Fox face turning black and white when light gos off

[Canterthefishman]

Hi I just got a fox face and whenever the light is off or he is under something shadowy he turns all black and white. Is this normal?

Thanks!

Completely normal. Mine does the same

Sleeping. Normal

I agree. Very normal.

I don't have one, but I'm just really curious...why and HOW do they do this? Does anyone know?

Totally normal behavior. Many fish do that. Some of the neatest markings on my Midas blenny appear when it perches in different spots at night.
