🐟 Aquarium

Six kinds of fish — clownfish, blue tang, angelfish, neon tetra, goldfish & guppy — school by three simple rules: separate, align, cohere. Move your hand to shoo them; click to scatter food and watch them swarm.

Tap the water to scatter food right where you touched — the school swims over to it; hold and drag to keep sprinkling. Release a 🦈 shark to hunt the school. Turn on 🎣 Catch to switch the water to scooping mode, then tap a fish.
