Golden Lavender Giant Clam (Tridacna sp.) - RW2 Large

The Golden Lavender Giant Clam is a spectacular giant clam displaying a soft lavender to pink mantle with intricate dark purple spotting and a luminous blue-violet central area. The combination of golden-lavender tones, dense leopard-like markings, and intense fluorescence under blue reef lighting makes this a highly distinctive centerpiece for a reef aquarium. The clam extends its mantle beyond the shell to maximize light exposure and should be provided with a stable attachment point.
