If you want to breed clown fish, the first thing you should do is get all the info you can on line or read all the books you can get your hands on. The book he recomended is a very good book and it is easy to understand. This forum alone is full of good knowledge and people full of good info. Do all the research you can on the fish that you plan to breed and also how to rear the fry once they do breed. That will be the real challenge! by the way, the so called f. perc is A. ocellaris, and yes there is a black strain of ocellaris from the Darwin area of Australia. I wish you the best of luck!!!
