Algae Control • Black Beard Algae Specialist • Peaceful Community Fish
📋 The Siamese Algae Eater (Crossocheilus oblongus) is a hardworking freshwater fish prized for its ability to consume even the toughest forms of algae, including black beard algae (BBA). Its slender body, silver coloration, and bold black horizontal stripe make it easy to identify.
Unlike similar species such as the Flying Fox, true SAEs are peaceful community fish that do not develop aggressive territorial behavior. They are active swimmers and best kept in groups, where they will continuously graze surfaces and plants.
A favorite in planted aquariums, the Siamese Algae Eater is considered one of the best natural algae solutions available to aquarists.
