Comments: This is the ultimate red/brush algae eater. This is also the ultimate misidentified fish. This fish is not commonly found in North American pet stores, and is more common in Europe. It is in high demand in the states due to its algae appetite, and there are some that will pass off imitations on the novice fish keeper. Want the real deal? First, look at the name. This fish is called the “Siamese Algae Eater” (SAE), and “Siamese Flying Fox”. I bought it as a “True Flying Fox”. Be wary of the term “Flying Fox”, however, – there is another, similar looking barb also called the “Flying Fox”. Next, look at the coloration on the fish. All SAEs and their imitations have a black stripe running down the sides of the fish. On the SAE, this line goes all the way to the fork in the tail fin. Also, many imitation SAEs will have black on their anal and pectoral fins. The true SAE does not. See the pictures for better reference. It is a common warning that these fish are jumpers, and I can confirm from personal experience that is true. Only keep these guys in an aquarium with a cover.
