Common name: Sunset wrasse

General information

The Sunset Wrasse, scientifically known as Thalassoma grammaticum, is a vibrant and active fish that adds both color and dynamism to a saltwater aquarium. It is part of the Labridae family, which is known for the cleaning behavior exhibited by many of its members. This species is distinguished by its striking coloration, which includes a mix of blue, green, and yellow hues, with males typically displaying more intense colors than females.

Care

Sunset Wrasses are relatively hardy and adaptable, making them suitable for both intermediate and experienced aquarists. They require a well-established aquarium with plenty of swimming space and rockwork to provide hiding places. A sandy substrate is also beneficial as they may bury themselves in the sand when sleeping or feeling threatened. A varied diet of meaty foods, such as mysis shrimp, brine shrimp, and finely chopped seafood, will help maintain their health and coloration.

Reproduction

In the wild, Thalassoma grammaticum exhibits protogynous hermaphroditism, where individuals start life as females and can change to males as they mature. In the aquarium, breeding is less common, but with a stable environment and a group consisting of multiple females and a dominant male, spawning may occur.

Habitat

Sunset Wrasses are found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They inhabit coral reefs and rocky outcrops, often at depths ranging from shallow waters to about 30 meters. They are active swimmers and can often be seen darting among the corals in search of food.
