Depends on your conditions, some of these are warm water fish and some are cold water species.

I suspect you'll have to research each type of fish you are interested in and compile a nice list for everyone! :lol:

The 1st few spots I'd look to get started on species details like life cycle, would be FishBase and Wikipedia. Check out what they each have to say about Rainbow Trout:

FishBase: Oncorhynchus mykiss (Walbaum, 1792) Rainbow trout
Wikipedia: Rainbow trout

Be sure to look at the sources or references or notes at the end of each article that each will use to refer you to further details.

Then I'd do a general Google search: trout life cycle

There are many organizations that have a special interest in a given fish species. Find the appropriate ones and you might just find your information.

The Wild Trout Trust: Trout Lifecycle
Stream Explorers: Trout Life Cycle
The Encyclopedia of New Zealand: Rainbow trout life cycle

That's a great way to get a head-start learning about your fish, but obviously the experience one gets while raising a particular fish is invaluable. For many species you'll also find forums of hobbyists and professionals which will have volumes of valuable information (like our BYAP forum.) Breeders and fish hatcheries also can be a wealth of information about their products.

While certainly a large enough tank and sometimes of a certain shape can be important, the matter of life-and-death factor is the amount of bioload (fish) your filtration can handle while providing detoxified clean water for the fish environment. Choose the amount of fish based upon your ability to filter the fish waste out of the water.
