Is this aquarium a prerecorded fish video?
No. The aquarium is a live procedural scene rendered in your browser. Fish vary their direction, depth, speed and pause timing, with foreground and background scales that create a sense of layered water rather than one repeating screensaver loop.
How the movement works
Fish alternate among cruising, pausing and darting. Different depth values change scale and opacity; small bubbles rise independently, and touch reactions push nearby fish away from the paw.
