I discovered Fish Tycoon yesterday and I am hooked! I downloaded my game from AOL and have been playing ever since.

I have some strategy questions. I started off with my orginial eggs and purchased another set of common fish eggs.

Let's say I stumbled upon a Topazfined Gemfish (so it's not a spoiler) and was able to successfully breed them and sell them for $60 each. Is my best strategy to sell off all other fish, breed and sell that one to buy a second tank and research the environment? Or can you flood the market and not be able to sell one type of fish for long?

When breeding fish, if the offspring die at 5 years old, is it a safe assumption that breeding those fish at your current level is not a good idea?

Will someone come do my laundry and cook our meals so I can play more?
