Nope, they aren't the same thing, but it can get to be a confusing subject.I think the flying foxes must be the Chinese Algae Eaters which are not very nice fish when they get older.
They sure are lazy! I asked the guy from the LFS if they're similiar to Oto's as far as eating algae, and he said yes, lying bas****..Ha, those guys are lazy algae eaters. In fact, they don't do anything for the tank but eat whats left on the ground. SAE's are much better, but also get lazy as they get older.
