Guide to the RCH


  • Our two-storey reef aquarium is visible from Emergency on Lower Ground (Underwater) and Main Street on Ground floor (Beach).

    It is home to approximately 40 different species of fish, two black tip reef sharks and one epaulette shark. All species can be found on the Great Barrier Reef, Australia. The biggest fish is a hump head Maori Wrasse whose name is 'Humpy'.

    The aquarium is managed by Advanced Aquarium Technologies as part of the hospital's community partnership program.

    The fish are fed twice a day, and the sharks are fed every two days. Their diet consists of foods such as whiting, squid, bonito, tailor, prawns, sardines, pilchards, pipis, mysis shrimp, brine shrimp, nori and wombok.

    The tank is cleaned daily. Divers wipe algae from the acrylic walls with a cloth, vacuum dirt from the gravel on the bottom of the tank and scrub algae off the coral.

    The tank is 7.5 metres deep, four metres in diameter and holds 153,000 litres of salt water (including filtration system). The walls are eight centimetres thick and the water temperature is 25.5 to 26 degrees Celsius.
