About this tool
Digital Aquarium is a free online zen & relaxation tool. Goldfish tank fountain stream pure CSS animation waterscape. Calm your mind with soothing visuals and sounds. It runs entirely in your browser — no download or sign-up needed.
The virtual aquarium simulates a complete tropical fish tank environment. Multiple colorful tropical fish swim freely in the fish tank, and each fish has a unique swimming trajectory and behavioral pattern. There are swaying water weeds at the bottom of the fish tank, the background is a gradual seawater color, and bubbles rise from the bottom from time to time.
You can choose different types of fish (clownfish, angelfish, guppy, etc.) and adjust the number of fish, swimming speed, and lighting effect. Supports full-screen display and is suitable as a desktop background or relaxation tool. Fish swim using a natural Bezier curve path to avoid mechanical feeling.
Use Canvas to draw all elements, fish use sprite animation to achieve swimming effects, water plants use sine waves to simulate swaying, and bubbles use particle systems to simulate rising. The overall rendering uses a translucent effect to create a sense of underwater light and shadow. This is a purely visual relaxation tool with no interactive goals.
The virtual aquarium displays a fish tank full of tropical fish on the screen. The fish swim freely, the water plants sway, and bubbles rise, creating a peaceful underwater world.
