The Black-Backed Wrasse (Anampses neoguinaicus), also known as the Black Pearl Tamarin Wrasse, is endemic to the reefs of the Indo-Pacific, including Fiji, Australia, and Indonesia. Females and juveniles typically have a pearl-white stomach and midsection with a solid black dorsal section, all of which is covered by small blue spots. Terminal-phase males, however, typically have less pronounced black on their backs, and adorn maroon and blue designs above their eyes and on their fins. They reach a maximum size of 9 inches and should be housed with fish of similar size and temperament. Their diet should consist of vitamin enhanced mysis, krill or other crustaceans. With that being said, they should not be kept with smaller, prized crustaceans.

Black-Backed Wrasse Habitat

Originating from the tropical waters of the Indo-Pacific region, the Black-Backed Wrasse is commonly found inhabiting coral reefs, lagoons, and rocky areas with abundant hiding spots and moderate to strong water currents.

Black-Backed Wrasse Reef Compatibility

While considered reef safe, caution should be exercised when keeping them in reef tanks with small crustaceans and ornamental shrimp as they may prey on them.
