What is Joyquarium?

This single-player idle aquarium simulation has you raise and feed fish manually or through an automatic AFK system. Sell grown fish or keep adults for passive income, then buy fry packs, collect new species and variants, and arrange plants, driftwood, and stones in your tanks.

For you if...

+you enjoy low-input idle progression and background play
+you like collecting fish and decorating aquarium tanks
+you want both active and automatic ways to progress

Not for you if...

−you want detailed, hands-on fishkeeping simulation
−you want varied interactions instead of repeated feeding and selling
