Fish are only one type of animal that eats algae. There are many algae-eating snails, shrimp and clams that can be interesting additions to your tank. Florida flagfish (Jordanella floridae) are great additions to the aquarium that has a brush or beard algae problem.
Perhaps the most popular freshwater algae eater fish are the sucker mouth catfish including Plecostomus (Plecos) and Otocinclus (Otos). While they do a good job on most forms of green and brown algae, especially algae on the tank walls, their mouths are not equipped with rasps that are strong enough to remove stuck on algae from tank walls.
