I don't normally like "opinion" type "what shall I get threads, because that's just what they are. You might like blondes, she might like brunettes, that kind of thing.
And it depends a lot whether its a display tank or not.
In my display tanks I don't like to mix continents, for a number of reasons.
First, they look goofy to me. If that doesn't matter to you...no sweat
Water parameters and aggression levels are a more important factor.
I find north American cichlids much more aggressive than S Americans (IMO north america starts in Panama going north, S America runs from Colombia south. "Most" S American cichlids are not able to match aggression of their northern cousins with a few exceptions.
Central America waters are generally hard and alkaline.
A large section of South American water is soft and has tannins that act anti bacterial, so S American immunity to certain diseases is somewhat different, than their hard water cousins.
Also much of southern S America is temperate compared to the tropical north.
I don't keep Uruguayans with fish from northern Brazil, the distance between is more than Toronto Miami, and temps and seasonal changes can be quite different
And although a 180 gal is a decent size tank, I found I had to move cichlids like pearsei, and bocourti to 300 gallon tanks because within 2 years they outgrew my 100+ gallon tanks.
And although both are some of my favorite, both species are also plant decimators being heavily vegetarian, mine ate 3 ft papyrus down to nubs.
But there I go, blathering again
