About Tiny Aquarium Mobile

Tiny Aquarium is Lunheim Studios' cozy fishkeeping game from Steam, on iOS since May 28, 2026 and Android since June as a $4.99 paid app — hatch, breed and catch 120-plus fish that grow while the app is closed, decorate the tank, fish with strangers, trade on a player market and join events. No ads, no purchases. Reviewers call it addicting and better than anything like it; they also want a Steam link, more players in the mobile lobbies, and menus built for thumbs.

Tiny Aquarium Review: A $4.99 Fishkeeping Idle Game, No Shop, Small Lobbies

One Egg, an Empty Tank, and 120 Fish to Chase

The loop is idle fishkeeping with a collector's spine: you begin with a single egg in an empty tank and build outward — hatching, breeding for gene mutations, catching fish in a rod-and-boat minigame you upgrade, decorating from a market — while the fish grow in real time even when the app is closed, so a few minutes' visit is the intended session. There are 120-plus species, real ones and invented ones, each with a fact about its real counterpart. Online, you can visit other players' tanks, trade fish and fish together, or ignore all of it. The reviews are affectionate: a June 25, 2026 App Store five-star calls it addicting, far better than any game like it, with no purchases or ads; a September 12 Play four-star calls it a solid port. Rated 4+ and Everyone, English only, 278 MB on iOS 13 or Android 6.0.

A PC Port on a Phone: Mutation Drops, Bait Descriptions, No Steam Link

The port shows its origin. An August 3 Play four-star with four votes finds item descriptions thin and using items on fish obviously designed for a mouse, mutation drops especially, their percentage display so large it hides the fish you want to tap; the September 12 reviewer wants bait explained and notes gene descriptions that linger. The bigger disappointments are structural: May 31 and July 17 reviews bought the app to check their Steam aquarium at work and learned the developers chose not to allow cross-platform profiles; an August 25 five-star rarely sees four people in a mobile session, which leaves the market slow; a September 1 Play review with 16 GB of RAM runs it perfectly but says fishing with others heats a Razr and fails on low-RAM phones. Ratings: 4.5 from 53 on the App Store, 4.2 from 129 on Play.

$4.99 Once, No Ads, No Purchases, Version 0.0.80 on Android

The economy is a price: $4.99 on the App Store and $4.99 on Google Play, no in-app purchases, no ads, no loot-box flag — the June 25 reviewer checked. Apple lists no tracking; Google's data-safety card lists Personal info, App activity and two other types collected, which fits an online market and events. Version numbers tell the port's age: 1.0.7 on iOS and 0.0.80 on Android, both from June 25, with the studio a small one — a one-person company on Google Play — and the September reviews asking for more events. Prices are regional.

Pros

120-plus fish to hatch, breed, catch and learn about, growing while you are away

$4.99 once with no ads, no purchases and events that keep cycling
Charming pixel tanks and a fishing minigame with rod and boat upgrades
A solid port of the Steam game, per September reviews

Cons

No cross-platform profile with the Steam version — progress starts over
Menus and item use built for a mouse; mutation drops hide the fish you tap
Small mobile lobbies and a slow market, per an August review
Mutes all background audio and heats phones during group fishing

Verdict

A 7.0 for a gentle, generous fish collector sold for one small price, brought to phones with its PC interface intact and its multiplayer half-empty. Take it if you want an idle aquarium with real breeding and no shop, and are happy with your own tank. Skip it if you play it on Steam and hoped to continue the same fish, or if trading and group fishing are the point.

Gameplay7Collect, breed and decorate at your own pace, with a fishing minigame and events for texture.

Controls5PC interactions on a phone — hidden buttons, oversized tooltips, items hard to apply.

Replay value7Rare fish to chase for a long time, mutations, events — and lobbies too small for the trade half.

Graphics & sound7Cute pixel aquariums; audio that kills your podcast.

Monetisation9One price, nothing else — checked by its own reviewers.

Frequently asked questions

Can you play Tiny Aquarium offline?

Your own tank, yes — fish grow in real time whether the app is open or closed, and there are no ads or purchases to verify. Visiting other tanks, trading, fishing with strangers and events are online, and a September 2026 reviewer found group fishing the demanding part.

Is Tiny Aquarium free?

No. It is $4.99 on both the App Store and Google Play, paid once, with no in-app purchases and no ads — a June 2026 reviewer looked and found none. The Steam version is a separate purchase with no shared profile. Prices vary by region.

What phone do you need for Tiny Aquarium?

iOS 13 or newer with 278 MB free, or Android 6.0 or newer — low floors for a pixel game — but group fishing is another matter: a September 2026 reviewer with 16 GB of RAM says lower-RAM phones struggle in shared sessions and even a Motorola Razr 2025 heats up. Solo tanks run on anything.

Can you play Tiny Aquarium with friends?

Yes — visit their tanks, trade fish, fish together and join events; Google Play flags that users interact. The catch is population: an August 2026 reviewer rarely sees four players in a mobile session and finds the market slow, while PC lobbies look full. Steam and mobile players cannot share a profile.

How much time does Tiny Aquarium take?

A few minutes at a time, by design — fish grow while you are away, so a check-in feeds, breeds and decorates. The long game is the collection: some fish you will chase for a long time, per the listing, plus events like the conservation month. Reviewers describe hours lost anyway.
