| Comments: |
Two colour varieties of the "Green Terror" had long been recognised in the aquarium trade, one with white edges on the tail
and dorsal fins (often known as the Silver or White Saum), and one with yellow/orange edges (often known as the Gold Saum).
The Gold Saum "Green Terror" is thought to be the true Andinoacara rivulatus, though some believe it may be a closely related species, Aequidens aequinoctalis.
The Silver Saum or White Saum "Green Terror" has now been described as Andinoacara stalsbergi.
