easiest freshwater fish to breed?

algae.
 
Since when is algae classified as a fish?:p: Time for bed.:)
 
any type of livebearer, danios, most cichlids (especially convicts.)
 
How easy are demasoinis???
 
Yah, livebearers. If you're wanting to raise your own feeders, guppies, endlers are a good way to go. Prolific, colorfull, easy to gut load...
