Explore our collection of freshwater algae eaters selected to support a cleaner, healthier, and more balanced aquarium. This collection includes hardworking fish and invertebrates that naturally graze on soft algae, diatoms, biofilm, leftover food, and other organic material found throughout established freshwater aquariums.
Choose from Otocinclus Catfish, plecos, Siamese algae eaters, freshwater snails, shrimp, and other helpful members of the aquarium cleanup crew. Each species targets different types of algae and has its own requirements for aquarium size, diet, water conditions, and compatible tank mates.
Algae eaters should be considered part of a complete aquarium maintenance routine rather than a replacement for water changes, filtration, and regular cleaning. Natural algae may not provide a complete diet, so supplemental algae wafers, spirulina-based foods, vegetables, or species-appropriate prepared foods may still be required.
Review each individual listing before purchasing to ensure the animal is appropriate for your aquarium. Some algae eaters remain small and peaceful, while others can grow large or become territorial as they mature.
