Camera night vision strong invisible light

[littlehermit0]

Hello everyone, quick question
So I have set up a camera to check nocturnal animals, but this strong light appears at night vision, it's not visible to the human eye, but I'm scared that it harms my fish eyes, but they most likely ignore it and sleep, does somebody know if that is harming the animals in my tank?

That's probably the Near-Infrared light from the camera - there's not much research that I've been able to find on marine species vision and infrared, but there are a few species (like salmon, lampreys, and mantis shrimp for sure) that can confirmedly see it. Other species may be able to as well, but I'm not aware of any research showing it.

Regardless, other than making it a bit tough to sleep for species with IR-sensitive eyes, the infrared shouldn't harm anything in your tank.
