The yellow tang is a popular marine fish known for its vibrant yellow color and distinctive oval shape. Native to the coral reefs of the Pacific Ocean, particularly around the Hawaiian Islands, it thrives in warm, shallow waters. This species is a herbivore, primarily feeding on algae, which helps maintain the health of coral reefs. Yellow tangs are often kept in home aquariums due to their striking appearance and relatively peaceful nature. They can grow up to 8 inches in length and are recognized for their bright yellow bodies and a small, sharp spine near the tail, which they use for defense against predators.
