Pet's info: Fish | Unknown - Fish | Male

I have a Betta who is recovering from stress and had discoloration, but his color is slowly coming back. Except, I first saw this white line near his right eye. I gave him medication, but the white spot has gotten even more white? Could it be popeye and how should I treat it?

Maintain pristine water quality via filtration and regular partial water changes. Monitor water chemistry to confirm 0 ppm ammonia and nitrites with nitrates at 20 ppm or less. Keep the water temperature between 78F and 80F to prevent stress. You can use plain aquarium salt (NOT table salt or Epsom salt) as a general tonic to reduce stress, improve gill function, treat minor infection and aid in any recovery. 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 then reassess his condition. Do not treat with salt for longer than 14 days at a time. Perform water changes afterwards to reduce salinity. Use only aged or conditioned water that is temperature matched to prevent stress or shock.
