Common name: Rusty blenny

General information

The Mediterranean Rainbow Wrasse, Parablennius sanguinolentus, is a colorful and active fish species commonly found in the Mediterranean Sea and the eastern Atlantic Ocean. This species is known for its vibrant coloration, which includes a mix of red, green, and blue hues, making it a visually appealing addition to any marine aquarium. They are relatively hardy and can adapt to life in captivity if provided with the right conditions.

Care

Mediterranean Rainbow Wrasses are generally hardy and can be a good choice for both beginner and experienced aquarists. They require an aquarium with plenty of live rock for hiding and foraging. These wrasses are known to jump, so a tightly fitting lid or screen is necessary to prevent escape. They are omnivorous and will accept a varied diet including frozen and live foods, as well as high-quality marine flake and pellet foods.

Reproduction

In the wild, Mediterranean Rainbow Wrasses are protogynous hermaphrodites, meaning they are born female and have the ability to 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 these fish can be challenging due to their complex social and environmental needs.

Habitat

The natural habitat of the Mediterranean Rainbow Wrasse includes rocky substrates and seagrass beds where they can be found at depths ranging from shallow waters to about 120 meters. They are often observed darting among the rocks and algae, searching for food. Their geographical distribution spans from the Mediterranean Sea to the coastal waters of the eastern Atlantic, from Portugal to Angola, including the Canary Islands and Cape Verde.
