Sicyopus is a genus of small gobies. Most are native to fast-flowing streams and rivers in Southeast Asia and Melanesia, but S. zosterophorus also occurs in China, Japan and Palau, S. nigriradiatus is restricted to Pohnpei, S. jonklaasi is restricted to Sri Lanka, and S. lord is restricted to Madagascar.
There are currently 10 recognized species in this genus:
Stiphodon is a genus of freshwater gobies. They inhabit swift, clear streams close to the sea and are found in large parts of Asia and Oceania. Many of the 36 currently recognized species have extremely restricted distributions on single islands or even single streams. These are small gobies with bodies squarish in cross section. A female of Stiphodon multisquamus with a standard length of 60.4mm is the largest Stiphodon individual on record.
Schismatogobius is a genus of fish in the subfamily Gobionellinae. They are native to southern and eastern Asia, Australia and the Pacific Islands. Adults dwell in freshwater habitat such as streams and rivers, where they live along the sand and gravel substrates.
Rhinogobius is a genus of primarily freshwater gobies native to tropical and temperate parts of eastern Asia. Most are small, streamlined in shape, and often sexually dimorphic. Few are of commercial importance, but R. duospilus is fairly widely traded as an aquarium fish.
Nemacheilus is a genus of stone loaches native to Asia.
Acentrogobius is a genus of gobies native to marine, fresh and brackish waters of the coasts of the Indian Ocean and the western Pacific Ocean.
Lentipes is a genus of gobies native to fresh, marine and brackish waters of the Malay Archipelago and islands in the Pacific. Its species are typically from fast-flowing streams and some are anadromous.
Mugilogobius is a genus of fish in the family Gobiidae. They are found in fresh, brackish and marine water of the Indo-Pacific region. Several of the freshwater species have highly restricted distributions.
Oryzias is a genus of ricefishes native to fresh and brackish water in east and south Asia. Some species are widespread and the Japanese rice fish is commonly used in science as a model organism, while others have very small ranges and are threatened. They are small, up to 8 cm (3.1 in) long, and most are relatively plain in colour.
Oxyeleotris is a genus of sleeper gobies mostly restricted to Australia and New Guinea, though some are found in Southeast Asia.
Sicyopterus is a genus of gobies native fresh waters from Madagascar to the Pacific islands.
Telmatherina is a genus of sailfin silversides endemic to the Indonesian island of Sulawesi. They are restricted to the Malili Lake system, consisting of the large Matano and Towuti, and the small Lontoa (Wawantoa), Mahalona and Masapi. They are also found in rivers and streams that are part of this lake system.
The Rhyacichthyidae or loach gobies are a small family of perciform fish in two genera. The three species all inhabit rivers and streams, often with fast flow. R. aspro is widespread in Western Pacific region, but the two remaining species are restricted to New Caledonia and Vanuatu. Little is known about their breeding behavior, but the eggs or larvae float down into the sea where the young grow up, only to later return to the adult river and stream habitat. They are fairly small fish, no more than 25 cm (10 in) in standard length.
Pseudogobiopsis is a genus of fish in the goby family, Gobiidae. They are native to fresh and brackish waters of southern and southeastern Asia. The genus is mainly distinguished by the number and arrangement of fin rays and spines, headpores, and sensory papillae, the large mouths of the males, a fleshy or bony flange on the pectoral girdle, and the shape of the genital papilla.
The Gobionellinae are a subfamily of fish which was formerly classified in the family Gobiidae, the gobies, but the 5th Edition of Fishes of the World classifies the subfamily as part of the family Oxudercidae. Members of Gobionellinae mostly inhabit estuarine and freshwater habitats; the main exception is the genus Gnatholepis, which live with corals in marine environments. The subfamily is distributed in tropical and temperate regions around the world with the exception of the northeastern Atlantic Ocean, the Mediterranean Sea, and the Ponto-Caspian region. It includes around 370 species and 55 genera: Wikipedia articles about genera list about 389 species.
Osteochilus is a genus of cyprinid fishes mainly found in Southeast Asia with a few extending into adjacent parts of China. Additionally, two species are endemic to the Western Ghats in India.
The Sicydiinae are a small subfamily of freshwater gobies, with only nine genera. They are usually found in fast-moving mountain streams in tropical islands. They are characterized by highly developed rounded suction discs and an amphidromous lifecycle. Adult lengths range from 2 to 15 cm. Some species are popular in the aquarium trade. The genera included under Sicydiinae are:
Belobranchus is a small genus of Eleotrid sleeper gobies from south-east Asia, New Guinea and the western Pacific.
Smilosicyopus is a genus of gobies native to Asia and Oceania.
Sicyopterus squamosissimus is a species of fish in the goby family Oxudercidae. It is found off the islands of Sumatra and Java in Indonesia.
