What is a "wrasse"?

A wrasse is a small to medium-sized marine fish found in coastal waters worldwide. They are known for their vibrant colors and striking patterns, making them popular among aquarium enthusiasts. Wrasse have elongated bodies, typically with thick lips and sharp teeth, which they use to feed on a variety of prey, including small invertebrates and crustaceans. They are often found in rocky or coral reef habitats, where they display a range of behaviors, such as cleaning other fish and changing their gender during their lifetime. Wrasse plays an important role in marine ecosystems by contributing to reef health and maintaining ecological balance. Due to their unique characteristics and wide distribution, wrasse species have captivated the interest of both researchers and nature enthusiasts alike.
