In December 2025, Luc spent two weeks in the Lembeh Strait, exploring its volcanic seabed to document the underwater microcosm. During a dusk dive, he focused on the elusive mandarinfish, a species renowned for its extraordinary and fleeting twilight mating ritual. These small, vividly coloured fish emerge from the coral in pairs, briefly rising into the water column to complete reproduction, before vanishing in a fraction of a second. After countless attempts and patient waiting, Luc managed to capture the exact moment of the nuptial ascent, immortalizing the chromatic harmony and fragility of this brief instant.
