The outer skin of the fish is a cladding of ceramic tiles decorated with texts and images relating to the history of Belfast. According to the Belfast City Council, each scale "tells a story about the city". Material from Tudor times to present day newspaper headlines are included along with contributions from Belfast school children. The Ulster Museum provided the primary source of historic images, while local schools/day centres located along the line of the River Farset were approached to provide drawings for the fish. Images were provided by Glenwood Primary School, St Comgalls and Everton Day Centres.
The Big Fish contains a time capsule storing information, images, and poetry on the City.
