New LEGO ICONS 2025: the 10366 Tropical Aquarium set is online in the Shop

Bigger is better. LEGO today unveils a new lifestyle product to proudly display in the living room: the LEGO ICONS set. 10366 Tropical Aquarium with its inventory of 4154 pieces and its public price of €449,99.

Those who cannot be satisfied with the contents of the LEGO Creator set 31122 Fishtank (352 pieces - €29.99) released in June 2021 and removed from shelves at the end of 2022, will therefore have on hand from November 13, 2025, as a preview, Insiders will have what it takes to assemble an aquarium 52 cm long and 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.
