Common name: Sixbar wrasse

General information

The Sixbar Wrasse, Thalassoma hardwicke, is a vibrant and active fish that adds both color and dynamism to a saltwater aquarium. Known for its striking pattern of six horizontal bars on a greenish-blue body, it is a popular choice among aquarists. Juveniles and females exhibit a different coloration compared to males, which develop brighter colors and a more pronounced lunate tail as they mature.

Care

Sixbar Wrasses are known for their hardiness and adaptability to aquarium life. They require a well-established tank with plenty of live rock for hiding and hunting small invertebrates. A tightly fitting lid is essential as these wrasses are known jumpers. They thrive in a varied diet of meaty foods, including frozen mysis shrimp, brine shrimp, and quality marine flake and pellet foods.

Reproduction

In the wild, Thalassoma hardwicke exhibits protogynous hermaphroditism, where individuals start life as females and can change to males. In the aquarium, breeding is rare, but environmental stability and a well-matched pair can encourage spawning behavior.

Habitat

The Sixbar Wrasse is commonly found in the Indo-Pacific region, from the Red Sea to South Africa and east to the Line Islands. They inhabit coral-rich areas and lagoons, often seen at depths ranging from shallow waters to about 20 meters. Their natural environment should be mimicked in the home aquarium to ensure their well-being.
