A clownfish is a type of marine fish belonging to the subfamily Amphiprioninae in the family Pomacentridae. These colorful fish are notable for their vibrant orange and white stripes, which help them stand out in their natural habitat of coral reefs. Clownfish are mutualistic with sea anemones, as they seek shelter within their tentacles while providing the anemones with nutrients from their waste. This symbiotic relationship protects clownfish from predators and enhances the health of the anemones. Clownfish are popular in home aquariums due to their striking appearance and interesting behaviors, especially their unique interactions with anemones.
