There are about 160 specie of Central American species alone.
Unless an aquarist has kept them all, how would one know?

Of the only 100 species I have kept, I believe that pound for pound Neetroplus nematoplus is the most aggressive, but that leaves at least 60 species unaccounted for.

In South America alone....
There are at least 75 species of Pike Cichlids!

The question is at best, unanswerable

That's why I said "personal opinions and experiences". I'm sorry if I didn't worded it well enough.

I have kept all the fish mentioned above (south and central americans)
And haven't found any of them very aggressive if kept in appropriate sized tanks.
Because it's all about territoriality , and prper space.

Some of the problems cichlid keepers enounter with aggression is of there own making, by not rrealizing how cichlids prefer to live in nature.

Firemouth cichlids ( those of the genus Thorichthys) are often thought of as aggressiove, but in reality if kept in shoals of their own kind (the way they live in nature) without other cichlids they are mostly benign.
But when kept as single indiviuals or pairs, they become A-typiaclly hyper aggressive, because that is anti- to the way they have evolved to exist in nature.
In nature they live in shoals or packs of at least 6 to 8, where they sift sand and silt, in comfortable safety in numbers, and are seldom found in pH levels of less than 7.5, preferably closer to 8..
And they live in large open areas, so puttig a shoal of them in 4 or 5 ft tanks is too confining, so to me a shoal in a 6 ft tank of at least 125 gallons, would be minimal tank siize.

Tis also goes for other similar sand sifters such as Cribroheros, ad the South America's of the tribe Geophaginii.
