andinoacara rivulatus

That's the problem with common names. "True green terror" is constantly debated. The rivulatus is what most people think of when some one says GT, but it's also called a "gold saum".
 
Andinoacara stalsbergi was also known as a green terror.Andinoacara rivulatus was traded and also called a green terror.They were also referred to as Saum as a distinguishable name for the gold and silver variety.
If memory serves me correct andinoacara stalsbergi was the original "green terror ".Not so common in the hobby as rivulatus and so rivulatus took over as the most well known fish to be named green terror.
 
Gold saums are rivulatus. Also, somehow 'original green terror' has gotten mixed up for a lot of people and it's not what they think. IMO the confusion comes from questions among experts before recent years over which was the true rivulatus, the original fish being described in 1860. In some older books and articles what is pictured as the true rivulatus is what is now stalsbergi, a rare fish in the hobby before recently, and gold saums were thought to likely be a another fish. From this some got the idea stalsbergi were the original green terror and this has proliferated on forums. BUT-- it turns out gold saums are rivulatus, hence a morph of the fish originally described in 1860, and stalsbergi are another fish-- so on this score stalsbergi is not the original green terror.

Hobby-wise, gold saums entered the hobby in the 1970s, what is now stalsbergi (what some thought was true rivulatus) was only known in a few photographs at the time. A 1982 German article called what is now stalsbergi "The Green Terror that Isn't", in other words a false green terror, opposite the notion most people now have. In reality, true and false green terror or original green terror is kind of a moot point, but if you wanted to get technical over the history in the hobby, gold and white edged rivulatus would be the original fish called green terrors when they entered the hobby-- so, on this score stalsbergi are not the original green terrors.

Rivulatus are fish from Ecuador, whether gold edged or white edged, Stalsbergi are from Peru. It can be confusing, got into a big forum argument once because while I had it right in my head I didn't explain it well and then I used a confusing article as my reference, so they seemed to think I was saying the white edged rivulatus was stalsbergi. If you want to read an expert's account of the history for yourself, this is now my go to article.

...So, if you want stalsbergi because it's the rarer fish in the hobby that's one thing. But, while some people now think so, it's not the original green terror.
 
..Oh, and by the way, while the 2010 Wayne Leibel article says Alf Stalsberg doesn't agree with gold saums being rivulatus, don't let that throw you. Alf has since backed off of that. From his Andinoacara web page:
I did not agree with this and did more work with these fishes, and the more I learned about these fish I was certain that this fish we called "Aequidens" sp. Goldsaum was not Andinoacara (Aequidens) rivulatus. But I had to change my mind later.
Of course, all things cichlid are subject to change, makes keeping it all straight an interesting proposition. :D
 
Should qualify something. Rereading the article, it says some stalsbergi were collected and distributed not all that long after gold saums entered the hobby, so to most people at the time what is now stalsbergi were known only in photos.

Years ago I had gold (and white) edged rivulatus at the same time I had books showing what is now stalsbergi as the true rivulatus, except we now know they weren't-- so back then I thought I didn't have true rivulatus, except I did. Crazy hobby. :D
