Gyrinocheilus aymonieri |
The true algae eaters are a single-genus family (Gyrinocheilidae, Gyrinocheilus) of small Southeast Asian cypriniform fish that live in fast-flowing freshwater, hold on to fixed objects using a sucker-like mouth, and feed primarily on algae.
The Chinese algae eater, Gyrinocheilus aymonieri, is sometimes kept in aquaria to control algae. It can range up to 28 cm in length, but aquarium residents tend to be under 10 cm. It has a reputation for becoming increasingly jealous of its territory as it matures.
Two other Gyrinocheilus species, rarely seen in the aquarium trade, are the spotted algae eater and the Borneo algae eater.
[edit] Other algae eaters
The Siamese algae eater, Crossocheilus siamensis, is a more gregarious and tolerant cyprinid that ranges up to 15 cm. It is the only fish that will also graze on 'Black Brush Algae' ( freshwater Rhodophyta, or Red algae), but even so will eat anything else in preference.
American-flag fish, Jordanella floridae, are also dependable algae eating fish. Many loricariid catfish of South America such as Otocinclus and Plecostomus species constantly graze algae and biofilm, although 'Plecos' eat much less frequently as they near adulthood.
Another excellent group of algae eaters are freshwater shrimp. One shrimp well known for its ability to clean an aquarium is the Amano Shrimp.
Additionally bristlenose catfish, are popular, efficient, & often used.
In the home aquarium, the algae eater makes a good tank mate. It not only keeps an aquarium free of algae, but it also leaves other fish alone. It is very timid and shy. It rarely swims to the surface as it likes to be on the bottom of the tank. It is very hardy and can survive in semi-dirty water, plus a wide range of temperatures, 60 - 90F.
