While this is true I have come to the conclusion that there are subtle differences between the saums and a true green terror:
Green Terror - Shiny scales with a dark border, top fin has silver tip
Silver Saum - Dark scales with a shiny border, top fin has silver tip
Gold Saum - Dark scales with a shiny border, top fin has a red tip
Blue Acara - Looks similar to the 3 above but does't match the descriptions for the 3 above.
Going by the descriptions, I think the picture is a silver saum. If it was true green terror the scales would be shiny with dark border, not the other way around.
