I just picked up what I'm hoping are 4 SAEs last night. They had "Indonesian flying foxes" and Siamese flying foxes". The Indos looked like standard FFs, darker back, dark stripe through the tail. The Siamese ones, which I bought (only about 1.5") have a much lighter back, and the stripe goes all the way through the tail but is much lighter on the caudal fin than on the body. Fingers crossed, I put them in my planted 10gal right now so hopefully they'll learn to eat hair algae quick, there's a ton of it.
