Це найкращий акваріум! Відчуття неймовірні! Дякую розробникам, чекаю на доповнення! Всім рекомендую.
Absolument splendide. Un choix incroyable de décors et poissons, une personnalisation à l'extrême pour un rendu bluffant de réalisme, des dimensions du bac à l'aspect final souhaité. La possibilité de créer des aquariums eau douce ou eau de mer avec les spécificités, le choix de réaliser un bac complexe avec chimie de l'eau et tout ce qui passionne l'aquariophile ou profiter du moment de détente en musique avec son aquarium en fond d'écran (choix possible de l'adaptation au format d'écran lors de la création du bac). L'utilisation est simple et parfaitement guidée. Je recommande vivement.
todo me encanta, gracias por regalarnos actualizaciones gratis con nuevas especies. y con gusto compre el dlc q ha salido. esta muy bonito, quisiera pedirles por favor creen mas objetos de decoracion seria muy genial gracias a todo el equipo de behind glass
We need sea fish!!!

had niet verwacht dat dit zo ongelooflijk mooi zou zijn, alles heel realistisch, bijvoorbeeld een schildpad die met zijn hoofd boven water komt, vissen die op elkaar reageren en hoe ze overal voorbij zwemmen echt heel mooi gedaan, en planten passen zich aan aan bijvoorbeeld een rots of tak, het glas wordt ook realistisch vies.. en ik heb niet eens een hele moderne computer met een dure grafische kaart
グラフィックは綺麗なのだが、実際の魚の行動が全く再現されておらず、なんか違うなーと違和感しか感じない。もう少しそれっぽい動きを再現してほしい。
what if you guys who made the add the fish can jump out of the tank and you can pick them up with the mouse and add pufferfish pls
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
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.
