Lights that Sharks cant see?

[Kasey Grohowski]

Is there any kind of light/spectrum that sharks cant see, that humans can? So that you'd be able to see your shark more active since they are nocturnal.

I belive sharks aee diurnal or Crepuscular not nocturnal.

Low light am pm should suffice.

What do you mean low light? Lower on the spectrum?

No just low intensity.
A reef dusk pre dawn water colors would be blue.

So if I keep the lights blue then it should be more active?
