Are you someone or do you know someone who breeds freshwater fish?

Something I have never intentionally done it breed freshwater fish. I know that there are some people who like to breed fish and it is something that they do regularly but I can imagine that would take a lot of time and you would need to know exactly what you were doing and how to treat the water and such ready for when the babies were born.

Are you someone who likes to breed freshwater fish? Would you consider it if you don't already?
