Whether or not you have an algae problem in your tank, Otocinclus Catfish (Otocinclus macrospilus) make a great addition to any aquarium community. Also known as Otto Cats, otos, or dwarf suckermouth catfish, these fish use their sucker-mouths to attack algae on the aquarium glass, plants, and decorations. In fact, they are widely considered one of the best algae-eating fish in the world, and groups of them form quite the cleanup crew with their voracious appetite for algae. They come from fast-flowing rivers in South America, so they do best in aquariums with strong currents (which can be achieved with good water filters or powerheads), good filtration, and plenty of aeration.
