Common name: Rhomboid wrasse

General information

The Rhomboid Wrasse, scientifically known as Cirrhilabrus rhomboidalis, is a stunning and vibrant species popular among saltwater aquarium enthusiasts. This species is part of the Labridae family, which is known for its colorful and active members. The Rhomboid Wrasse is particularly noted for its shimmering purple to blue body and distinctive diamond-shaped tail, which gives it its common name.

Care

Rhomboid Wrasses are moderately easy to care for but do require a well-established aquarium with plenty of live rock for hiding and foraging. They are peaceful fish that can be kept with a variety of tank mates, but they should not be housed with aggressive species that may bully or stress them. A tightly fitting lid is essential as wrasses are known jumpers. They thrive on a varied diet of meaty foods, including frozen mysis shrimp, brine shrimp, and high-quality marine pellets.

Reproduction

In the wild, Rhomboid Wrasses are protogynous hermaphrodites, meaning they are born female and can change to male if the dominant male is no longer present. In the aquarium, breeding is rare, but environmental stability and a group consisting of one male and several females may encourage spawning behavior.

Habitat

Cirrhilabrus rhomboidalis is native to the Western Pacific, particularly around the Marshall Islands. They are typically found at depths ranging from 25 to 60 meters (82 to 197 feet) in coral-rich areas of lagoons and seaward reefs. Their natural habitat is characterized by clear waters and a robust reef structure that provides both food and shelter.
