clubfish

Clubfish refers to a group of marine fish belonging to the family Clubidae. These fish are characterized by their somewhat elongated bodies and the presence of a prominent, somewhat club-shaped dorsal fin in many species. They are typically found in tropical and subtropical waters, inhabiting coral reefs, rocky outcrops, and seagrass beds. Clubfish are generally small to medium-sized, with most species measuring less than 20 centimeters in length.

The diet of clubfish varies depending on the species, but many are omnivores, feeding on algae, small invertebrates, and plankton. They play a role in the reef ecosystem as both grazers and prey for larger fish. While not a commercially significant group, some clubfish species are kept in aquariums due to their vibrant colors and interesting behaviors. Identification of specific clubfish species can be challenging due to their diversity and often similar appearances. Further research is ongoing to better understand the taxonomy and ecological roles of various clubfish.
