What the developers have to say:

Why Early Access?

“Early Access allows me to work closely with the community to fine-tune core systems like fish behavior, tank management, balancing, and overall feel. Player feedback will directly influence new fish species, decorations, and quality of life improvements as development continues.”

Approximately how long will this game be in Early Access?

“Fish Tank Sim is expected to remain in Early Access for approximately 12–24 months, depending on development progress, community feedback, and the scope of added systems. Considering it's currently being developed by a single developer.”

How is the full version planned to differ from the Early Access version?

“The full version is planned to expand on the current experience with deeper progression. This may include additional tanks, more fish with unique traits, expanded decoration and upgrade systems, new environments, visual customization options, and optional side activities such as fishing. These features are goals and may change during development.”

What is the current state of the Early Access version?

“The Early Access version offers a fully playable core experience. Players can manage multiple fish tanks, feed fish, clean tanks through interactive mechanics, grow and sell fish to earn money, unlock new tanks and fish through leveling, purchase tank upgrades such as filters and aerators, trade large orders using the trade menu, and a experience a day/night cycle with ambient forest sounds.”

Will the game be priced differently during and after Early Access?

“Fish Tank Simulator is expected to increase slightly in price after leaving Early Access, reflecting the addition of new content and systems.”

How are you planning on involving the Community in your development process?

“I plan to actively involve the community through Steam discussions and Discord by gathering feedback, engaging in discussions, and using polls to help guide future improvements and priorities.”

- Performance is not yet fully optimized.
- Core gameplay loop is not final, however it's complete and playable. It's just that gameplay-enhancing features are planned to be added. (Relaxing Fishing for example is planned to fill the wait time)

FTS is a game made by a solo developer, created on October 8th, 2025. It’s my 4th game attempt after 3 years of game development. The main inspiration was a Facebook game I loved called Fishville. However, that game wouldn’t work well as an offline, session-based game, so I added more features over time, and it became its own standalone title.

If you have any questions or would like to provide feedback, I’d greatly appreciate it, just join the Discord and share your thoughts there. I genuinely hope you enjoy my game from the bottom of my heart!

More will be described as the development process progresses.
