Surgeonfish are colorful marine fish belonging to the family Acanthuridae. They are commonly found in warm, tropical waters, particularly around coral reefs. These fish are known for their distinctive body shapes and vibrant colors, which can include shades of blue, yellow, and orange. Surgeonfish have a unique feature: sharp spines on either side of their tails, which they can use for defense against predators. These fish primarily feed on algae, grazing on it from rocks and coral surfaces. Surgeonfish play an important role in maintaining the health of coral reefs by controlling algae growth. Popular species include the palette surgeonfish and the yellow tang, both of which are often seen in aquariums.
