My Little Aquarium: Fish Tank

You don't need a real tank to start an aquarium.

A school of neon tetras, graceful discus, koi in different patterns, tiny shrimp pottering along the bottom. 32 creatures swim in lifelike 3D.

■ World Aquarium (for shop and waiting-room screens) For hair and nail salons, clinic, dental and hospital waiting rooms, bank and city-office counters, libraries, hotel lobbies, cafés, care homes, and yoga or Pilates studios. Scenes from around the world change every few minutes, never repeating back to back. A small caption quietly shows each scene's region and fish names. No buttons appear, so you can leave it running in a shop or waiting room (the magnifier still works).

■ Winter scenes (new in version 1.1) "Snowy Koi Pond" with snow drifting onto the water, "Winter Goldfish" swimming slowly in low winter sunlight, and a "New Year Tank" with pine and red nandina berries. Together with the spring and autumn tanks, all four seasons are here.

■ View mode Choose from 37 moods such as "Calm Planted Tank", "Amazon Forest", "Japanese Goldfish Tank" and "Koi Tank", then just press PLAY. Sync with the real clock and the lights dim at night as the fish rest among the plants. Save up to three favorite settings with your own names.

■ Shop mode Choose any fish and any tank. Adjust temperature, pH, hardness, aeration and CO₂. If a combination doesn't work, the shop staff will kindly suggest a fix, like "Shall I set the heater to 25°C?" or "Which would you like?"

■ Magnifier Touch the tank to see that spot up close, like leaning in to peek at tiny fish and shrimp.

■ Show it on your TV Use AirPlay screen mirroring or an HDMI adapter to enjoy the aquarium on a big screen.
