A tiny living aquarium in your pocket.
Feed your fish, keep the water clear, and watch a hand-painted tank come alive. Collect, hatch, breed — and come back to coins, because your fish never die.
Free to play · No ads · No account needed
Three small moments a day.
A pinch of food sinks from the surface. That's the whole ritual — a minute in the morning, a glance at night.
Feed
Scatter food and watch the school rush up. Well-fed fish stay bright, happy — and productive.
Tidy
A quick brush keeps the glass clear and the water quality high. Clean tank, thriving fish.
Collect
Fish earn coins around the clock — even while the app is closed. A friendly note tells you what you missed.
Mid-water is where everyone lives.
68 hand-crafted species from five habitats, each with its own silhouette, fins and temper.
Collect
River, mangrove, open sea, coral reef and the deep — from clownfish to the oarfish and the goblin shark. Fill the album, chase rare color variants and elusive shinies.
Give each habitat a tank
Open more tanks and pick their water: freshwater, mangrove, saltwater, coral, or a mix of everything. Fish living in their own habitat breed rare colors more often and bond with you faster. Change a tank's water whenever you like.
Breed
Pair two fish and the fry inherits size, hue and pattern — with the occasional mutation worth bragging about.
Hatch, with honest odds
Egg drop rates are shown before every purchase, and a pity system guarantees rare finds.
Drop by a friend's tank.
Swap friend codes and swim over. Nothing to type, nothing to chat — just tanks.
Visit and like
Look around a friend's tank, see what they've collected, and leave a like. Or wander into a stranger's tank someone chose to share with everyone.
Feed a friend, send a guest
Feed a friend's fish once a day, and they'll find a little note next time they open the app. Send one of your own fish over as a guest to swim in their tank for a while.
You decide who sees it
Visiting is off until you turn it on. Then choose friends only or everyone, report or block any tank, and switch it off again any time. What gets shared
Sometimes the outside world swims in.
Guests to host, friendships to grow, treasure to chase.
Rare visitors
A wild fish may drop by. Feed it, keep the water clean, set out the decorations it loves — treat it well and it stays for good. The rarer the guest, the pickier it is.
Personalities & bonds
Greedy, shy, playful — every fish has its own temper. Greet them daily and serve their favorite treats; close friends share little stories and gifts.
Treasure expeditions
Send one or two fish to the reef, a shipwreck or the deep abyss. Hours later they surface with coins, decorations — sometimes even pearls. Strong bonds bring better luck.
Seasons
Each season brings a fresh set of weekly tasks and its own limited egg, and calendar collections — like Halloween — come back at the same time every year.
A little arcade behind the rocks.
Three short games for when you want to play a bit more. All three can be played with VoiceOver.
Shark Dodge
Fish drop down the lane — swipe freshwater ones left and saltwater ones right, and never touch the shark. With VoiceOver on, a low beep means left, a high beep means right, and an alarm means shark.
Bubble Claw
A real-looking claw machine full of bubbles. Aim, drop, and keep whatever comes up: fish, plants, even plush toys.
Reef Match
Match-three across hand-made levels, with treats and decorations waiting at the milestones.
It gets quieter the deeper you go.
Everything down here is designed to let you relax.
Your fish never die
Neglected fish get hungry, grumpy, even sick — but food, clean water and care always heal them. A night away is a reward, not a punishment.
The tank works while you're away
Coins keep accruing with the app closed — up to 8 hours per absence, 24 with Tanklet+.
No ads, nothing tracking you
No third-party SDKs — only anonymous usage counts you can turn off. Just water and fish.
Your save is yours
It lives on your device and in your private iCloud. We run no servers and never see it. Visiting friends shares only a snapshot of one tank, and only if you turn it on.
A lantern in the deep.
Tanklet+ is comfort for devoted keepers — never pay-to-win power.
The whole game is free forever — Plus is optional.
Monthly or yearly, auto-renewing, cancel anytime. Prices are shown in the App Store in your local currency.
