water chemistry, filtration and temperature next. Any imbalances can predispose a fish to illness. Partial water changes can be done to improve quality and correct imbalances. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. Maracyn Plus or Kanaplex can be found in the aquarium section of the local Petco or fish store. You can use either, in addition to plain aquarium salt (NOT table salt), to treat. Dissolve 1 teaspoon of salt per gallon of water in a cup of tank water and gently pour it into the tank. Treat for 10-14 days with salt then perform partial water changes to decrease salinity. Treat only the amount of water going back into the tank with salt to avoid overdosing.
