Common Causes of Curved or Curled Body in Twig Catfish

Poor Water Quality

Most Likely

High ammonia or nitrite levels can stress the fish, leading to skeletal deformities.

Nutritional Deficiencies

Most Likely

Lack of essential vitamins and minerals, especially calcium and vitamin D3, can cause skeletal issues.

Genetic Disorders

Possible

Some individuals may be predisposed to skeletal deformities due to genetic factors.

External Trauma

Less Common

Physical injury from aggressive tank mates or handling can bend the spine.

Parasitic Infections

Less Common

Parasites like anchor worms can cause swelling and damage to the fish's body, potentially leading to curvature.

How to Diagnose

Follow these steps in order. Stop when you identify a likely cause and move to treatment.

Perform a visual examination of the fish's body and spine.
Look for signs of swelling, discoloration, or irregularities in the shape of the spine.
Check the water parameters for ammonia, nitrite, nitrate, pH, and hardness levels.
Use a reliable test kit to ensure the water quality meets the Twig Catfish's requirements.
Recommended: Water test kit
