The LEGO Creator 3-in-1 Fish Tank (31122-1) creates an underwater display using 352 pieces. The tank holds five fish: a clown fish, a regal blue tang, a yellow tang, a cardinal fish, and an anthias fish. A mini submarine, coral, and an aquatic plant populate the scene. Curved slope elements form the fish bodies. This Creator 3-in-1 model rebuilds into two alternate designs: an artist's easel or a treasure chest. The set provides adaptable display options for any collector.
