This tank contains spectacular coral and gorgonian (soft coral) species that are typical of the Eastern Atlantic. The aquarium is bathed in blue light to recreate the marine depths these animals inhabit. The space is mostly inhabited by invertebrates and it is one of the aquarium's most distinctive. Its color has led some experts to call it the jewel of the Aquarium.
Among the species in this tank there are the candelabra gorgonian (Ellisella paraplexauroides), orange tree coral (Dendrophyllia ramea), and sea fan gorgonian (Lophogorgia lusitanica). These living things are often confused with plants but they are actually animals that live in colonies made up of hundreds of polyps. Swimming among them are fish like the damselfish (Chromis chromis) and the swallowtail sea perch (Anthias antias).
