We are on a rocky wall around 36/39 meters deep with steps that go up to 42 meters, this is one of the ideal habitats of Anthias anthias, the Swallowtail sea perch or Marine goldfish. This small fish belonging to the Serranidae grouper family is one of the most common and easy to find species at depths around 40 meters and which colors the seabed of the Mediterranean Sea with a beauty comparable to that of coral reefs. In fact, even the Mediterranean Sea has its coral reefs and as you can see from the movie, once the dark rock wall is illuminated, it transforms into a landscape of a thousand colors thanks to corals, sponges and its fish, including Anthias anthias.
