•Symptoms: One or both eyes will swell and bulge out. It in itself can also be a symptom of Dropsy.
•Treatment: Usually not fatal if treated, but your betta might lose an eye. Conservative: If the swelling is extreme then use ES first. Perform 100% daily water changes. You may be able to treat the popeye with just Epsom and clean water. However, if the swelling goes down but the eyes remain cloudy/white, then switch to Aq.Salt at 1tsp/gal or use medications. Do not combine Aq.Salt with medications but you can continue to use ES during medical treatments. Medication: If ES or Aq.Salt do not do the trick or it is a serious case of popeye, then combine the ES with API Tetracycline, API Fungus Cure, API General Cure, API Triple Sulfa, OR Mardel’s Maracyn."
