Hi Cam. I found this here.... http://www.fishpondinfo.com/sae.htm
Siamese Algae Eater or SAE:
The true SAE has a jagged black horizontal stripe that goes all the way to the tip of the tail. All of the SAE's fins are clear. The black and white and their contrast are more intense than with the other algae eaters below.
False Siamese Algae Eater or false SAE:
The false SAE if usually found in shipments of true SAE (or the other way around). Unlike the SAE, the black stripe ends at the beginning of the tail. Often, if one goes to buy SAE's in a US aquarium store, they may in fact be all or mostly false SAE's. False SAE's may have some red around the mouth and a yellow tint to the fins. My false SAE had some nice gold and red on the dorsal fin. Mine was sold as a flying fox.
Flying Fox:
Just like the true SAE, the flying fox has a black horizontal stripe that goes all the way to the tip of the tail. Unlike the SAE, the edges of the stripe are smooth and not zagged. The flying fox may have some rainbow-like coloring on the fins. It is more pretty than the other fish mentioned on this page. The black horizontal stripe extends to the end of the tail like the SAE but it is much stronger and broader.
Chinese Algae Eater or CAE:
The Chinese algae eater is Gyrinocheilus aymonieri. Unlike the SAE, false SAE, and flying fox, the CAE does not have a distinct black horizontal line. It is more mottled. The fish is more brown than black and white. The tail fin lacks any striping. The CAE also does not have any barbels unlike the other three fish. If you go to the average pet store that carries fish and ask for a fish that eats algae, probably half the time, you would have a Chinese algae eater foisted upon you. While these fish are a delight like the above fish, they have only a low to moderate desire to eat any algae. If fish food is available, it will compromise most of their food intake. Also, as Chinese algae eaters grow older, the may become nasty to other algae eaters or even other fish in the tank. Some may try to latch onto fat-bodied fish. Sometimes, though some individuals get along well with their tankmates. There is a very common albino (or gold) CAE which may be sold even more often then the regular gray CAE. The CAE does not zip around as much as the SAE, false SAE, and flying fox. It tends to do more sucking. CAE's normally stay under 6 inches but have the ability to grow to almost twice that length.
