Hi firewire, and welcome to RC.
You have started a thread on the The Fish Breeding Forum, asking about fish breeding in general, as though it can be answered in one thread. I am afraid your question is too broad for anyone to respond to.
What are you interested in breeding?
If you don't know yet, that's OK, just keep reading. Individual threads are for asking questions and sharing knowledge and observations. There is a wealth of information here, and all you have to do is read it. Searches are also helpful if there is something specific you are after. Browse around, and read the threads at the beginning of the forum. They will answer many of your questions.
Good luck!
