Yes, Scientists believe that fish can see colors, and their eyes work much like a human's. Some think that fish may see even more colors than humans.
It is possible that fish can see ultraviolet light much like insects, giving them the ability to see not only what humans see, but also things we can't.
Depending on the species of a fish, the eyes can be located close to the snout or further away from the snout. Both are normal, and can give you an indication of what some fish like to eat.

Most fish have color vision. The distance a fish can see underwater depends on water clarity. some fish can see 100 feet or more in very clear water, though a more likely range for lake dwelling fish is 10 to 20 feet.
Fish view the outside world through a window in the water surface. The diameter is about twice as wide as the fish is deep. In other words, a fish 5 feet deep would have a window 10 feet in diameter. Because the of the way light rays bend when they enter the water, fish can see objects above water that are far to the side of the window.
A fish's eye placement gives them a wide field of vision. They can see in all directions except straight down and straight back. Depth perception and 3-d vision is possible by looking directly ahead viewing the object with both eyes. Otherwise it only has 2-d vision since it is viewing an object with only one eye.
It was, as usual, a bright moonlit night on Easter Sunday night. Should not have been any surprise - the state of the moon is one factor that sets the date of Easter.
Something of a surprise was the fact that I was out fishing the river mouth at all. Usually I would buy into the generally held view that fishing for trout under a bright moon is pretty much a waste of time. But I had not been fishing for a week or two, and the mirror calm conditions were just too good to ignore.
Even more difficult to ignore was the fact that the rip was flowing almost parallel to the beach. Totally impossible to ignore was the fact that end of the rip was within casting distance. Sealing the decision was the complete lack of other fishermen in the rip – all at home I surmised cursing the bright moon and cloudless skies .
I rigged up my rod with a fast sinking shooting-head to a one-metre leader with a white Booby fly . At about 10pm I wandered down to the river mouth, walked the hundred metres, or so along the beach to the end of the rip, then waded out to mid-thigh depth.

Most of them yes! They don't have very good vision! That is why they need color in it! It enhances it!
