Living Glass Aquarium

A photorealistic living aquarium in your pocket — and on your TV.

Living Glass Aquarium is a fully simulated glass ecosystem: light bends through the water, caustics ripple across the sand, and every fish swims with its own body, behavior, and mood. Nothing is a video on iPhone and iPad — it's a living simulation, different every time you look.

BUILD YOUR TANK (iPhone & iPad) • 34 species — tetras and discus to tangs, clownfish, shrimp, and snails • Freshwater or saltwater; five substrates, backgrounds, and lighting moods • Plant it your way: swords, vals, mosses — or grow a pulsing coral reef • Six hand-stocked starter tanks, or roll a surprise • Compatibility warnings keep your stocking honest

WATCH IT LIVE • Feed the fish and watch them race • Day and night cycle — or follow your real clock; nocturnals wake at night • Tap a fish to meet it, name it, follow it around the tank • Cinematic camera and screensaver mode: a living ambient display • Procedural water soundscape, generated live — no loops

ON APPLE TV Six of the aquarium's tanks, rendered to seamless 4K ambient scenes — pick one or let them rotate. The calmest thing on your TV.

PRIVATE BY DESIGN No accounts, no ads, no analytics, no network access at all. Your tanks live on your device. The app collects nothing.

Living Glass Aquarium is a small, hand-crafted simulation — built to be watched the way you'd watch a real tank: slowly, and often.
