American Cichlids & New World Cichlids
Cichlids from the Americas include both North and South America, but the majority come from South America. South American Cichlids are considered aggressive, usually only due to the large size many of them attain as adults and the fact that they are carnivores. Most of these fish are not aggressive for the sake of being aggressive, they are aggressive because they eat small fish as a natural part of their diet. Pike cichlids are an exception to this, as they will often kill and do not always eat what they kill.
