1 Causes and Treatment of Popeye in Arowana

Causes: 1) Old water with too much nitrate causes mild poisoning and popeye. 2) Too much high-protein food builds eye fat. 3) Rising pH and high alkalinity. 4) A single, vitamin-B-deficient diet. 5) Internal parasites reaching the eye. 6) Long-term strong light inside and outside the tank damaging the eyes.

Treatment: 1) Manage water strictly and change it regularly – good water prevents and treats popeye by diluting harmful substances. 2) At the first sign, use the ‘old three’ (heat, salt, water change). 3) Improve filtration and add nitrifying bacteria if needed to clear harmful substances faster.
