Fish come in a wide variety of colors, which can serve different purposes. Bright colors, like those seen in clownfish or parrotfish, often help attract mates or warn predators of their toxicity. In contrast, some fish, such as flounder, have muted colors that allow them to blend into their surroundings, providing camouflage from predators. The colors of fish can also change based on their environment or mood. For example, betta fish can display vibrant colors when they are excited or during mating displays. Additionally, some species can change color to communicate with others or adapt to different habitats, showcasing the diversity of fish coloration in aquatic ecosystems.
