  • Exceptional visual quality with realistic and fluid fish animations that bring aquariums to life.
  • Extensive customization options including a wide variety of fish species, plants, hardscapes, and breeding/lab features for unique creations.
  • Dual modes serve both casual designers (Designer Mode) and detailed aquarium hobbyists (Simulation Mode) with realistic water chemistry and ecosystem management.
  • Highly relaxing and immersive experience suitable for casual players and aquarium enthusiasts to unwind and design without real-life maintenance hassles.
  • Active and responsive developers frequently update the game with new content, community features like Steam Workshop, and improvements based on player feedback.
  • Good optimization allowing play on a range of systems including lower-end laptops and support for 4K and multi-monitor setups.
  • Some UI and controls can be unintuitive or fiddly, such as rotation mechanics and item editing, which may hinder detailed aquascaping.
  • Limited variety of certain content like shrimp, snails, more diverse plant species, unique aquarium decorations, and larger tank shapes (only rectangles available).
  • Fish AI and behavior are realistic but still lack complete species-specific traits and complex interactions, reducing immersion for experts.
  • Simulation features can be complex and inaccessible without tutorials; some water chemistry and ecosystem mechanics need polish or are not fully fleshed out.
  • Lack of progression, goals, or a campaign mode may reduce long-term engagement for players seeking gameplay beyond sandbox creation.
  • Occasional bugs, performance issues on some platforms, and missing visual elements for filtration and equipment lower realism.

    The graphics of this aquarium simulator are widely praised for their realistic, high-quality visuals, including lifelike fish models, natural animations, and customizable lighting that create a stunning and immersive underwater experience. Despite being graphically impressive, the game runs well even on modest hardware. While some users desire further refinement and more content, the overall aesthetic appeal and realism set it apart from other aquarium games.

    • “From the moment you start Behind Glass, the visual presentation captures your attention with its high-quality 3D graphics and lifelike water physics.”
    • “The stunning graphics bring each fish to life, while the extensive species roster includes all the classic favorites you'd expect.”
    • “The realism captured by the graphics and animation is fantastic, and the features and options for customization allow for endless hours of enjoyment.”
    • “Meh, not great. The visuals are good but not as good as what's shown. There's a lack of content; I suppose it is a sandbox, but really there's nothing to do at all. I'm unsure if you can breed fish. I know there's a combination thing, but you can't seem to raise fry. There's no story, goal, or even currency to slowly improve. [PS game devs, I would love to see more betta tail types and fancy goldfish.]”
    • “The graphics in 1080p are fine, but I would like to see better anti-aliasing in the future. It's not terrible though.”
    • “There is always a risk of getting ETS2, where in 10 years neither modern graphics nor real simulation appeared, in fact.”

  • music

    17 mentions Positive Neutral Negative
    35% positive mentions, 47% neutral mentions, 18% negative mentions

    The music in this game is widely praised for being relaxing and soothing, enhancing the peaceful and immersive aquarium experience. Some users appreciate the option to play their own music, while a few mention difficulties with toggling sound settings and desire more music variety or customization options. Overall, the calming soundtrack complements the game's tranquil atmosphere.

    • “This is one of my favourite relaxing games. The soundtrack is properly nice, they're always updating the tutorials, and honestly -- it's helped me a lot in creating the tank I want for real fish friends.”
    • “This simulator is relatively realistic and absolutely stunning. The music is calming, and I enjoy just sitting and watching my virtual fishes exist.”
    • “This simulation (if you like fish) will give your creative mind something to chew on, while you relax and enjoy the peaceful music and the visual masterpiece you create.”
    • “- Music and sounds are difficult to turn off and on; they are also not pleasant.”
    • “- 2D mode music keeps playing unless you untick the box before closing the game.”
    • “- Add more music sounds.”

  • gameplay

    15 mentions Positive Neutral Negative
    20% positive mentions, 60% neutral mentions, 20% negative mentions

    The gameplay is criticized for being limited and somewhat boring, with simple mechanics like automatic cleaning and lacking interactive features such as breeding or tank maintenance. While the simulation offers impressive visual design and customization, it falls short in realistic and engaging gameplay elements compared to similar titles. Overall, players find the gameplay lacking depth and mechanical complexity that would enhance immersion.

    • “Its impressive visual design, extensive customization options, and dual gameplay modes make it a standout title in the niche genre of aquarium simulators.”
    • “I know a lot of people don't like not being able to access all the content straight away, but surely that is what sandbox mode is for. It wouldn't hurt to have gameplay elements, and that is why Aquarist is my favourite fish game. Plus it has got a mind boggling amount of coral & you can even breed & focus on the coral. It is not as accurate & real to life as this sim by the looks of it, but it does still have basic heating, pH & compatible plants & species plus overpopulation & sickness. But this is more real to life by the looks of it.”
    • “- In-depth simulation mechanics”
    • “I wouldn't buy it for gameplay though; even the cleaning of the glass is done just by clicking a button and you can't breed your fish. It's quite boring when you want to do anything besides designing and watching.”
    • “The mechanics are also a bit confusing.”
    • “Currently there are no mechanical objects like filters, scrubbers, heaters, etc. You don't have to actually maintain the aquariums, but it would be nice to have some of those objects even if they were just for show.”

  • story

    14 mentions Positive Neutral Negative
    21% positive mentions, 58% neutral mentions, 21% negative mentions

    The story aspect is generally seen as lacking or minimal, with some users finding it predictable or short and others noting the absence of meaningful narrative, goals, or progression elements to keep players engaged long-term. While the character attachment is appreciated by a few, most feel the game would benefit from a more developed storyline and additional objectives.

    • “The story was a bit predictable at times, but still pretty enjoyable and I got really attached to some characters like Fish and Crab.”
    • “Has a short story campaign.”
    • “Most of the games I have played in the past were quite cartoonish in graphics, and you have to complete tasks and quests to advance to other tanks and fish, which makes it seem more like a job.”
    • “Meh not great the visuals are good not as good as what's shown. There's a lack of content; I suppose it is a sandbox but really there's nothing to do at all. I'm unsure if you can breed fish. I know there's a combination thing but you can't seem to raise fry and there's no story, goal, or even currency to slowly improve. [PS game devs I would love to see more betta tail types and fancy goldfish]”
    • “☐ No story”
    • “- Doesn't have any goals or story to keep players invested for long periods of time”
