Mokizen is a 3D aquatic and terrarium world that runs directly in your browser. You build your tank realistically: choose the tank and substrate, place rocks, driftwood, moss, aquatic plants, shrimp, and fish, and then admire the whole scene with real-time lighting and water. There are two types of users, and both fit well with Mokizen.

For aquarium and terrarium enthusiasts: plan your layout before purchasing. Players often have to buy rocks and driftwood before knowing whether the layout is beautiful or not, and it's very hard to imagine how the plants will grow. Mokizen allows you to measure real sizes in cm, see the tank develop over a 90-day timeline, and then buy according to the material list.

For those who are not allowed to keep fish or plants indoors: if there’s no space at home, if a spouse says no, if rental restrictions apply, or simply if you are too lazy to maintain them. No worries, you can keep a virtual tank right on your phone, computer, or TV. No water changes are needed, no filtration, the fish don’t die, the moss doesn’t rot, and no one complains. Just turn it on to have a beautiful aquarium to admire, or open it on the TV as a relaxing background for the living room.

Main features:

• Real-time 3D editor using touch and mouse: place rocks, driftwood, moss, plants, shrimp, fish, lights, display sizes in cm.
• View the tank's development over a 90-day timeline, complete with care guides for each species and a shopping list.
• Over 40 sample worlds (Iwagumi, Dutch, blackwater, Ha Long style rocky mountains, Zen gardens...) with material lists.
• Share and remix other people's tanks via a link; export images or videos; view tanks in augmented reality (AR).
• Replay the tank building process in timelapse for sharing.
• Available in 7 languages; runs on the web (phone, computer, TV with a browser), iOS app, Telegram Mini App, and dynamic wallpaper on the computer.

How to get started: open mokizen.com on any device with a browser, no installation or account creation is needed to view and try building; iPhone users can install the app from the App Store. Free to use, with a Pro package available for advanced features.

What sets it apart: available tools are usually just 2D images or heavy software. Mokizen is real-time 3D, uses real sizes, and runs directly on the web.
