Tanklet: Idle Fish Aquarium

Breed & collect koi betta fish

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Fully playable with VoiceOver, and the tank has sound now. Grant your fish's daily wishes, welcome weekly collectors, fill field notes on 50 species. Fish never die. 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 a second and third tank: 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.

A few fixes from VoiceOver players' feedback: · Expedition is now in the More menu too, no need to dig through Storage. · When the water needs changing, VoiceOver tells you where: More, then Clean. · On smaller iPhones the More menu no longer covers the buttons at the top.
