Common name: Bluelined wrasse

Scientific name: Stethojulis albovittata (Bonnaterre, 1788)

General information

The Bluebelly Wrasse, scientifically known as Stethojulis albovittata, is a vibrant and active fish that adds both color and dynamism to a saltwater aquarium. This species is known for its striking blue belly and the two distinct white stripes running along the length of its body, which make it a visually appealing addition to any tank.

In the wild, these wrasses are found in the Indo-Pacific region, often inhabiting coral-rich areas and clear lagoons. They are known for their interesting behavior and sexual dimorphism, where males exhibit more vivid coloration compared to females and juveniles.

Care

Bluebelly Wrasses are relatively hardy and can adapt to life in captivity if provided with the right conditions. They require a well-established tank with plenty of live rock for hiding and grazing. A sandy substrate is also beneficial as these wrasses may bury themselves in the sand when they feel threatened or during the night.

These active swimmers need ample space to roam, so a larger tank is recommended. They are not picky eaters and will accept a variety of foods including frozen, live, and flake foods. However, a diet rich in marine-based nutrients will help maintain their vibrant colors and overall health.

Reproduction

In the wild, Bluebelly Wrasses are protogynous hermaphrodites, meaning they are born female and have the ability to change to male later in life. This usually occurs when there is an absence of a dominant male in the group. In the aquarium, breeding these wrasses can be challenging due to their complex social structures and reproductive behaviors.

Habitat

Bluebelly Wrasses are commonly found in the tropical waters of the Indo-Pacific, from the Red Sea and East Africa to the central Pacific. They prefer shallow, clear waters with abundant coral growth, where they can be seen swimming actively during the day. In the aquarium, replicating their natural environment with live rock structures and a stable water quality is essential for their well-being.
