Why are tropical fish colorful?
Reef fish have very distinctive colour patterns. Their bright colours are used for species recognition and protection. Fish use their bright colours for camouflage, blending in with the corals and plants of the reef habitat and they are able to ambush their prey and / or protect themselves against predators.
Furthermore, why do fish have different colors?
Fish come in lots of different colors and patterns. This coloration is very useful in a variety of ways. Color can camouflage (hide) a fish from both predators and prey. In open water, fish might be blue to match the background, while many fish in darker, deeper waters are black.
Secondly, why are freshwater fish less colorful? Fish camouflage would be based in part on the background colors of the environment. The lakes lack the corals. There is still plant life in the lakes, but generally using photosynthesis, and thus found in shades of green. Thus the background colors are far more drab, leading to more plain colored fish.
