Care
Keeping a Mediterranean Moray in a home aquarium requires a large tank with plenty of hiding places to mimic its natural environment. They are carnivorous and should be fed a varied diet of meaty foods such as fish, squid, and crustaceans. Caution is advised when handling these eels, as they can deliver a powerful bite if threatened.
Reproduction
Little is known about the reproductive habits of the Mediterranean Moray in the wild. In captivity, breeding these eels is extremely rare and not well-documented. They are oviparous, with females releasing eggs that are fertilized externally by the male.
Habitat
The Mediterranean Moray typically resides in shallow waters, often found at depths ranging from the shoreline to around 80 meters. They prefer rocky substrates and can be found in coastal lagoons and rocky reefs, where they spend most of their time concealed within the reef structure.
