Fun time to spend with this. Reminds me of going over to my aunt's place when she was alive, I would put on a YouTube video of a fish tank on her screen while we there and the whole family would talk... I miss those days... anyways... beautiful game even though its just a tank full of fake fish.
Zen Aquarium may be the most aptly named game on Steam. If you are looking for a zen-like, tranquil experience, delivered via an aquarium, then Zen Aquarium is for you. The Zen Aquarium is not actually a game, more akin to an experience. There is no 'fish combat' or 'exploding fish'. This fish are colorful and accurate. Most of all, tranquil. Pros A selection of aquariums to choose from. Nice selection of music to select. A solid number of ASMR sound overlays to compliment the experience. Low CPU utilization. Cons (more like quibbles, no real cons) To get the most from the experience, a reasonable quality of speaker or headset is helpful. The better the monitor the better the experience (sort of an 'of course' observation) A great background to a room or reading space. With more than 50 hours of use, I recommend this product completely.
6.5/10. To be clear, this isn't really a game you play, you don't do anything. You just wait for the fish to drop and enjoy the music and visuals I use it as a background for when I really have to focus on my work/studies. The ability to customise the playlist and background sounds or to mute it to put your own music in the background is great. I just wish there were more varieties of fish and maybe other types of sea animals like shrimps or little crabs.
This reminds me of an old fish tank screensaver I had was on Windows XP.. but up to date, and is only $5 many more fish, many tanks to choose from.. just wish there was better interaction, maybe drop food in f.e. It’s be cool if they figured out how to make this your screensaver…
