LEGO Icons 5009823 Fish Tank Filter & Fish Food GWP Officially Revealed | 13th November 2025

The latest LEGO Icons display model of 10366 Tropical Aquarium has just been officially revealed to go alongside the striking 4,154-piece display model is its corresponding, exclusive Gift With Purchase. This GWP in particular is 5009823 Fish Tank Filter & Fish Food, which will only be available with purchases of the 18+ $479.99 / €449.99 / £399.99 fish tank from the 13th to the 19th of November 2025.

Similar to last month's 5009609 Captain Jack Sparrow’s Compass, 5009823 is another yellow box promotional item and therefore will likely only be available for those few days in November before never returning again. The build itself isn't that substantial either, recreating a miniature fish tank filter that will sit outside of the 4,154-piece aquarium.

The Fish Tank filter includes a simple, blocky filter body, probably in black, with plenty of translucent blue elements replicating water inside the filter. The filter also includes a small brick-built fish, possibly a small reference to Finding Nemo. A small intake pipe extends from the filter toward the tank, which is fully compatible with and can be easily attached to 10366. Finally, the 177-piece build includes a small box of fish food with a printed red fish on it.
