Red-Lined Wrasse – A Striking Addition to Your Reef Aquarium
Bold, beautiful, and brimming with personality, the elegantly-striped Red-Lined Wrasse makes the perfect addition to showcase in your display reef aquarium. Also known in the hobby as the False-eyed or Biocellate Wrasse, juvenile Halichoeres biocellatus and sub adults are easily identifiable by a pair of ocelli, or “false eyes”, on the dorsal fin which disappear as the Red-Lined Wrasse matures.
The ideal setup for the Red-Lined Wrasse will be a well-established saltwater aquarium of at least 50 gallons in size with a tight-fitting lid. Aquascape liberally with live rock, making sure to include a large area of open substrate to best replicate the seaward reefs from which the Red-Lined Wrasse originates. In the wild, the Red-Lined Wrasse also prefers to inhabit reef crest areas.

The Red-Lined Wrasse has been a stunning centerpiece in my 75-gallon reef tank. The coloration is vibrant and the fish is very active. I noticed the false eyes in the juvenile stage, which was fascinating. It’s a great choice for a visually appealing species that doesn’t stress easily.

I’ve had this wrasse for six months now and it’s thriving. The tank setup includes live rock and open sand, which matches its natural habitat. The false eyes were visible when it was young, and it has since matured. It’s a beautiful fish that adds a lot of movement to the tank.
