What color do fish see?

How far can a fish see?

Standing next to one in a dense fog, you can make out every detail of its bark. „Fish live in perpetual fog, sometimes thin, sometimes thick. Our visual field can extend miles on a clear day, but in the clearest waterway, maximum visual distance is 100 to 150 feet and that’s rare.27.11.2017
