Siamese algae eaters (Crossocheilus siamensis or crossocheilus oblongus) are freshwater dwellers that are members of the carp family of fish species termed Cyprinidae.

This tropical fish species is naturally found in the mainland of Southeast Asia in places like Thailand, and are bottom dwellers. They can be found in the Malay Peninsula and in the basins of Mekong and Chao Phraya.

As their descriptive name implies, Siamese algae eaters (or “sae” for short) feed on naturally growing algae found in their native habitats. For just this reason alone, these peaceful fish are terrific for keeping fast-growing algae from taking over an aquarium space over time.

While many fish experts recommend a little algae growth to maintain the proper food and ecosystem balance inside your tank, too much of it can be detrimental to the fish and other water creatures living there.

Adding Siamese algae eaters to an aquarium helps to control types of algae growth and maintain good aquarium health that is essential for the well-being of each occupant living inside of the tank. This also prevents cloudy aquarium water (which never looks good).
