Common name: Ornate wrasse

General information

The Ornate Wrasse, scientifically known as Thalassoma pavo, is a vibrant and active fish that adds both color and dynamism to a saltwater aquarium. It is known for its striking green, blue, and orange patterns, which can vary significantly between individuals. This species is part of the Labridae family, which is known for its members' cleaning behaviors and their role in controlling pest populations in the reef.

Care

Ornate Wrasses are hardy and adaptable, making them suitable for both beginner and experienced aquarists. They require a well-established tank with plenty of live rock for hiding and hunting. A sandy substrate is also beneficial, as these wrasses may bury themselves in the sand when they feel threatened or during the night. They are known to jump, so a tight-fitting lid is essential to prevent escape.

Their diet should include a variety of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood. They are also known to eat small invertebrates and may help control populations of bristle worms and other pests.

Reproduction

In the wild, Ornate Wrasses are protogynous hermaphrodites, meaning they are born female and can change to male later in life. This change is often triggered by social cues or the absence of a dominant male. In the aquarium, breeding is less common, but environmental stability and a well-matched pair can encourage spawning behavior.

Habitat

Thalassoma pavo is native to the Mediterranean Sea and the eastern Atlantic Ocean, from the coast of Portugal to Angola, including the Azores and Canary Islands. They are typically found in shallow, rocky coastal areas and seagrass beds, where they swim openly in search of food.
