Site details

Named for its dense, colourful concentration of fish, The Aquarium on the western side of Lighthouse Reef Atoll has a shallow coral garden that rolls over a 15-18m wall draped in sponges and sea fans. Current is usually present over the reef top but eases along the wall, making it an easy, photogenic dive. It is a popular second or third dive on Blue Hole day trips.
