Siamese Algae Eaters come from Thailand, Laos, and Cambodia, and are a great addition to a community tank. They are often found grazing on hair algae or sitting perched on a piece of decor. While hair algae can be a large part of their diet, they will eat most prepared foods. They can be kept singly or in groups. While they can reach 6 inches, fish over 4 inches are not common.
