Answer
Hi Soni,

What you need is a database to search with. Try this one:
http://fish.mongabay.com

Here's how to use this database. Type the common name of the fish you are seeking info on into Google.com. Use it to find the scientific name of the fish. For example, for a goldfish it is Carassius auratus. Go to the bottom of the page I linked to above, there will be a link entitled Search. It will take you to a new screen, in which you can type carassius auratus. A Google powered search of mongabay.com will occur, and the first link that appears is:
http://www.mongabay.com/fish/species/Carassius_auratus.html
That will give you a species profile, including sexing and breeding information. Try it! They have many species listed.

I hope that helps, take care!
