Central American does have the more aggressive cichlids. BTW...Cichla ocellaris is a pbass..haha..and its SA...

. There are some seriously aggressive cichlids in SA though, Crenicichla, festae, umbie just to name a few. For the predatory fish though, SA have a slight advantage in #'s...got Crenicichla, Cichla, Caquetaia, and Astronatus just to name a few families...
