Aqua Nook - Aquarium

Build a tiny world of water of your own inside a small aquarium — a first-person 3D aquarium-making app. There's no score and no way to fail. Choose a tank, lay down the substrate, arrange rocks, driftwood and plants wherever you like, then release your fish. The hands-on process itself is the point — a slow, calming experience to sink into. ■ From the tank to the layout, your way Choose a standard tank, round bowl, large tank or cube tank, then pick one of five substrates. Place and adjust 12 kinds of stones, wood and plants — position, rotation, size and tilt are all up to you. You can also start from a ready-made sample layout. ■ Fish that keep swimming Release seven kinds of freshwater fish, such as neon tetras and angelfish, in any mix and number. They school together and steer around your hardscape as they swim. ■ Finish with light and scenery Pick a background — city, seaside, sunset lake or moonlit sea — and a light color to set the mood. Ambient music is included. ■ Admire it, and keep a photo Watch your finished tank slowly rotate in viewing mode. Save it to your photos or share it. ■ Keep your work in the Tank Rack Every tank you make is saved to the rack, so you can look back on it or continue editing anytime. Your data is stored only on this device. ■ About ads A small banner ad appears only on the title screen and at the bottom of the rack (never while you're making or viewing a tank). A one-time "Remove Ads" purchase hides it, and the "Tropical River Pack" (one-time purchase, no subscriptions) adds fish, driftwood, stone, plants and substrate. No failure, no penalties — just a quiet moment to focus on working with your hands, whenever you have a little time to spare.
