can you please name the site in which i can get informtion about them

How much experience do you have? and bear in mind its all very well breeding fish, but please consider what you are going to do with a potentially large number of fry. Pet stores will very very rarely take home bred fish, and definitely won't buy them.

If you're a beginner (and assuming there's nothing else in the tank) stick with livebearers, there's no worrying about egg care that way. The humble Guppy or Platy or Endlers Livebearers.

If you're more experienced in fish care and want more of a challenge you could try one of these:
Bristlenose plecos
Corydoras
Neolamprogus dwarf shelldweller cichlids
Honey, Sparkling or Chocolate Gouramis
Wild-type mouthbrooding bettas
These fish will need more specialised care, and specific water conditions, in order to breed.
