Feeding a lot helps lessen aggression w/ some fish, but w/ clowns it has more to do w/ their territorial nature and heiarchy IMO, but it could help some.
I agree w/ Shred, number should be based on bioload capability primarily, and what appeals to you I guess.
I like seeing others do this some, when it's done properly, but for me personally, it's already been done, and I love the variety of fish I keep, and I'm more drawn to my special pair of clowns I love so much, rather than a mass of clowns, but that's just me, to each their own.
