oops...hit post to early....
.....most impressive clownfish displays I have seen was at the aquarium in Coney Island New York. I was recently there and they had a tank filled with many species of clowns and they were all HUGE!!! Of course many of them had some torn fins and what not, but you know what they were all breeding..right down to the loan pair of black saddlebacks. I have found this tank to be a common theme in every public aquarium I have visited. So all I did was do what they did and put my own sort of spin on it to try and replicate nature and you know what? It worked. I would imagine it would work with every Amphiprion species, the important thing being the order of introduction. I imagine that in nature that groups of adolesenct clowns do not simaltaneoulsly show up at a given unoccupied anemone, so don't do it that way in your tank. Put several in of staggering sizes, and no previously established pair bonds. Finally I do think that in this instance an anemone is instumental in the success of a clown family. The tank should be structured in such a manner that allows the female to have the prime lookout posiion, the male his little egg patch and the juvies their section of anemone. Just look at all the pics you can find of wild clowns. Also as I mentioned before keep them well fed best of luck to you. In the future I would like to do this again but eventually remove for example the female so that I can watch the entire group transgress the gender ladder. I didnt do this before as I became attached to the female and didn't have the heart to disrupt the happy family Anyway best of luvk to you.
