The golden otocinclus is one of the smallest known suckermouth catfish, often called a 'dwarf oto'. Endemic to Southeast Brazil, this herbivorous, rheophilic, bottom-feeder only grows to around 4 cm (1.6 in) in length. The close relatives of this small fish are often used for the purpose of controlling algae in small home aquariums, under the name Otocinclus affinis. In reality, they belong to the species O. vittatus, O. vestitus and O. macrospilus and O. huaorani. The real M. affinis is not present in the aquarium hobby.
Batasio is a genus of catfish of the family Bagridae. These small fish are found in fast-flowing hillstreams throughout South and mainland Southeast Asia.
The name upside-down catfish is most commonly used by aquarists to refer to the mochokid catfish Synodontis nigriventris alternately known to ichthyologists as the blotched upside-down catfish or false upside-down catfish. However, a number of other fish may also be known by this name:
Mystus is a genus of fish in the family Bagridae native to Asia. Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages.
The silver cyprinid also known as the Lake Victoria sardine, mukene, and omena, dagaa (Swahili) is a species of pelagic, freshwater ray-finned fish in the carp family, Cyprinidae from East Africa. It is the only member of the genus Rastrineobola.
The African butter catfish is a species of fish in the family Schilbeidae. It is native to many major river systems in Africa. Other common names for the fish include butter fish, butter barbel, African glass catfish, lubangu, mystus catfish, silver barbel, and silver catfish. It was originally described as Silurus mystus by Carl Linnaeus in 1758.
Vikramshila Gangetic Dolphin Sanctuary is located in Bhagalpur District of Bihar, India. The sanctuary is a 60 kilometers stretch of the Ganges River from Sultanganj to Kahalgaon in Bhagalpur district. notified as Vikramshila Gangetic Dolphin Sanctuary in 1991, it is the protected area for the endangered Gangetic dolphins in Asia. Once found in abundance, only a few hundred remain, of which half are found here.
Mystus leucophasis is an Asian species of upside-down catfish belonging to the family Bagridae. It is known for its unusual behaviour, as it primarily swims in an inverted position and never upright.
Hydrocynus vittatus, the African tigerfish, tiervis or ngwesh is a predatory freshwater fish distributed throughout much of Africa. This fish is generally a piscivore but it has been observed leaping out of the water and catching barn swallows in flight.
Hemibagrus punctatus, or Nilgiri mystus, is a species of fish in the family Bagridae. It was first described by Jerdon in 1849. It is endemic to east-flowing rivers in the Western Ghats of India. Of these, the species is likely only found in the Kaveri River; records from the Krishna River may actually be of H. maydelli. However, one record from the west-flowing Bharatappuzha River has been tentatively assigned to this species. The last record of this species was in 1998, and it may have experienced a population decline of nearly 100%; thus, IUCN categorizes the species as critically endangered. It is threatened by habitat degradation by excess siltation, excess fishing, and dam construction. However, based on several specimens caught by fishermen between 2011 and 2012 that likely belong to this species, as well as testimonies from local fishers, moderate populations of this species may still be extant in the region.
Mystus cavasius, the Gangetic mystus, is a species of catfish of the family Bagridae.
Mystus gulio, the Long Whiskers Catfish, is a species of catfish of the family Bagridae. The generic name is probably derived from the Latin "mystax", meaning "moustache", due to the long barbels.
Mystus keletius, is a species of catfish of the family Bagridae. It is native to India and Sri Lanka.
Mystus ankutta, also known as the Sri Lanka dwarf catfish or yellow dwarf catfish, is a species of catfish of the family Bagridae that is endemic to Sri Lanka. In the wild it is found in freshwater bodies from Kelani river to Nilwala river in Sri Lanka.
Mystus falcarius is a species of catfish endemic to India and Myanmar and is known only from Irrawaddy River, Great Tenasserim River and Chindwin River. The exact population is not known but is thought to be abundant and no exact threats are known thus Least Concern by the IUCN; it is fished for food.
Mystus bocourti is a species of catfish endemic to Cambodia, Laos, Thailand and Vietnam, known only from Chao Phraya River and Mekong River. It was formerly listed as Heterobagrus bocourti until the genus Heterobagrus became Mystus. It is demersal and potamodromus and occurs in medium to large rivers. The fish considered rare and declining throughout its range and is threatened by pollution, present and future dams and water extraction for agriculture and human settlements. Considering this and no present conservation measures, the fish is listed as Vulnerable.
Mystus albolineatus is a species of catfish endemic to Cambodia, Thailand and Vietnam, known from Chao Phraya River, Bang Pakong River, Mekong River and Tonlé Sap. It is found in flowing and standing waters especially near submerged woody vegetation; it feeds on zooplankton, fishes and insect larvae such as chironomidae. It spawns before or during the rainy season and the young were first caught in July and August. It occurs in both the market and aquarium trade and is fished with seines, gillnets and traps. It is not considered threatened thus listed Least Concern, however, further research about this fish is needed.
Mystus atrifasciatus is a species of catfish endemic to Cambodia, Laos, Thailand and Vietnam, known from Mekong River, Chao Phraya River and Mae Klong River and was described from Phitsanulok, Thailand. It inhabits rivers, streams and reservoirs and moves to floodplains when the water level increases and can also be found near submerged woody vegetation. It feeds on crustaceans and zooplankton along with some algae and fish scales. It is commonly fished and marketed and is also found in the aquarium trade. It may be threatened by pollution and overfishing and more research is needed about the species.
Raosentis is a genus of Acanthocephala that parasitize the intestine of fish.
