Throw fish. The shark hunts.
The prey fights back.
Pet Shark isn't a pre-rendered loop. It's a live 3D simulation where predator and prey each make their own decisions.
Throw
Double-tap anywhere in the app or on your home screen wallpaper to toss live fish into the depths. Watch the ripple, hear the splash, and set the hunt in motion.
Physics buoyancy, instant predator alertStalk
The Great White weighs distance, water disturbance and prey trajectory. It cruises in from beneath, angles for a blind-spot pursuit, then bursts forward to snap its jaws shut.
Intercept vectors, burst-speed lungesStrike or escape
Swift mackerel burst-dash from danger, smarter species weave behind corals, and whole schools flock together to confuse the shark.

Questions, answered
What is Pet Shark?
Pet Shark is a free 3D live wallpaper and animated shark aquarium for Android. A photorealistic Great White Shark swims over a coral reef, and you can throw fish into the water and watch it hunt them in real time.
How does the fish throwing and AI hunting work?
Double-tap to throw bait fish into the water, both inside the app and directly on your home screen wallpaper. The shark tracks targets and calculates interception angles, while each prey species uses its own tricks: burst speed, ducking behind coral, or slipping out of the shark's blind spot.
Will it drain my battery as a live wallpaper?
No. When you lock your phone or open another app, the 3D rendering loop pauses instantly, so it uses no CPU or GPU while idle.
Are there really no ads and no tracking?
Yes. Pet Shark has no ad network libraries (no AdMob, Unity or AppLovin), no analytics trackers and no background profiling. We never collect or resell user data.
How do I set the animated shark wallpaper on Android?
Open the app, tap "Set as Wallpaper" and confirm on Android's preview screen. You can apply it to your Home Screen, Lock Screen or both.
Does it run well on older phones?
Yes. In settings you can cap the frame rate at 30 FPS, reduce the render scale to 75% or turn off real-time caustics, which keeps budget hardware above 30 FPS.
Do I need an internet connection?
No. All 3D models, textures, shaders and audio are bundled in the app, so it works in airplane mode.
