Tanklet is a cozy aquarium game where you raise a tank of fish that's truly yours. Feed them, clean the tank, keep the water healthy, and watch them drift through a beautifully rendered aquarium — all the joy and companionship of fishkeeping, none of the cost or mess. ■ Care for your fish Feed on schedule, clean the tank, and manage water quality. Well-cared-for fish stay healthy, happy, and earn more coins. Neglect them and they get listless or sick — but good care always brings them back. Your fish never die. ■ Rare visitors Wild fish drop by from time to time. Feed them, keep the water clean, and set out the decorations they love — treat them well and they may stay for good. The rarer the visitor, the pickier they are. ■ Personalities & bonds Every fish has its own personality. Greet them daily and serve their favorite treats to deepen your bond, unlocking little stories and rewards. ■ Collect & breed From clownfish, blue tang and angelfish to golden arowana and koi, collect distinctive species and fill your codex. Breed pairs for offspring, with a chance at rare variants and shiny fish. ■ Eggs with honest odds Hatch mystery eggs for new species — drop rates are disclosed before every purchase, with a pity system that guarantees rare finds. ■ Send fish on treasure hunts Pick 1–2 fish for expeditions to the reef, a shipwreck, or the deep abyss. Hours later they return with coins, decorations — sometimes even pearls. Strong bonds and healthy fish bring better luck. ■ Make the tank yours Buy and freely place plants, driftwood, rocks and more. Resize, restyle, and decorate your tank exactly how you like it. ■ More tanks, real ecosystems Save up for more tanks, up to 6: freshwater, saltwater and coral ecosystems each boost matching fish. Every tank has its own theme and decorations, and fish can move anytime. ■ Ambient Mode: put your tank in a room Hide the interface and let your tank live in a warm little room. Nine rooms to swap — an indigo moon window, a brick loft, a green library, a coastal cottage… each room's light truly falls into the water. Keep the screen on and it becomes living furniture. ■ Grows while you're away Close the app and your fish keep you company while coins keep accruing. Come back to collect offline earnings and see what happened. ■ Calm, anywhere A Home Screen widget brings your tank to your desktop; soft water-sound ambience helps you unwind; iCloud keeps your tank in sync across devices. No ads, no third-party SDKs, zero data collection — your tank is yours alone. Subscribe to Tanklet+ for double coins, offline earnings extended 8→24 hours, auto-care while away, a monthly pearl gift, and exclusive decor. Slow down. Keep some fish.
