green terros has black stripes?

When they are 1" long like most you see in stores they look almost the same. The only difference I see is green terrors have color on the fringe of their top and tail fin, acaras have no color on the tail fin. Maybe someone else can give you more tips.
 
why no acara? acara good...

green terrors and acaras are virtually identical when juviniles. however, green terrors, as stated before, have a distinct colorful fringe on the edge of their tail.
