Swimming against rock

[Phivo]

I noticed my fish swim against rock when the light comes on in the mornings do you know what could cause this behavior.

Ive ruled out parasites because they act normal and look fine during the day they only act like this when the lights come on

My ammonia is zero
I use R/O for my salt mix


I have a royal gramma
And a humbug damsel

I could be something with them being temporarily blinded
