visual protection from predators
. As an example, we can take two different habitats: Caribbean and West Coast reefs.

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.
Why some are fish colorful and others are not?
The clear water of coral reefs enhances visual perception, while the structural complexity creates solid, physical barriers that conspicuously coloured fishes use as protection from predators
.
Why are salt water fish colorful?
He suggested that fish are conspicuously colored
to help them identify their own species in the crowded reef environment

Why are saltwater fish prettier than freshwater fish?
Saltwater fish have a different environment from freshwater fish, so they have different colors to camouflage
. Most colorful saltwater fish live on coral reefs, which have a vivid array of colors.
Why are so many reef fish blue and yellow?
In the blue waters of the reef, the colors yel- low and blue travel the farthest

Are parrotfish herbivores?
Queen parrotfish are herbivores
that graze the reef, using their beaks to scrape plants and algae from the reef surface. Oftentimes, this habit involves ingesting corals and other animals as well, but they are primarily herbivorous. Through their feeding strategies, parrotfishes create much of the sand around a reef.
