Colorful fish are often found in coral reefs and freshwater environments around the world. They come in various shapes, sizes, and colors, which help them adapt to their surroundings. Bright colors can serve as a warning to predators or help fish blend in with their habitat, such as coral or aquatic plants. Some popular examples of colorful fish include the clownfish, known for its orange and white stripes, and the betta fish, which displays vibrant hues and flowing fins. These fish are not only beautiful but also play important roles in their ecosystems, contributing to the balance of marine life.
