Ocellated Wrasse

Symphodus ocellatus

The Ocellated Wrasse is the Mediterranean's most diligent architect, famous for building complex algae nests. Its striking 'eye-spot' and vibrant personality make it a favorite for coastal underwater explorers.

Behavior

The Ocellated Wrasse is one of the most socially complex small fish you can observe in Mediterranean waters. Unlike many other small reef fish, they exhibit fascinating breeding behaviors centered around nest-building. Dominant males spend significant energy harvesting various species of algae to construct elaborate mounds where females lay their eggs. This 'architectural' phase is a highlight for anyone watching via an underwater camera, as the males are tireless in their pursuit of the perfect piece of seaweed.

Beyond their construction skills, their social hierarchy is intriguing. In any given population, you might find three types of males: the large territorial males who build and guard nests, 'satellite' males who help defend the nest in exchange for a chance to spawn, and 'sneaker' males who mimic females to get close to the eggs. They are generally peaceful but can be quite territorial around their nests, darting at intruders to protect their future brood.

Camera Tips

To capture the Ocellated Wrasse on an underwater 'backyard' camera, placement is everything. Look for rocky outcrops that transition into seagrass beds at a depth of about 1 to 3 meters. If you spot a small mound of multi-colored algae that looks 'placed' rather than grown, you've found a nest. Position your camera about 50 cm (20 inches) from this mound, angled slightly upward to catch the light. Using a weighted tripod or a suction mount on a flat rock is essential to prevent the camera from shifting with the tide or surge.

Because these fish are highly visual, lighting is your best friend. Choose a day with clear water and high sun to bring out the iridescent blues and oranges on the male’s gill covers. If you are filming in an area with a lot of particulate matter, a red filter can help restore the color balance that is lost even in shallow water. For the most natural behavior, leave the camera stationary for at least 30 minutes; the wrasse will eventually ignore the device and return to its busy schedule of nest maintenance and courtship.

If you want to draw them in for a close-up, a 'lure' of crushed mussel or sea urchin tucked into a rock crevice near the lens works wonders. However, avoid overfeeding, as this can attract larger predators like sea bass that might scare the wrasse away. Set your camera to a high frame rate (at least 60fps) because these fish move in quick, jerky bursts—slowing down the footage later will reveal the intricate 'shiver' dance the males perform to attract females.

Frequently Asked Questions

Ocellated Wrasse are strictly diurnal, meaning they are active during the day. They are most visible during the middle of the day (10 AM to 4 PM) when the sun is high, providing the light they need to forage and find colorful algae for their nests.

The best way to attract them is to place your camera near a known nesting site or a patch of algae-rich rock. You can also use a small amount of crushed shellfish as a lure, which will encourage them to forage directly in front of your lens.

Their diet consists mostly of small invertebrates. They spend their days picking through seaweed and rocky crevices for tiny crabs, shrimps, and worms.

Yes, they are very common in the shallows! They are frequently found at depths between 1 and 5 meters, making them easy to spot while snorkeling or using a shallow-water camera rig near the shore.

The key is the 'ocellus' or eye-spot on the gill cover. Look for an orange or red spot outlined in bright blue. While other wrasses have spots, the specific color and location on the operculum (gill cover) are unique to this species.
