MFK is the only place I have heard people debate that the rivulatus is the true green terror even after most people have just been told stalsbergi was. Anywhere else everyone likes to automatically correct rivulatus name callers that the stalsbergi is true though a lot of them have never kept either. Alf Stalsberg is active of Facebook and one the biggest authorities I know of that refers to the true as stalsbergi, though I don't know his explanation behind it.
The plot thickens.
This isn't the only forum where I've seen this debated, but let me make clear what my primary point is and has been: It's that insisting on a 'false' and 'true' green terror is, as I said above, artificial. The real question originally was which one is rivulatus. I've seen Alf, Wayne Leibel and others call Andionacara the 'green terror group'.
I've spent a lot of time on Alf's web site. There he says: "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." Issue? Which is rivulatus, not which is green terror.
But-- now I see Alf has another web site on which he makes a point of saying rivulatus is not a green terror. There he says stalsbergi was the first fish imported to Germany and called a green terror, the Leibel article says rivulatus was the first fish imported (to the US) and called green terror, and a German writer called stalsbergi "the green terror that isn't".
Apparently the history depends on which expert you listen to, or maybe the country where you (or they) live. Beyond this, according to a couple of the official taxonomic registries I've looked at, some countries have other names for the fish and don't call them green terrors at all. So, maybe you can split hairs and say in the US rivulatus was the original green terror and in Denmark stalsbergi is considered the original green terror.
So, what? Apparently, if you want to get technical, rivulatus is historically the original US green terror and other countries say it's stalsbergi. Or if you've been reading Wayne Leibel rivulatus is the first and if you read Stalsberg it's stalsbergi.
That's a lot of splitting hairs. When someone simply calls their stalsbergi a green terror I haven't said anything. When someone calls their rivulatus a green terror I haven't said anything. It's only when someone makes a point of "true" vs. "false" green terror that I've interjected to point out a reference with the history. You can see that in this thread, not a peep out of me to the original poster for calling his stalsbergi a green terror, nothing until the "true" and "false" thing was brought up.
Either way, I still say "true" and "false" is artificial, artificial bragging rights. The only question of substance had been which is rivulatus and that's been settled.
