In recent years, scientists have discovered that not only are some species of fish able to see light in the UV spectrum, but that their UV-detection abilities are actually quite good. As a result, using UV coloring has been heralded by some manufacturers as the latest innovation in fishing lure technology.
Do fish like black lights?
Fish need aquarium lighting that’s designed to provide the natural lighting they would receive in the wild. Because black lights are ultraviolet, it’s only safe to use them in small doses. A black light in the 315 to 380 nm range is the least harmful.
Do fish hate UV light?

The fish retina has rod cells that provide high visual sensitivity in low light conditions and cone cells that provide higher temporal and spatial resolution than what rod cells are capable of.
Can Bass see UV light?
The bass retina contains only two types of color cones: a red and a green. They do not possess a blue cone, and certainly not a UV cone.Bass do not see UV light.
