Crossocheilus siamensis also called Siamensis Algae Eaters (SAE), originated from Kalimantan (Borneo) and Sumatra. Although the color of the body was not spectacular, but these algae-eating fish found in many aquarium aquascaping because he is an avid algae-eating fish.
The Siamese algae eater (Epalzeorhynchos siamensis or Crossocheilus siamensis) has a black horizontal stripe extending from opercle to tail. The genuine Epalzeorhynchos siamensis alias Crossocheilus siamensis without maxillary barbels and with deeply fringed V-shaped upper lip is rarely encountered in the aquarium trade.
Closely related is the Red-algae eater Crossocheilus langei, a species that is widely sold as the Siamese algae eater. It has a bright brownish elongate body with a slightly flat belly. It has a prominent brown-black horizontal stripe extending from nose to tail.
This fish may grow up to the length of 16 centimeters. It possesses small maxillary barbels and an unfringed shallowly arcuate upper lip.
Two other similar species are traded as Siamensis algae eaters, namely Crossocheilus atrilimes, a species that likes to eat Java moss rather than red algae, and an undescribed species of Crossocheilus.
