Brachygobius is a small genus of gobies. They are popular aquarium fish where a number of species are sold as bumblebee gobies because their colours are similar to those of bumblebees. [1]
Bumblebee gobies range in size from 1.5 cm to 4 cm. [2] They are generally coloured black with pale yellow to orange bands. [3] Males are generally slimmer than females and often have more vivid colours, typically orange rather than yellow. [3] Females may also have smaller and rounder heads. [2] When spawning, the colours of the males become deeper, the orange bands becoming red in the case of Brachygobius doriae. [2]
This genus is informally divided by taxonomists into the dwarf Brachygobius nunus-species group (e.g., B. nunus, B. aggregatus, and B. mekongensis) and the bigger Brachygobius doriae-species group (e.g., B. doriae, B. sabanus, and B. xanthomelas). [2]
There are currently nine recognized species in this genus: [4]
Bumblebee gobies are found across Southern and Southeast Asia primarily in freshwater habitats but also in slightly brackish waters. [2] [3]
These gobies are oviparous. Eggs are deposited in a cave where they are guarded by the male. [3] Clutch size is around 150-200 eggs. [5] The eggs hatch after around seven days and the fry become free swimming another five to seven days later. [3]
Bumblebee gobies are popular aquarium fish. [5] A tank around 40 liters in size will house a dozen specimens comfortably. Under good conditions they can live in an aquarium for around 5 years. [3] The most commonly traded species in the hobby belong to the Brachygobius doriae-species group but the smaller Brachygobius nunus is also traded occasionally. [2] [3] Although many aquarium books use the name Brachygobius xanthozona, this species is very rare in the wild and is not commercially traded. [3]
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.
Batrachoididae is the only family in the ray-finned fish order Batrachoidiformes. Members of this family are usually called toadfish or frogfish: both the English common name and scientific name refer to their toad-like appearance.
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.
The red rainbowfish or salmon-red rainbowfish is a species of rainbowfish from Lake Sentani in Irian Jaya, Indonesia. Belonging to the family Melanotaeniidae, in the subfamily Melanotaeniinae, the Australian rainbowfishes. It is threatened in its native range, but easily bred in captivity and common in the aquarium trade.
Synchiropus splendidus, the mandarinfish or mandarin dragonet, is a small, brightly colored member of the dragonet family, which is popular in the saltwater aquarium trade. The mandarinfish is native to the Pacific, ranging approximately from the Ryukyu Islands south to Australia. It can usually be found in some of the warmer waters.
A brackish-water aquarium is an aquarium where the water is brackish (semi-salty). The range of "saltiness" varies greatly, from near freshwater to near marine and is often referred to as specific gravity (SG) or salinity. Brackish water aquaria is a popular specialization within the fishkeeping hobby. Many species of fish traded as freshwater species are actually true brackish species, for example mollies, Florida flagfish, and some cichlids such as chromides and black-chin tilapia. There are also several popular species traded purely as brackish water fish, including monos spp, scats, archerfish, and various species of pufferfish, goby, flatfish, and gar. Generally, aquarists need to maintain a specific gravity of around 1.005 to 1.010 depending on the species being kept, but practically all brackish water fish tolerate variations in salinity well, and some aquarists maintain that regularly fluctuating the salinity in the aquarium actually keeps the fish healthy and free of parasites.
Pristella maxillaris is a species of characin in the genus Pristella, and is commonly known as the X-ray fish or X-ray tetra because of its translucent body. It is a widely distributed and adaptable fish, found in the Amazon and Orinoco basins, as well as coastal rivers in the Guianas in both acidic and alkaline waters. Unlike most other characins, it is tolerant of slightly brackish water. It is small and lives in large groups, and males can be distinguished from females by being smaller and thinner than the females. Like most other tetras, it feeds primarily on small insects and planktonic animals.
The dwarf pygmy goby or Philippine goby is a tropical species of fish in the subfamily Gobionellinae from brackish water and mangrove areas in Southeast Asia. It is one of the smallest fish species in the world. Males reach maturity at a standard length of 0.9 cm (0.35 in) and can reach up to 1.1 cm (0.43 in) in standard length, while the females can grow up to 1.5 centimetres (0.59 in) in total length. Adults weigh around 4 milligrams (0.00015 oz). It is known as bia and tabios in the Philippines.
