Kuhli loach

[Raul Javier]

Hi
Why is my kuhli loach loosing colors?

 

[CassCats]

They often fade like this when lights are turned off and will look like this when you first turn on the lights.
Or if he is stressed by tankmates or his environment.

What are your water parameters?

They are ok . Ammonia 0 nitrites 0 nitrates under control
