Pomacentridae is a family of ray-finned fish, comprising the damselfishes and clownfishes. This family were formerly placed in the order Perciformes but are now regarded as being incertae sedis in the subseries Ovalentaria in the clade Percomorpha. They are primarily marine, while a few species inhabit freshwater and brackish environments. They are noted for their hardy constitutions and territoriality. Many are brightly colored, so they are popular in aquaria.
Schindleria is a genus of marine fish. It was the only genus of family Schindleriidae, among the Gobioidei of order Perciformes but is now classified under the Gobiidae in the Gobiiformes. The type species is S. praematura, Schindler's fish. The Schindleria species are known generically as Schindler's fishes after German zoologist Otto Schindler (1906–1959), or infantfishes. They are native to the southern Pacific Ocean, from the South China Sea to the Great Barrier Reef off eastern Australia.
Eviota hoesei, Doug's eviota, is a species of goby associated with reefs and tide pools. It has a limited distribution in the southwest Pacific, being found around New Caledonia, Lord Howe Island, Norfolk Island and the Elizabeth and Middleton Reefs at depths of from 0 to 25 metres. Within this limited area this is an abundant species.
Amblyeleotris steinitzi, Steinitz' prawn goby or simply Steinitz' goby, is a species of small fish in the family Gobiidae. It lives in association with an alpheid shrimp and is found from the Red Sea through the Indian Ocean to the western Pacific Ocean.
The Gobiiformes are an order of fish that includes the gobies. The order, which was previously considered a suborder of Perciformes, is made up of 2,211 species that are divided into seven different families. Phylogenetic relationships of the Gobiiformes have been elucidated using molecular data. Gobiiforms are generally small fish and are mostly marine (saltwater) fishes, but roughly 10% of the population inhabit fresh waters. This order is made up of mainly benthic or sand-burrowing fish. Benthic fish live on the bottom of a body of water. Like in most benthic organisms, gobiiforms do not have a gas bladder or swim bladder which keeps them from suspending in the water column, so they must stay on the bottom.
Glossogobius giuris, the tank goby, is a species of goby native to fresh, marine and brackish waters from the Red Sea and East Africa through South Asia and the Indian Ocean to China, Australia and the islands of the Pacific Ocean. This species can also be found in the aquarium trade. It is also known as the bar-eyed goby, flat-headed goby and the Gangetic tank goby.
Valenciennea strigata is a species of fish in the family Gobiidae, the gobies. Its common names include the blueband goby, golden-head sleeper goby, and pennant glider. It is native to the Indian Ocean and the western Pacific Ocean where it can be found in outer lagoons and the seaward side of reefs It inhabits a variety of substrates, sand, rubble, hard, at depths of from 1 to 25 metres. This species can reach a length of 18 centimetres (7.1 in) TL. It can also be found in the aquarium trade. It is the type species of the genus Valenciennea.
Amblyeleotris guttata, the Spotted prawn-goby is a species of goby native to reefs of the Western Pacific Ocean, that includes the Philippines to Tonga, north to the Ryukyu Islands, south to Australia.
Coral reef fish are fish which live amongst or in close relation to coral reefs. Coral reefs form complex ecosystems with tremendous biodiversity. Among the myriad inhabitants, the fish stand out as colourful and interesting to watch. Hundreds of species can exist in a small area of a healthy reef, many of them hidden or well camouflaged. Reef fish have developed many ingenious specialisations adapted to survival on the reefs.
Coastal fish, also called inshore fish or neritic fish, inhabit the sea between the shoreline and the edge of the continental shelf. Since the continental shelf is usually less than 200 metres deep, it follows that pelagic coastal fish are generally epipelagic fish, inhabiting the sunlit epipelagic zone. Coastal fish can be contrasted with oceanic fish or offshore fish, which inhabit the deep seas beyond the continental shelves.
The small-eyed goby is a species of goby native to tropical reefs of the Indian Ocean through the western Pacific Ocean where it inhabits areas of coral rubble. As its common name suggests, this species has particularly small eyes. This species grows to a length of 6 centimetres (2.4 in) TL. This species is the only known member of its genus. The small-eyed goby is specialised to feed on seagrass and they share a burrows with mud lobsters of the genus Thalassina. The specific name honours Charles Melbourne Ward (1903-1966), the Australian actor, naturalist and collector of specimens who collected the type specimen.
Valenciennea helsdingenii is a species of goby from the Indo-Pacific. It is commonly known as the twostripe goby, black-lined sleeper goby, or railway sleeper goby. It can grow up to a length of 25 cm (9.8 in) and is distinguishable by two prominent orange to black lines running longitudinally through its body.
Grallenia is a genus of fish in the family Gobiidae native to the western Pacific Ocean.
Eviota melasma, commonly called headspot eviota or melasma pygmy goby among various other vernacular names, is a species of marine fish in the family Gobiidae.
Amblygobius semicinctus, the halfbarred goby , is a species of goby from Gobiidae family.
Gobiodon quinquestrigatus, commonly known as the five-lined coral goby, is a species of goby. It occurs in the western Pacific from the Philippines to the Society Islands, north to Japan and south to Australia. It is normally found in monogamous pairs associating with corals of the genus Acropora.Its diet consists of small invertebrates and zooplankton. The female deposits the eggs on a coral branch which the male tends. They are able to change sex in whichever direction favours reproductive success. This species has a dark brown body colour with a lighter brown to reddish head which has five vertical blue lines, subadults have additional vertical lines on body.
Elacatinus figaro, the barber goby or yellow line goby, is a colourful species of marine goby, family Gobiidae, from the southwestern Atlantic, where it is endemic to the coastal waters of Brazil.
Ctenogobiops tangaroai, the silver-spotted shrimp-goby, is a species of bony fish of the family Gobiidae, native to the reefs which is widespread in the Indo-West Pacific, from the Red Sea and Western Indian Ocean through northern Australia and Taiwan, southern Japan and Fiji. It occurs in fine-grained sand patches at depths of from 4 to 40 metres where it is commensal with alpheid shrimps, with a fish and shrimp sharing a burrow. This species can reach a length of 6 centimetres (2.4 in) TL. It can also be found in the aquarium trade. It is pale in colour marked with four rows of brown spots or dashes along its flanks, three diagonal rows of short, dark stripes on the posterior of its head with larger dark spots on the lower flanks which are frequently surrounded by smaller blue spots and there is a small white stripe above the pectoral fin base with a longer white streak on the pectoral fin. It is the type species of the genus Ctenogobiops.
