Aquarium Fishes 2026 24-Day Advent Calendar

Aquarium fishes advent box with tropical fish, plants, bubbles and driftwood

The Aquarium Fishes 2026 24-Day Advent Calendar is a December countdown for fishkeepers. The box is a little underwater world: tropical fish, swaying plants, bubbles and driftwood, all in clear water with a dusting of snow at the edges. Every one of the 24 windows opens on a small acrylic fish, so the tank on the box slowly fills your tree.

No food, no live animals, nothing to feed. Just a fish a day until Christmas Eve.

Tropical Fish and Driftwood on the Aquarium Box

The front is a blue calendar box set inside a busy aquarium scene. Bright tropical fish swim past green plants, bubbles rise from below, and a piece of driftwood runs along the bottom. Snowy accents on top tie it back to the season. The title is in large cream lettering, a red ribbon banner crosses the front, and a wooden-style plaque reads "24 Acrylic Ornaments."

Fishes Behind Each Advent Window

Each window is die-cut, so a thumb opens it along the dotted line. Inside, a molded plastic tray holds one flat acrylic (mica) fish per day, about 1.3 x 1.3 in (3.2 x 3.2 cm). The fishes come in orange, blue, yellow, red, black and white patterns, the kind of colors you see in a well-stocked freshwater tank. Both faces are printed, one matte and one glossy, and one face has a protective film to peel off first. A perforated tab at the top is for hanging.

Why Fishkeepers Like an Aquarium Calendar

Anyone who keeps a tank knows the routine: check the water, feed the fish, watch them for a minute longer than planned. A daily window fits that habit. The calendar can sit right next to the tank, and the day's fish can hang on a small tree beside it, so the real aquarium and the acrylic one share a shelf for the month. An advent calendar full of fishes also gets kids counting the days without a sugar rush.

It also suits people who love the ocean but cannot keep a tank: kids who know every fish at the public aquarium, divers, snorkelers, and anyone who would rather decorate with blue and green than red and green.

Hanging Acrylic Fishes on a Christmas Tree

The pieces are light and flat. Thread a thin ribbon, a fishing-line loop or an ornament hook through each tab; hangers are not included. They look good on a white or silver tree with blue lights, along a garland over a window, or clipped to a driftwood branch in a vase. Turn the glossy side out where light hits it, and the colors read like fish catching the light in clear water.
