The bigger it is, the more people believe it. LEGO today unveils a new lifestyle product to proudly display in the living room: the LEGO ICONS 10366 Tropical Aquarium set with its inventory of 4154 pieces and its retail price of €449,99.
Those who cannot be satisfied with the contents of the LEGO Creator 31122 Fish Tank set (352 pieces - €29.99) released in June 2021 and withdrawn from shelves at the end of 2022, will therefore have at hand from November 13, 2025 in Insiders preview enough to assemble an aquarium 52 cm long by 36 cm high, populated with four fish, a crab, an oyster, sea snails and filled with aquatic vegetation and corals.
The construction does not include glazing on the three sides that allow access to the constructions placed inside the frame. The elements integrated into this aquatic diorama seem rather successful to me, but I find the blue background a little ridiculous and sloppy. It's up to you, as far as I'm concerned I can't imagine for a second spending €450 on this somewhat kitsch and overpriced thing.
