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.
I am just enjoying it as a aquarium display, very realistic animations and sounds. I set my aquarium size to match my monitor dimentions and run it as wall art. There is a simulator in the game, and found it matched real requirements of the fish. I have no interest in that though, It looked complete, but maintaining water quality, temps and cleaning tank are why I no longer have a real aquarium. Don't want to do that. Good news, you can turn it all off. And just put the fish, plants and other decoration in the tank and let it run. I did like the cross-breeder, but sometimes I just would have liked some alt skins for some of the heavily hybrid species, like guppies, bettas and angelfish.
Back in the day, I fell in love with Maxis' El Fish. Since then, I have been seeking the next best iteration. This led to the purchase of many aquarium screen savers and fishing games. At last my quest is complete in 4k glory! It looks terrific, plays smooth, and just keeps getting better. It works as a creative toy to chill to as well as a way to see what taking care of exotic fish would be like without mess, disaster and mass death. My wife loves it more than I do. I Whole-heartedly recommend this wonderful product! Also, I run Linux Mint with zero issues.
This is the best aquarium design game in the store right now. Just take a look at the workshop at what the community have made. There are moments that are absolutely photorealistic. These stills don't do justice to the motion of the fish, however, which are the most lifelike of any game in this niche. Watching your betta fish randomly assault your school of corydoras, or how they all scramble when you drop in some food...these are much more than just cardboard cutouts of fish hastily slapped in as decorations. This is the first of these sims that I've played where I could easily replicate my own freshwater tanks from home, from the decorations, plants, substrates, down to making custom crossbreeds of fish to get ones that looked like my own. I have a tank in-game that houses replicas of all the fish that have passed away in our fishroom in the last three years, and it serves as a potent reminder of the lessons I've learned in the hobby the hard way, and the great friendships our family has shared. This wouldn't be possible if the tools were complicated or obtuse, or there weren't enough variations of decor and species to choose from. I don't play these games to simulate water parameters and turn the tank into a tamagotchi or idler game. I haven't tried any of the systems in this title to replicate those aspects, so it may be a blind spot of this recommendation if they don't deliver in the same way as the design elements. For me, it's all about designing a great aquascape, populating it with the right community of fish, and turning the whole thing into a living wallpaper and letting it shine. The different camera modes and '2d' mode make this game into eye candy and give a real sense of accomplishment when a build is finished. You can get everything for about 20 bucks, so cheap for the goods this game delivers, I absolutely recommend this game especially on a sale. Thanks for reading!
I liked the UI and the choice of tank sizes and shapes, what i dislike is that there are no shrimp and snails and some goups of fish need more for example freshwater gobies there is currently only one species and they should add peacock gudgeons as another species for that group or stiphodon gobies. (: great game 5/5
