Blue Head Wrasse BHW080602 WYSIWYG Size: L 4.5"

Thalassoma bifasciatus

The Blue Head Wrasse is a vibrant and active reef fish prized for its striking coloration and engaging personality. Males display brilliant blue heads that transition to yellow and orange bodies, while females show more subdued green and yellow tones. This wrasse reaches approximately 4.5 inches at maturity and thrives in established reef aquariums with plenty of live rock for hiding and foraging. Known for their curious and sometimes aggressive behavior, Blue Head Wrasses are best kept singly or in pairs within larger systems. They feed on small crustaceans, mollusks, and prepared foods, making them excellent for controlling unwanted pests like bristleworms and small snails. Provide strong water flow, stable temperatures between 72-78°F, and a varied diet to maintain their vibrant coloring and optimal health. A hardy and rewarding addition to intermediate to advanced reef keepers.
