Appquarium - Living Aquarium

A living aquarium for any screen.

Got an old phone in a drawer? A spare tablet? A TV with Chromecast? Appquarium turns any screen into a calm, living ocean. Set it on your desk. Cast it to your living room. Let it run on your nightstand. The ocean fills your space, 24/7.

This isn't a game. It's digital decor — alive.

📺 ANY SCREEN BECOMES AN AQUARIUM
• Old Android phone → ambient display, plugged in, always on
• Spare tablet → fish tank for the kitchen, the desk, the kids' room
• TV via Chromecast → 65-inch living aquarium in your living room
• Phone on your nightstand → calming screen before sleep

🐟 24+ FISH SPECIES, EACH ALIVE
Banggai cardinalfish, moorish idols, mandarinfish, ocean sunfish. Each fish has its own personality — exploring, sleeping, feeding, reacting to your taps. No robotic loops. Every fish lives at its own rhythm.
