Species often confused with {name}
Flying Fox
Epalzeorhynchos kalopterus
Key differences: The Flying Fox has a similar black lateral stripe, but it is typically smoother-edged and does not extend into the caudal fin. Crucially, Flying Foxes have prominent red/orange coloration in their dorsal, anal, and caudal fins, and possess two pairs of barbels (vs. one inconspicuous pair in SAEs).
False Siamese Algae Eater
Garra cambodgiensis (often misidentified as Crossocheilus siamensis)
Key differences: The False SAE has a less distinct black stripe that often fades towards the caudal fin and does not extend into it. Their fins are also clear, but their body shape can be slightly more robust, and they tend to be less effective at eating certain types of algae. They also have a more pronounced downturned mouth.
Red-tailed Black Shark
Epalzeorhynchos bicolor
Key differences: While also a cyprinid with a similar body shape, the Red-tailed Black Shark is entirely black with a vibrant red caudal fin. Its temperament is also significantly more aggressive and territorial than the SAE.
