Fantasy Aquarium A tank that grows while you work

The loop is simple and it stays simple. You buy fish cards from the shop, drop them in a tank, and wait while they grow. Once a fish is fully grown you make the choice: leave it swimming to earn gold over time, or sell it for a lump sum right away. Gold goes back into more cards, and the cycle turns again.

Since the fish keep growing even while the game is closed, you can check in once a day, collect what piled up, buy a few cards, and be done. It is a game that fits around your day rather than the other way round.

The fish are the point. There are hundreds of species hiding behind the cards, each drawn in bright pixel art, with rarer colours to chase on top. The tanks themselves come in several themes, and decorations from the gachapon add things like a giant kraken looming in the background.

Everything is collected in a proper index, so you always know what you have and what is still missing. Fair warning: the last few rare fish take real patience, and the clicking involved is a lot. Come for the pretty tanks and the slow hunt, not for a quick completion.

This is a game built to sit quietly in a corner of your screen. There are more than ten sets of soft music to pick from, plus built-in white noise, made for working or studying alongside it. The fish drift across their tanks at their own pace, and the whole thing hums along without asking anything of you.

The shopkeeper stays by your side the whole time, a small friendly presence in the corner of an otherwise calm screen. If your desk could use a bit of underwater colour and a looping soundtrack, this does that job well.
