The Bluehead Wrasse (Thalassoma bifasciatum) is a vibrant and active saltwater fish that brings constant movement and personality to any marine aquarium. As juveniles, these wrasses display a striking yellow body with bold blue markings on the head, making them a colorful addition to your aquarium.
Bluehead Wrasses are curious, intelligent swimmers that spend the day exploring rockwork in search of small crustaceans and other food. As they mature, their coloration changes dramatically, with adult males developing a brilliant blue head and green body—a fascinating transformation to watch over time.
These wrasses are hardy and adapt well to aquarium life when provided with plenty of swimming space, live rock for shelter, and a varied diet. A tightly fitting lid is recommended, as they are powerful jumpers.
