Care

Octopus vulgaris requires a species-specific tank setup with secure lids to prevent escape, as they are known to be quite the escape artists. The tank should have plenty of hiding places and a sandy substrate. They are carnivorous and thrive on a diet of live or frozen shrimp, crabs, and fish. It's important to note that they may prey on other tank inhabitants.

Reproduction

In captivity, breeding Octopus vulgaris can be challenging. After mating, the female lays clusters of eggs and tends to them until they hatch, after which she typically dies. The care of the larvae is complex, as they require small, live food and proper water conditions.

Symbiosis

While not known for symbiotic relationships like clownfish and anemones, Octopus vulgaris can interact with other species in interesting ways. For example, they have been observed using coconut shells and other objects as tools for shelter and protection.

Habitat

Octopus vulgaris is found in a variety of marine environments, from shallow waters to depths of over 100 meters. They prefer rocky areas, coral reefs, and seagrass beds. Their natural range is quite extensive, including the Mediterranean Sea, the Atlantic Ocean, and parts of the Indian and Pacific Oceans.
