Trimma is a genus of fish in the family Gobiidae native to the Indian and Pacific Ocean. Together with members of the genus Eviota , they are known commonly as pygmygobies or dwarfgobies.
There are currently 111 recognized species in this genus: [1]
Gobiidae or gobies is a family of bony fish in the order Gobiiformes, one of the largest fish families comprising more than 2,000 species in more than 200 genera. Most of gobiid fish are relatively small, typically less than 10 cm (3.9 in) in length, and the family includes some of the smallest vertebrates in the world, such as Trimmatom nanus and Pandaka pygmaea, Trimmatom nanus are under 1 cm long when fully grown, then Pandaka pygmaea standard length are 9 mm (0.35 in), maximum known standard length are 11 mm (0.43 in). Some large gobies can reach over 30 cm (0.98 ft) in length, but that is exceptional. Generally, they are benthic or bottom-dwellers. Although few are important as food fish for humans, they are of great significance as prey species for other commercially important fish such as cod, haddock, sea bass and flatfish. Several gobiids are also of interest as aquarium fish, such as the dartfish of the genus Ptereleotris. Phylogenetic relationships of gobiids have been studied using molecular data.
Eleotridae is a family of fish commonly known as sleeper gobies, with about 34 genera and 180 species. Most species are found in the tropical Indo-Pacific region, but there are also species in subtropical and temperate regions, warmer parts of the Americas and near the Atlantic coast in Africa. While many eleotrids pass through a planktonic stage in the sea and some spend their entire lives in the sea; as adults, the majority live in freshwater streams and brackish water. One of its genera, Caecieleotris, is troglobitic. They are especially important as predators in the freshwater stream ecosystems on oceanic islands such as New Zealand and Hawaii that otherwise lack the predatory fish families typical of nearby continents, such as catfish. Anatomically, they are similar to the gobies (Gobiidae), though unlike the majority of gobies, they do not have a pelvic sucker.
Chromis is a genus of fish in the family Pomacentridae. While the term damselfish describes a group of marine fish including more than one genus, Chromis is the largest genus of damselfishes. Certain species within the genus are common in the aquarium trade.
Collared wrigglers are perciform fishes in the family Xenisthmidae. They are native to the Indian and Pacific Oceans, where they are mostly reef-dwelling.
Gobiodon is a genus of gobies also known as coral gobies or "clown gobies". Generally, coral gobies, unlike the rest of the family Gobiidae, are not burrowers, but instead prefer to inhabit the branches of certain Acropora or similar hard corals.
Plectranthias is a genus of ray-finned fish in the subfamily Anthiinae, part of the family Serranidae, the groupers and sea basses. They are found in the Atlantic, Indian and Pacific Ocean.
Cirrhilabrus, the fairy wrasses, is a genus of fish in the family Labridae native to coral reefs and nearby habitats in the Indo-Pacific region. They are brightly colored and do not surpass 16 cm (6.3 in) in length. Males are larger and more colorful than females. They are commonly kept in aquaria.
Eviota is a genus of fish in the family Gobiidae, commonly as dwarfgobies found in the Indo-Pacific region, where it is distributed from Japan to Australia and from Africa to Pitcairn Island. Species are mainly associated with coral reefs. Many of these fish are short-lived, with life cycles as brief as 3.5 weeks in the tropics. Some species are hermaphrodites and some representatives live symbiotically among the tentacles of the mushroom coral.
Oligolepis is a genus of fish in the goby family Gobiidae, native to marine, fresh and brackish waters of the coastal areas of the Indian Ocean and the western Pacific Ocean.
Priolepis is a genus of fish in the family Gobiidae with a cosmopolitan distribution.
Vanderhorstia is a genus of gobies native to the Indian and Pacific oceans. The name of this genus honours the Dutch biologist Cornelius van der Horst (1889-1951) of the University of the Witwatersrand, Johannesburg, who was well known for his interest in marine biology.
Tomiyamichthys is a genus of gobies found from the Red Sea through the Indian Ocean to the western Pacific Ocean.
True gobies were a subfamily, the Gobiinae, of the goby family Gobiidae, although the 5th edition of the Fishes of the World does not subdivide the Gobiidae into subfamilies. They are found in all oceans and a few rivers and lakes, but most live in warm waters. Altogether, the Gobiinae unite about 1149 described species in 160 genera, and new ones are still being discovered in numbers.
Asterropteryx is a genus of fish in the family Gobiidae found in the Indian and Pacific Ocean.
Egglestonichthys is a genus of gobies native to brackish and marine waters of the Indian Ocean and the western Pacific Ocean.
Sueviota is a genus of fish in the family Gobiidae native to the Indian and Pacific Ocean.
Trimma tevegae, commonly known as the bluestripe pygmygoby or blue-striped cave goby among other names, is a species of goby from the western Pacific. They are small fish, averaging at 2 cm (0.79 in), orange-brown with white undersides in life, with characteristic iridescent blue or lavender stripes on the sides and on top of the body. They are usually found in large schools in the sloping or vertical drop-offs at coral reef edges. They are sometimes caught for the aquarium trade, and are also known by hobbyists under the name blue line flagtail goby. The species is named in honor of the schooner Te Vega.

Trimma panemorfum is a species of goby from the deep reefs around 91.4 meters (300 ft) at the Uchelbeluu Reef in Palau in the western Pacific Ocean.
