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.
24+ hand-crafted species, each with its own silhouette, fins and temper.
Collect
From clownfish to golden arowana — fill the album, chase rare color variants and elusive shinies.
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.
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.
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, zero data collection. 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.
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.
