# Aqua Tank — 3D Ecosystem Aquarium **Short description** A living 3D aquarium in your browser: fish, plants, caustics and light shafts, with feeding and care one click away. **Detailed description** Want a quiet underwater corner between meetings? Aqua Tank packs an interactive 3D ecosystem into Chrome. Open it from the toolbar, expand to a full window, or pin an optional float on ordinary web pages. The tank hosts fish, invertebrates, plants and décor, with volume water, surface ripples, sand caustics and light shafts rendered live. Place species, feed, tune light / current / color temperature, save a screenshot, and dim the scene with night mode. Layout and preferences stay on your device; core care works offline. The UI supports Chinese, English, and Japanese. Optional Pro raises species capacity and unlocks exclusive species, follow-cam, ambience presets, richer bubbles, and hands-off care extras. **Why it fits** • A real-time 3D tank you can open instantly • Three entries: popup, full window, optional page float • Feeding and environment controls anytime • Data stays local — no sign-in required to start • Chinese, English, and Japanese UI from install **How to use** 1.
