As the sun sets on Tropical North Queensland's mountain ranges, steamy rainforests and shallow reef lagoons stir with life. Reptiles, amphibians, insects, and nocturnal fish sense the onset of dusk and emerge from their daytime lairs. Brightly coloured reef fish seek shelter in coral caves as predatory nocturnal sharks, rays, and grouper awaken. ‘Aquarium by Twilight' takes you on an exclusive two hour guided tour to witness this remarkable transition as day slides into sunset.
