Other than a fringe around the edge of the fins which can be gold or white, (Saum means fringe in german i believe) I don't see how these aren't both green terrors. Perhaps someone more educated than me can illuminate me on this.
 
The "Aequides" group keeps changing, being split into smaller and smaller groups, there is some interesting information on the silver and gold saum here..

Sometimes it also depends on catch location, fish that get banded under "blue acara" could be not genuine pulcher, but only an expert can tell sometimes.
 
Awesome article! Still seems like more of a subspecies thing to me though. I have a Midas and although it can breed with a red devil they're definatly not the same fish. Same thing for my Convict and Jack Dempsey (luckily they hate each other).
My guppy and endlers....hmmm I don't know they look like the same species to me but I still see more differences between Poecilia reticulata and wingei than Silver and Gold Terrors.
 
The silver/white saum has been now named as Andioacara stalsberg  and the gold remains as Andioacara rivulatus (formerly aequidens), they are the same species, just now finally split into two due to the colouration differences.
 
Sometimes I think these scientist hooligans just get drunk together and cause academic mischief.
 
Lol I know what you mean sometimes it does get confusing best one for me is Aquedens Diadema and Aquedens sp.Jenna Herra - Jenna Herra is slightly more common in the trade but its not recognised as Diadema as they have different coloured ventral fins...
 
Anyway back to Green Terrors - there are even more fish traded as Green Terrors than just the two Star mentioned I think its like 4 or 5 different species. The reason they are divided so much is not often just external appearance - externally it comes down to rows of scales, number of spines in the fins, eye location etc. But they are often determined by internal functions like organ size and placement etc.

That's not entirely correct, there is two common types of Rivulatus, one with a gold seam and one with a white, stalsbergi which is known as the true terror also has a white seam but it differs from the white seamed rivulatus in most notably scale pattern - the colourful part is the centre of the scale with a dark outline where as Rivulatus is the opposite with a dark scale and a colourful outline. Size- they stay smaller and tend to be a bit more elongated and aggression- Stalsbergi tend to live upto the name terror.

The Alf Stalsbergi article you posted is really good info. He's the man to turn too if you have any Andinoacara or Aequidens queries.
