"Fish Tycoon" is a real-time game. This means even when you aren't physically playing the game, things continue to happen (fish grow, die, get hungry). If you aren't going to have access to your computer for a day or more, you should stop time so you won't lose all your hard work.
How to Stop Time
- Go to Menu Screen.
- Click Options.
- Under Game Speed, select Stop Time
- Click OK.
