2000's games #2 - Fish Tycoon (2004)

I don't know at all when i found it, most likely in the early 2010's but it is actually a classic game from the early/mid 00's (2004)!  It is the prequel of Plant Tycoon.

The lore in short: The nature on an exotic island called Isola got destroyed by pollution and many species became extinct, you have to recreate them by breeding fishes, specifically, you have to recreate the 7 special magic fishes of Isola, each have a special effect to your other fishes like one do a health buff and your pets won't get diseases then. While you breed the fishes which worth more, you can upgrade the equipment, buy a new tank, decorations, higher level fish eggs. You can earn money by selling fishes that you don't need or you can hack the game with cheat engine. The game going on in real time so you have to stop the time inside the options when you go away for longer periods of time, otherwise your fishes will die or get sick, but if you are around your computer you can also speed the time up (just don't forget to turn it off later)

Oh and i have good news for ya, the game is officially free so you don't need to look for a torrent!

(to have fishes with the fins which belong to the species - just4fun)

Note: There is a new version too but it is not the classic.
