Trichogaster is a genus of gouramis native to South Asia from Pakistan to Myanmar. It is the only genus in the monotypic subfamily Trichogastrinae as set out in the 5th Edition of Fishes of the World, although that book states that there are two genera, the other being Colisa which is treated as a synonym of Trichogaster by Fishbase and the Catalog of Fishes. Fishbase also places the genus in the Luciocephalinae. Species of this genus are very popular in the aquarium trade.
Tonguefishes are flatfish in the family Cynoglossidae. They are distinguished by the presence of a long hook on the snout overhanging the mouth, and the absence of pectoral fins. Their eyes are both on the left side of their bodies, which also lack a pelvic fin. This family has three genera with a total of more than 140 species. The largest reaches a length of 66 cm (26 in), though most species only reach half that size or less. They are found in tropical and subtropical oceans, mainly in shallow waters and estuaries, though some species are found in deep sea floors, and even a few in rivers.
Vieja melanurus, the quetzal cichlid, redhead cichlid or firehead cichlid, is a species of cichlid that is native to the Lake Petén system, the Grijalva–Usumacinta River basin and other Atlantic river drainages in southern Mexico, Belize and Guatemala, with introduced populations in a few other countries. It typically inhabits slow-moving or standing waters such as rivers, lakes and lagoons; although primarily a freshwater fish, it may occur in slightly brackish habitats. It is popular in the aquarium trade, where often listed under the synonym V. synspila/synspilum. It is almost entirely herbivorous, but may also take small animal prey.
The Platycephalidae are a family of marine fish, most commonly referred to as flatheads. They are relatives of the popular lionfish, belonging to the order Scorpaeniformes.
Osteobrama is a genus of cyprinid fish found in southern Asia consisting of eight species. The name is derived from the Greek word osteon, meaning "bone", and the Old French word breme, a type of freshwater fish.
Gagata is a genus of sisorid catfishes native to Asia.
Cirrhilabrus ryukyuensis is a wrasse from the western Pacific Ocean from Indonesia, Malaysia and the Philippines north to Japan. It occasionally makes its way into the aquarium trade. It grows to a size of 15 cm in length. SOme authorities regard this taxon as a synonym of Cirrhilabrus cyanopleura, but Fishbase and the Catalog of Fishes treat it as a valid species. This species was called Cirrhilabrus lyukyuensis but this is treated as a misspelling.
Rita gogra is a species of bagrid catfish endemic to India where it is found in the rivers of the Deccan Plateau up to the Krishna River system. It is an inhabitant of large rivers. It grows to a total length of 26 cm and is commercially fished for human consumption.
Anadoras weddellii is a species of thorny catfish that is found in Argentina, Brazil, Bolivia and Paraguay. This species grows to a length of 15.0 centimetres (5.9 in) SL. The IUCN Red List considers Anadoras regani a junior synonym of Anadoras weddellii, but FishBase and the Catalog of Fishes regard it as valid.
The Sellal bleak is a species of ray-finned fish in the genus Alburnus. It can be found in the drainage basins of the Queiq River and the Tigris–Euphrates river system in Iran, Iraq, Syria and Turkey. A recent study has found that Alburnus mossulensis was probably a synonym of Alburnus sellal.
Nemacheilus triangularis is a species of stone loach endemic to the Western Ghats in southern Karnataka, Kerala, and Tamil Nadu, India. It is a fairly common species occurring in streams with gravel, cobbles and bedrock with some sand as the substrate. This fish grows to a length of 5.8 centimetres (2.3 in) SL and can be found in the aquarium trade.
Mesonoemacheilus petrubanarescui is a species of ray-finned fish from India. The specific name petrubanaescui honours the Romanian ichthyologist Petre Mihai Bănărescu. It grows to 3.5 cm (1.4 in) standard length. It is endemic to the Western Ghats and is known from only two locations, the Netravati River and Kabani River in Karnataka and Kerala. It is a little known species which is rare and may be threatened by habitat alteration, sand mining and pollution. It turns up occasionally in the aquarium trade where it is sold as the "dwarf loach".
Nemacheilus subfusca is a species of ray-finned fish from the family Nemacheilidae in the genus Nemacheilus which is found in Assam and China. It inhabits pebbly streams. N. subfusca was synonymised with Neomacheilus scaturigina which was described by Menon from the collection of Hamilton. It was, however, then treated as a valid species and sometimes placed in the genus Schistura.
The short-tassel weedfish is a species of clinid native to the Pacific Ocean waters around the Bass Strait and New Zealand. This species are known to feed on fishes and benthic crustaceans. It is the only species in its genus. Klunzinger's name, Clinus marmoratus, is a homonym and was preoccupied by Castelnau's Clinus marmoratus, rendering it invalid for this fish and this name is now considered to be a junior synonym of Cologrammus flavescens.
Bangana is a genus of fish in the family Cyprinidae, the carps and minnows. It is distributed across much of southern and eastern Asia. Species live mainly in the flowing waters of tropical and subtropical rivers.
Nemachilichthys shimogensis, the Shimoga loach, is a species of stone loach from the Western Ghats of Maharashtra and Karnataka. Although Fishbase treats it as a valid species some authorities state that N. shimogensis is the same species as, i.e. a synonym of, Nemacheilus rueppelli, which they then place as the only species in the genus Nemachilichthys.
Pseudocaranx is a genus of ray-finned fishes from the family Carangidae, the jacks, trevallies, scads, and pompanos. They occur in the western Atlantic Ocean and the Indo-Pacific.
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.
Plectorhinchinae, is one of two subfamilies of the family Haemulidae, some known colloquially as sweetlips. This subfamily is regarded as having an Old World origin.
The humpback mahseer is a species of freshwater ray-finned fish from the Indian endemic genus Hypselobarbus in the carp and minnow family Cyprinidae.
