Royal Gramma Basslet in Deep Reef Cavern Shade

Full prompt

High-contrast underwater macro photograph of a Royal Gramma basslet hovering under a limestone reef ledge, adapted into a panoramic 16:9 horizontal gallery print composition. The fish swims inverted in the left foreground, displaying its dramatic two-tone coloration with saturated electric violet-magenta across its head and forebody transitioning sharply into bright sunshine-yellow along its rear and tail. Subtle off-camera strobe light illuminates the fish and tiny red encrusting sponges and delicate white tube worms sprouting from the limestone overhang. The scene stretches horizontally across the right into deep indigo and teal cavern shadows, creating cinematic negative space that accentuates the vibrant jewel-like glow of this secretive tropical species.
