Common Causes of Curved or Curled Body in Glowlight Tetra

Poor Water Quality

Most Likely

High levels of ammonia, nitrite, or nitrate can lead to muscle damage and curvature.

Malnutrition

Possible

Lack of essential nutrients, particularly vitamins, can cause skeletal deformities.

Poor Water Temperature

Most Likely

Extreme temperature fluctuations can stress the fish and lead to body curvature.

Parasitic Infections

Possible

External parasites like Ich or internal parasites like tapeworms can cause curvature as a secondary effect.

Genetic Disorders

Less Common

Some tetras may be predisposed to skeletal issues due to genetic factors.
