The LEGO Icons Tropical Aquarium (Set #10366) is a stunning 4,154-piece display model designed for adults, recreating a vibrant, fully inhabited tropical fish tank in meticulous brick-built detail. Measuring over 20.5 inches (52 cm) wide, it makes a striking centerpiece for a living room, home office, or any space that could use a touch of underwater wonder — no water changes or fish feeding required.

The set features multiple interactive mechanisms hidden throughout the build. A rotating "stone" element reveals a sea crab creeping out from its hiding spot. A grey knob causes a cluster of sea anemones to swirl as though caught in a current. A rear-mounted crank opens and closes a decorative treasure chest resting on the tank floor. A side crank makes a striped brickfish wiggle and "swim" through the water. These kinetic surprises make the finished model feel alive and engaging even on display.

The aquarium is populated with an imaginative cast of brick-built fish and sea life, including a rainbowfish, two color variants of angelfish (yellow-orange and purple), a special LEGO-original striped brickfish, colorful water plants, coral formations, and sea anemones. The overall color palette is one of the most vivid ever used in a LEGO set, showcasing the full breadth of the LEGO color library in one cohesive build.

Designed as part of the LEGO Icons adults-welcome lineup, this set is intended as a meditative building experience as well as a permanent display piece. It is exclusive to LEGO.com and LEGO Stores.
