Blue grass aquatics are selling green terrors with pictures of an adult and there are two different selections they both say green terror but one has white fins is the white silver saum or green terror619D5DB6-6DC3-408F-A897-4CC8DE9CD164.jpeg
 
The name Green Terror is a bit of a generic term , and can refer equally to two different species depending on where you live .
Andinoacara rivulatus (AKA orangesaum), and Andinoacara stalsbergi(AKA silversaum)
There are also other Andinoacara species that could be called green terrors. because many in the genus look similar.
If you really are concerned about getting a certain species, use the scientific name, otherwise its a crapshoot
Below a Panamanian green terror, Andinoacara coerleopunctatus.

And Andinoacara are not alone in the semantic confusion, red terror is another, which can refer to either Mesoheros festae (below) from South America west of the Andes

Or below, video of Mayaheros uropthalmus, in Mexico.

Post about differences


 
A. rivulatus has a different pattern in the reflecting part of the sccales. It forms a net pattern like in the picture in the first post.
A. stalsbergi has a lot of reflecting dots on the base of the scales. So the pattern is the opposite of the A. rivulatus pattern.


Typical A. stalsbergi:
 
Definitely silver saum.
Once you see the difference between rivs and stals it’s easy to tell them apart.
