Owners should first ensure the fish is in a stress-free environment with optimal water parameters and a balanced diet.

Yoyo Loach Pale Color: Common Causes

Stress

Possible

Stress from aggression, overcrowding, or changes in the environment can cause coloration to fade.

Genetic Factors

Less Common
