AquaKeeper: Aquarium Sim

AquaKeeper is a realistic 3D aquarium simulation where you build and maintain a tank yourself. Pour substrate, place rock and driftwood, fill the water, plant aquatic greens, and bring in fish. Two modes - Easy mode: focus on decorating. Place rock and plants freely, see water stats on screen, and manage the tank with one-tap actions. - Fishkeeping simulator: the hobby recreated with hands-on tools. Water quality is hidden, and you learn it by running reagent tests. What you do - Pour substrate by the cup and let it settle at a natural angle; sculpt, dig and level it by hand - Place rock and driftwood. Unsoaked driftwood floats, sinks after a few days, and tints the water - Fill the tank with a jug. Pour without a plate and you dig craters and cloud the water - Plant and replant aquatic greens with tweezers. Too shallow and they float, too deep and they rot - Manage water quality and temperature with filters (sponge, hang-on-back, canister) and a heater - Run reagent tests for ammonia, nitrite, nitrate and pH while the tank goes through the nitrogen cycle - Keep and breed 5 guppy color strains, and feed them by hand - Deal with fishkeeping risks such as ich (white spot disease), low oxygen and overcrowding Look and feel A volumetric water shader, LED caustic shadows, and lighting that changes from day to night. On mobile, touch controls and quality presets (LOW to ULTRA) adjust performance to your phone. AquaKeeper needs no account and no network connection. Save data stays on your device.
