Every day of the year, the team working at the Aquarium de la Réunion must ensure all the animals remain healthy. Biologists and diver-keepers focus on keeping the tanks in top condition. They also welcome new residents to the quarantine tanks, and study and monitor reproduction. Finally, they maintain the technical installations (pumps, filtration, ventilation, lighting, etc.). Holding 600,000 litres of seawater, the tanks are maintained around the clock.
