Pixel Aquarium turns your AWTRIX NG into a tiny living underwater world. Colorful fish swim at different speeds and depths, occasionally leaving the screen as new species arrive. Bubbles rise from the plants and treasure chest, while rocks and sand create a cozy aquarium scene. Press the select button to drop food and watch the fish react. At night, the aquarium dims and the fish slow down. A relaxing little companion for your desk, with no goals or pressure.
