Introduction

The axillary wrasse is a small wrasse that inhabits rocky areas and seagrass beds along the Mediterranean coasts. It is also found from the temperate waters of the Atlantic coast to the Azores. The males are among the most colorful fish in these habitats.

How to recognize the axillary wrasse ?

Together with the ocellated wrasse, it is one of the most colorful fish in the Mediterranean. The body is elongated, similar to the ocellated wrasse. The color can vary depending on the substrate and stress levels.

It is easily distinguished by its color pattern and yellow eye. It differs from the ocellated wrasse by the absence of a greenish spot near the operculum. The upper flank is beige, while the lower part is lighter. Some individuals take on an orange-yellow hue.

Sexual dimorphism

Males grow faster than females and are larger in size.

Behaviour & Life cycle

  • diet
    omnivorous with carnivorous tendency
  • Sociability
    living as a couple or alone
  • territorial
    Yes
  • Way of living
    diurnal

Like most wrasses, juveniles inhabit shallow waters in seagrass beds and rocky areas, often in the company of similar species.

Adults are encountered in pairs in seagrass beds. These fish are quite shy and more difficult to observe compared to the peacock wrasse or the rainbow wrasse.

Males are territorial during the breeding season. Dominant females and males may live in scattered groups. Their diet typically includes mollusks, gastropods, bivalves, tube worms, chitons, sea urchins, and bryozoans.

Reproduction

  • Reproduction

  • Hermaphrodite
    protogynous

Reproduction takes place from spring to early summer. The dominant male prepares an algae nest in the shape of a cup.

Once the nest is constructed, he attracts one or more females through courtship displays. After spawning, the male fertilizes the eggs and starts to protect his offspring. The female does not stay after spawning and shows no concern for the eggs.

During this period, males are particularly aggressive towards other males of the same species. Intimidation displays and fights are common. It is possible that "satellite males", pretending to be females, participate in fertilization by releasing quick ejaculations over the nest, but this behavior needs further confirmation.

Harmless species

This species does not represent any particular threats to humans when encountered in its natural environment.

Geographic distribution & Conservation

The axillary wrasse is mainly found in the Mediterranean Sea and the Black Sea, but it can also be encountered along the Atlantic coasts. It is also present in the Azores and the Moroccan coasts. It has a wider distribution than its Mediterranean cousins and generally inhabits the same regions as the peacock wrasse.

Fishkeeping

Not recommended

We do not recommend keeping this species in an aquarium. It has unpredictable needs which, if not met, generate significant stress, potentially leading to a shorter life expectancy, an interruption of its growth or the development of pathogens.
