Bulging eyes, known as Popeye in Rachow's Notho, is a critical condition caused by poor water quality, malnutrition, or infection. It's a serious sign that requires immediate attention. Owners should first assess the tank's parameters and recent changes before taking action.
Common Causes of Bulging Eyes (Popeye) in Rachow's Notho
Poor Water Quality
Most LikelyHigh levels of ammonia, nitrite, or nitrate can cause stress and lead to Popeye.
Malnutrition
PossibleInadequate diet or lack of essential nutrients can weaken the fish's immune system, making it susceptible to Popeye.
Infection
Most LikelyBacterial or parasitic infections can lead to Popeye as the body's response to infection is to swell areas, including the eyes.
Genetic Factors
Less CommonSome instances of Popeye may be due to genetic predispositions within the fish's lineage.
Physical Trauma
PossibleSudden impacts or fights can cause internal swelling, including the eyes, leading to Popeye.
How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Measure water parameters including ammonia, nitrite, nitrate, pH, and temperature.

Recommended: Water test kit - Inspect the fish for signs of injury or fighting.

How to Fix It
- Improve water quality by performing water changes and ensuring a clean tank environment.
Change 20-30% of the water daily to reduce ammonia and nitrite levels.
