What colors do fish see best?

Fish can see a wider range of colors than humans, including ultraviolet and infrared light. However, fish do not see well in very dim light or very bright light.

The best colors for fish to see are green and red. Green light penetrates water well, and fish can see it even in relatively deep water. Red light is also visible to fish, but it does not penetrate water as well as green light.

Other colors that fish can see include blue, yellow, and orange. However, these colors are not as visible to fish as green and red.

The ability of fish to see certain colors is important for a number of reasons. For example, fish use their vision to find food, avoid predators, and communicate with each other.
