$47.55

The Half & Half Wrasse (Hemigymnus melapterus), also known as the Blackedge Thicklip or Banner Wrasse, is a striking marine species recognized for its dramatic bicolored pattern in its juvenile stage and impressive size. As it matures, it develops deep green tones highlighted by distinctive pink and blue markings along its prominent thick lips and head.

Originating from the Indo-Pacific, this active carnivore thrives in large fish-only systems with a deep, fine-sand substrate for burrowing and foraging. Its natural sand-sifting behavior and robust build make it an engaging centerpiece for experienced marine aquarists maintaining substantial setups.
