Black Combtooth Blenny face turning pale

[skyline377]

I have a Black Combtooth Blenny and every once in a while his/her face will turn white but more of the time it looks normal. Is it something I should be worry about???

No, when I had mine it would turn white with the lights off, or if it's Dark enough. But that's just my experience.

I had him/her for 2 months now and it's been doing well and I saw it this morning just chilling at the rock so I figure I take a few shots.

I've got a blue combtooth blenny that does the same. I'm certain it's 100% normal and just something that they do especially when the lights are off.
