‥∴ Bringing the Allure of Goldfish Closer ∴‥
This app is the culmination of the developer's childhood dream: to bring the beauty of goldfish to life through programming. After 15 years of development and refinement since the release of the previous version, "Wa Kingyo," this app strives to reproduce the elegant and charming behavior of goldfish. From the gentle movements of their fins to the pursuit and munching of food, I hope you feel the enchantment of these captivating creatures.

Ratings and reviews

Exactly what I needed~ ♡ I have a hard time focusing at work cause I need something passively "existing" near me to feel productive. Sometimes youtube, D&D, music, this weird aquarium game with creepy creatures. Otherwise, I'd be checking my phone constantly and getting hella distracted. Thank you for the tank dust option. It bothered the he// out of me. I treated myself to a 3.99$ game to justify a hard working week and now I need to budget around buying additional fish 😅 Maybe axolotls. Ty♡

It's good but would have liked to know in advance that additional fish cost beyond the two you get (black and white) for the $4 purchase cost $2 each. Also no live wallpaper seems like a letdown.

Gorgeous app, very calming with simple but very pleasing options.
