The Golden Algae Eater, a variant of the Chinese Algae Eater (Gyrinocheilus aymonieri), is a golden-yellow, sucker-mouthed freshwater aquarium fish primarily known for its ability to control algae growth on tank surfaces. This hardy, bottom-dwelling fish is active and can become territorial with age, requiring adequate hiding spots and a spacious, well-filtered tank. Its diet includes algae, algae wafers, and sinking pellets, but it also needs occasional vegetable-based foods.
