Draw Alive: Fish turns your doodles into a living aquarium. Sketch any sea creature on a piece of paper, photograph it with your phone, and import the picture — within moments your drawing is swimming through a foggy, caustic-lit 3D tank with movement matched to its species.

Nine kinds of creatures can come alive — fish (a whole family of subtypes from clownfish to shark), sea turtles, jellyfish, crabs, seahorses, squid, octopuses, manta rays and whale sharks. A built-in classifier guesses what you drew and shows its confidence, but you can always correct it; pre-cut transparent PNGs work too.

Switch between Build Mode and Play Mode at any time. In Build Mode, import creatures, arrange coral reefs and environments, and decorate your tank. In Play Mode, the editing tools vanish and your aquarium becomes a living exhibit with cinematic cameras — free orbit, glass-front view, diver's perspective, and a self-directed showcase. Press a key to capture a clean screenshot.

Your tank is never empty: a living ecosystem seeds balanced populations of fish and marine life that swim, school and surface on their own, with occasional dynamic events like jellyfish blooms and manta fly-bys. Draw Alive: Fish is a calm, single-player sandbox — no accounts, no economy, no multiplayer. Just you, your drawings, and the sea.
