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.

Slow down. Keep some fish.

I love this app. I love that it supports voiceover. It’s not every day you see a game that supports voiceover. I have a couple of I have a couple of suggestions for this app. I know that description it says the fish can’t die, but I know that they can get sick and like my suggestion was that like you could create a setting or a switch in settings that like when it’s on when Health reaches zero the fish do die another suggestion I have is for my old age. is four is for fish to die of old age. once we just certain age they die. and they have a legacy. this can be like a setting too like this could be a whole death section in the setting and in the settings. another suggestion I have is to make plus a lifetime subscription instead of a monthly and yearly subscription
Developer Response
Thanks! A setting where fish can die is a good idea, I'll think about it. Something close to a legacy is already there: when a fish is a close friend you can send it off and keep a keepsake card of it. And lifetime Plus is a good idea too, I'm going to add it.
Really fun fish game
