Part of the Isola series byLast Day of Work ↗(HTTP only)
Fish Tycoon is a virtual fish store where you breed and care for exotic fish, selling them to keep the business alive. The real goal is discovering the Seven Magic Fish of Isola — rare species tied to the island's mythology, each one requiring the right breeding combination to unlock.
⏱ The game ticks forward in real time, even while closed. A Cheat Engine speedhack is a common way to skip the waiting. Changing your system clock forward works too.
