Really soothing experience. Just don’t go in there expecting a game. Think of it like a real aquarium except the fishes don’t crap all over themselves and die of neglect. It is NOT a gamified focus tool like Spirit City where you stress yourself out micro-managing your ‘stress free’ haven.

It’s very much an idle journey, put it in the background, and enjoy the soundscape. Take a fat nap, reward yourself.

Put it on your TV and relish in your guests asking you where you bought such a thin aquarium and how you feed the fishes because they’re so stupid they don’t understand the concept of a screen. What a bunch of shrimpletons.

It can be odd to fight the natural instinct to want to interact with the aquarium (and you very much cannot), but perhaps it’s the part of the journey towards zen mindfulness.

Some suggestions and wishes:
• Add a way to quick-swap between aquariums instead of going through save/load menus
• Add little thumbnails next to Load/save slots to show you which aquarium is which
• Auto-save would very much be appreciated as well. Hate committing complete fish genocide when closing the app by mistake
• A few more default tracks and the ability to automatically shuffle songs so it doesn’t loop the same one over and over when having it in the background for a while
• Selection of pre-mixed “curated” ASMR soundscapes similar to BetterSleep. Would preserve the ‘passive play’ approach while still adding a lot more lasting appeal for those using it to relax or sleep or meditate
• Ability to mute the ‘fish spawn’ bloob sound effect. If you load an aquarium with 60 fishes, it’s just a nonstop army of loud bloob bloob bloob. Shut up, you’re fishes, what the hell. Nobody’s drowning, nobody’s coming to your rescue
• Add an aquarium that has a giant picture of a cat staring at those fishes because who needs ASMR when you can embrace the comforting permanence of dread
• Preserve sound settings from aquarium to aquarium when it comes to music volume (on/off)
• Add an aquarium with skeletons of fish for Halloween and goth audiences. What is more zen than the ultimate silence of death?
• Add an aquarium with day/night cycle that matches your own, to remind you of the inevitable and unstoppable march of time
• Add a “flush the toilet” button so that your kids can activate some of their core memories of dropping Bloobie the goldfish down the sink. Who needs zen when you can do twenty years of therapy?
• Make fishes kiss like The Sims
• Allow me to name my fishes to turn them into superstars: Marlin Monroe, Tuna Turner, Sharkira, Eelton John
• Imagine being that blue/yellow fish and being the only suppository-looking ugly fish mofo in a fish tank. Yikes and also lol
• Clicking on the fish icon in the top left should toggle fish spawn on/off
• Game is quite a memory hog on Mac at the moment even at lowest settings, which is a bummer for a companion app especially if I want to feel zen when Blender crashes all the time

Consider adding a variety of sea creatures (DLC) such as clams, pearl oysters, crabs that burrow into the sand, shrimp, axolotls, small stingrays, baby sharks, a tiny island with mudskippers, squids, octopuses, jelly fish, night mode, deep sea mode, and glowing fish etc, and other marine animals beyond just fish.

This so called "game" still does not meet my expectation even though my expectation is just a screen saver. I hope this would be the answer for having realistic virtual aquarium while working. It is not.

First of all, there is 0 interaction, which is fine. That works as advertised. But at least give us some set up freedom.
We can only choose the pre-built tank scenery. We stuck with saltwater fish. There is no freshwater fish which means we are losing a big chunk of fish that we can put in the tank. (for now). I doubt, there will be one in the future. There is a jungle theme in the "coming soon" session, but the name of the tank is still "Ocean, shore, lagoon, etc.".

We should at least has some controls like, how many fish we want in the tank, which type, and how many of each type.
And are we allow fish to swim outside the edge or not. A step further, let us decorate the tank would be great.

Second, this App works perfectly only when you have more than one horizontal monitor in your set up. If you use one monitor, this is wasting your time. You are losing your working space. Shrink the App screen and your plant & fish shrink. You won't see a thing. And the screen will always be locked at 16:9 or 16:10 ratio.
If you have one vertical, one horizontal like me. Your main monitor (horizontal) will be wasted. It would be a lot better if we have vertical tank or let user adjust the view freely. The square or vertical rectangle would not take too much work space.

If this was designed for relaxing, calm interaction. Dev should consider the situation where users turn this App on while working.
For now, we can't work if this is on.
