Chinese Algae Eater (CAE) Gyrinocheilus aymonieri 4cm

The Chinese Algae Eater (Gyrinocheilus aymonieri) is a popular and hardworking algae-grazing fish, well known for its ability to clean algae from glass, rocks, and décor in the aquarium. Young CAEs are excellent algae consumers and are widely used as a natural algae control solution in community tanks. As they mature, they develop a more robust, golden-olive body with a distinctive sucker mouth adapted for rasping algae from surfaces. A practical and interesting fish for medium to large aquariums.
