O jogo é muito bonito só isso não tem imersão real só coisas pequenas como regular o ph kh th co2 ciclo do nitrogênio e mesmo assim é bugado os 2 Bettas não brigam por território mesmo em aquário pequeno. Quando melhorar esses aspectos eu mudo minha análise pra positiva.

魚の動きは概ね良好ですが、亀は底面でバタバタして動かなくなりフリーズ状態になる。 魚の種類としては各種の海老とタコ及びフグの登場が待たれます。

❤ man, this is awesome. But pls make filters & heater visible too. Despite that, it's almost like watching in real life. 🙏 I love the behavior, they are not just swimming around; they hide, crabs are moving over & under objects, and so on. Very well done.
amazing sandbox, cant wait for the shrimps!
Relaxing!
Це найкращий акваріум! Відчуття неймовірні! Дякую розробникам, чекаю на доповнення! Всім рекомендую.
i LOVE EVERYTHING ABOUT THIS GAME : there are lots of kinds of fish , even more decor so you can build evreything you want. The fish have nice and smooth swiming and the plants bend and sway you can even mix breed fish having so much more verity / But i would like to see biger sizes of tanks more veriety of plants for both fresh and salt water : my conclusion is this game is so good some thing that need to beworked on but as it is i will give it a 8.5 / 10 love it
Very nice game with realistic fishes (and some other animals too) of tons of different species. It's perfect if you love aquariums but can't have one of your own. And the cross-breeding feature is fun to play around with to make unique mix-and-match cross-breed fishes.
As far as pale imitators of 9003's Desktop Life go, this is a step above Smith Micro's Desktop Garden. That said, if Steam did 0 - 5 stars instead of just a thumb up or down, I would give this game 3 stars because it still does not live up to my expectations born from AQUAZONE: Desktop Life. I still miss my rainbow of RGB-genes in solid, tuxedo starburst, grass, and leopard-spotted delta-tailed guppies, and especially wish I could have gotten more than 3 starburst colors (cyan, yellow, white) and delta tails before 9003 went out of business.
