breeding is no easy task with most fish and simply luck most times as many are not even bred at home purposely in most cases sometimes a fish just goes by instinct and breeds by itself, the best thing to do is buy books and look at websites (as many as possible) and find out about your fishes breeding habits then go by that as its a little difficult for me to know the habits of every fish lol hope I helped a little bit though.
