What does one do after they have won fish tycoon? It's already getting old. I was obsessed, I won...and now I'm bored. What next? Any suggestions?

Set yourself a challenge and start over.

My current challenge is to find all 441 fish without trashing a single fish.

I think next I'll try doing it without using any growth hormone.

You could aslo try the game on high difficulties (if you used easy last time). Adds another depth of challenge.

What is different about it being harder?

From what I've noticed.... the fish need to be watched muchmore carefully. They get sick easier and spread it faster. Hungrier more often.

And, although this is proabably just coincidence, I never seem to get the fish I need from eggs!
