Midas Blenny stress stripes at night?

[ups.0fficial]

I’ve just noticed something a lil weird, when I turned off the tank lights for night my Midas Blenny immediately swam to his cave spot and quickly got his stress stripes, is this normal? Did I maybe turn the light off too suddenly? My tank lights have a thing where it flashes a white light for a second and then turns off, could this be part of it?

It’s normal. It’s a camouflage defense that they use when they sleep.

Thank you so much! I guess I’m a lil paranoid of losing him
