Bought this trying to scratch the itch for my aquascaping desires. It didn't quite scratch it. Yea there's a bunch of fish. But the plant selection leaves a lot to be desired. The rock shapes are okay but while there's variety in shape (while not really enough), The rock styles feel subpar. Typical aquascaping style rocks aren't really featured much, and they just feel like chunks of rock. I also just really did not like the fish behaviors. Bottom dwelling fish swimming in the middle and top sections of the tank most of the time threw me for a loop. The mechanics are also a bit confusing. You have buttons for rotating scape items but also an xyz axis to rotate it by mouse. If you utilize the buttons the object can only rotate one direction but also TILTS ITSELF AT TIMES, so adjusting things like rocks that aren't entirely flat is a pain. Trying to flatten or round out the landscaping is difficult. I could not for the life of me get the landscaping to look the way I wanted it in the 45 minutes I played. If you can get past the controls, limitations of hardscape and plant options, and corydoras that think they're gouramis, it's a great game. Definitely something to play if you wanna make a cool looking fish tank and aren't obsessive over everything being to the "t" accurate.

同じゲームのAquarium Designerと比べて、 こっちの方がやれることが多い。 あっちの方がシンプルなような気がする。 あとは見た感じの好みとかかなぁ。 安い方を買うのもアリかも。 でも自分的には両方買ったが、 こっちの方がおすすめかなぁ。。 退屈しないし。
symulator petarda , panowie dodajcie (Pterois volitans) pliz 10\10 super polecam !!!
molto bel fatta la grafica e il layout generale. Da migliorare la limitata scelta delle piante e la mancanza di gamberetti e lumache. Per la simulazione buona ma si può rendere la gestione ancora più realistica
我感觉不好玩,只有装饰水族箱这个功能,还有放鱼,繁殖鱼,没管生殖隔离的啊,好奇怪,感觉新手指引也有些欠缺,有些键位都不知道怎么按。
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.
This game is impressively realistic. It can be as simple or as complicated as you'd like. Swapping between a creative mode, and simulation mode seamlessly. I've been using this to learn how to properly cycle my own aquarium. I also thoroughly enjoy the breeding mode. You can make the fish look as insane, or beautiful as you want. The only downside is controller support is limited, but not awful. I play this on my steamdeck from time to time. It runs well enough, but the controls can be frustrating at times. If you're a fish enthusiast like me, I cant recommend this enough.
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