Hypseleotris is a genus of fishes in the family Eleotridae. Most are from fresh water in Australia and New Guinea, but species in fresh and brackish water are found around islands in the western Indian Ocean, southern and eastern Africa, southern and eastern Asia, and Pacific islands. The largest species reaches a length of 12 cm (4.7 in). They are sometimes seen in the aquarium trade; especially H. compressa. In Australia they are known as carp gudgeons.
The Gobiiformes are an order of fish that includes the gobies and their relatives. The order, which was previously considered a suborder of Perciformes, is made up of about 2,211 species that are divided between seven families. Phylogenetic relationships of the Gobiiformes have been elucidated using molecular data. Gobiiforms are primarily small species that live in marine water, but roughly 10% of these species inhabit fresh water. This order is composed chiefly of benthic or burrowing species; like many other benthic fishes, most gobiiforms do not have a gas bladder or any other means of controlling their buoyancy in water, so they must spend most of their time on or near the bottom. Gobiiformes means "goby-like".
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.
Elacatinus puncticulatus is a species of goby from the eastern central Pacific Ocean, where it is found on reefs from the Gulf of California to Ecuador. This species occurs at depths ranging from 1 to 21m, and usually in association with the sea urchin Eucidaris thouarsii. The size of the goby varies depending on sex, with females being typically smaller than males, and their geographical location as well as their role as a cleaner goby also has impacts on their morphology. Due to their bright coloration and lack of aggression, the species is commonly found in the aquarium trade.
Brachygobius nunus, the Golden banded goby, is a species of bumblebee goby, a small genus of gobies that takes its common name from their round bodies, big heads, and their overall yellow to golden coloration interrupted by four brown to black vertical stripes reminiscent of the striped pattern of a bumblebee. They have also been figuratively described as "buzzing" from one surface to another inside the aquarium. Like other members of its genus, it is popular as an aquarium fish.
The violet goby is a species of goby native to marine, fresh and brackish waters near the Atlantic coast of North and South America from South Carolina in the United States of America, to northern Brazil. It prefers bays, estuaries and river mouths with muddy substrates. It is often marketed as the dragon goby or dragon fish.
Brachygobius doriae, the bumblebee goby, is a species of goby native to fresh and brackish waters of Indonesia, Brunei and Singapore, Malaysia, Cambodia, Thailand and Vietnam. This species can reach a length of 4.2 centimetres (1.7 in) TL. It is listed as Least Concern as no threats are known and it is popular in the aquarium trade.
Zenarchopteridae, the viviparous halfbeaks, is a family in the order Beloniformes. The Zenarchopteridae exhibit strong sexual dimorphism, practicing internal fertilisation, and in some cases ovoviviparous or viviparous. The members in the family are mainly found in fresh and brackish water of tropical Asia and New Guinea, but the genus Zenarchopterus also includes marine species from the Indo-Pacific. Several, such as the wrestling halfbeak, have become commonly traded aquarium fish.
Pandaka is a genus of fish in the goby subfamily, Gobionellinae, native to fresh, brackish and marine waters of Asia and the western Pacific Ocean. Some species in the genus are among the smallest fish in the world; the male P. pygmaea can be just 9 mm (0.35 in) in standard length at maturity.
The frillfin goby is a species of marine fish in the genus Bathygobius.
Brachygobius mekongensis is a species of goby from the subfamily Gobionellinae which is found in the Mekong basin in southern Vietnam, Thailand, Cambodia and Laos where it lives in slow flowing waters and swamps among tangled roots and vegetation. This species is infrequently recorded in the aquarium trade and is potentially threatened by degradation of its habitat by drainage, water diversion and the building of dams and bridges.
Pseudocorynopoma doriae, or the dragonfin tetra, is a species of freshwater fish in the genus Pseudocorynopoma. It is native to inland waters in South America.
