This video, from the USA, says about itself:
Dive into the Academy’s Philippine Coral Reef tank— one of the deepest exhibits of live corals in the world. This impressive tank houses a broad range of aquatic life from the coral reefs and mangroves of the Philippines, a global biodiversity hotspot and an important location for scientific research. Tune in daily at 11:30 am and 2:30 pm PST to watch and listen as Academy divers feed the creatures in the Philippine Coral Reef exhibit and answer visitor questions.
The California Academy of Sciences is the only place in the world with an aquarium, planetarium, natural history museum, and 4-story rainforest all under one roof.
