Are fish sensitive to red light?

Detailed analyses using medaka, goldfish, zebrafish, guppy, stickleback and cichlid revealed that all the fish were sensitive to light at a wavelength greater than or equal to 750 nm, where the threshold wavelengths varied from 750 to 880 nm. Fish opsin repertoire affected the perception of red light.

Can fish see in dark?

Fish living in the deep sea manage to navigate in complete darkness. It’s not strictly ‘seeing’ but fish have rows of pressure-sensitive organs running down each side of their body called the lateral line, which allows them to sense nearby animals from the pressure changes in the water.

Do fish see forward or sideways?

Unlike humans, many fish have their eyes set far apart on the sides of the head rather than to the front. This allows a very wide arc of monocular side vision for spotting predators or prey, but provides only a narrow range of overlapping binocular vision to the front.
