Common Causes of Cloudy Eyes in Dwarf Puffer

Poor Water Quality

Most Likely

Infection

Possible

Bacterial or fungal infections can affect the eyes, causing opacity and a white film.

Stress

Most Likely

Stress from tank mates, overcrowding, or rapid changes in water parameters can trigger cloudy eyes.

Poor Diet

Possible

Insufficient nutrients can weaken the immune system, making Dwarf Puffers more susceptible to eye infections.

Genetic Factors
