In this game, you breed fish and keep them happy. Their joy are an in-game currency, which you can use to buy fish eggs, food, backgrounds, boosters, plants, and aquarium decorations. You can also purchase small containers for breeding fish, upgrade, and unlock new aquariums.

Each fish has its own preferences for water temperature, salt content, and lighting levels.

You don't need to keep the game open or minimized in the background. Your fish continue to enjoy themselves, generating in-game currency, even if you've turned off the game and are offline.

The game is fun and a bit addictive if you're into this kind of game. Some annoyances are that all the tanks seem to share the same settings, so when you turn salt on for one, it does it for ALL the tanks, which is annoying and makes ZERO sense. Some of the instructions are unclear as well. Mostly it's a fun game, though I would wait for a sale, since the mechanics make it a bit frustrating.

As a disclaimer, I recieved this game for free in exchange for playing it on twitch.

Positives: The art style is adorable and there are 3 music variations to choose from. The concept of breeding the fish to try to fill out the book of variants is interesting. The game does progress time-wise when closed, without needing an upgrade for that.

Negatives:
Progression is EXTREMELY slow. I play a lot of idle games and this one is by far the slowest, both for currency and breeding.
Tutorials- very basic, not very clear. This has been updated since the game came out in early access, but they still could use work. I couldn't figure out how to move fish to the breeding tank for quite a while, despite it only being a few clicks.

I think the game has good bones and with some tweaks could be a decent idler, but as it is I cannot recommend it.

Latest updates

Background Fish!

189 days ago

It's Taskbar Treasure Week and we have a new background mode. Sadly, it only works for Windows machines, but pressing F12 or the button on your screen will move your fish to your wallpaper, where you can watch them swim happily while still doing other things!And as usual, a new set of fish parts was added ;)

Premium Eggs and Some QoL Updates

218 days ago

You said the premium eggs were not premium enough and sure not worth the price if all you would get from them is another fish you could breed from the starting set anyway. This is now fixed, and the premium eggs are back to the fish store.PLEASE NOTE: the main difference in those premium eggs are the skins. These skins can't be obtained in any other way than hatching premium eggs or breeding premium fish. We will be adding more premium skins in the future and probably more tiers of premium skins as well. There will be no premium fish body parts.Other than that, two new sets of fish body parts were added.Finally, we have added some QoL changes: you can now push both fish in the breeding aquarium to the atlas to examine the possible breeding outcomes and it's also possible to filter the outcomes to see how many of them you have not obtained yet.
