Hyalobagrus is a genus of catfishes (order Siluriformes) of the family Bagridae. Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates The Actinopterygii (the plural form of Actinopterygius) comprise the class of the ray-finned fishes. Catfish ( order Siluriformes) are a very diverse group of bony Fish. Bagridae are a family of Catfish that originate from Africa and Asia from Japan to Borneo. A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic Catfish ( order Siluriformes) are a very diverse group of bony Fish. This article is about the taxonomic rank for the sequence of species in a taxonomic list see Taxonomic order In scientific classification used In Biological classification, family ( Latin Bagridae are a family of Catfish that originate from Africa and Asia from Japan to Borneo. It includes three species, H. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank. flavus, H. leiacanthus, and H. ornatus. [1]

Distribution
Hyalobagrus species are distributed in Asia. H. flavus is currently known only from the Batang Hari drainage in Sumatra and the Mentaya River basin in southern Borneo. Sumatra (also spelled Sumatera) is the sixth largest island in the world (approximately 470000 km² and is the largest island entirely in Indonesia (two Borneo is the third largest island in the world and is located at the centre of Maritime Southeast Asia. [2] H. leiacanthus is currently known only from the Kapuas River and the Barito River basins in central Borneo. The Kapuas River ( Sungai Kapuas) is located in West Kalimantan, Indonesia. Barito is a river in South Kalimantan, Indonesia which passes through the city of Banjarmasin. [3] H. ornatus originates from the Muar River drainage in the southern Malay Peninsula of Malaysia and Kapuas basin in western Borneo. The Muar River is a river which flows through the states of Negeri Sembilan and Johor in Malaysia. The Malay Peninsula or Thai-Malay Peninsula (Semenanjung Tanah Melayu (คาบสมุทรมลายู is a major Peninsula located in Southeast For the biogeographical region see Malesia Malaysia (məˈleɪʒə or /məˈleɪziə/ is a country that consists of thirteen states and [4]
Physical description
These catfish species are small and transparent. [5] The three species can be distinguished by differences in body shape, coloration, and the degree of serrations on the anterior edge of the pectoral fin spine. The Anatomy of Fish is primarily governed by the physical characteristics of Water, which is much denser than air holds a relatively small amount of dissolved [6] The three species range from about 3–4. 4 centimetres (1. A centimetre ( American spelling: centimeter, symbol cm) is a unit of Length in the Metric system, equal to one hundredth 2–1. 7 in) SL. Inches redirects here To see the Les Savy Fav album see Inches. Fish measurement refers to the measuring of the length of individual fish and of various parts of their anatomy. [2][3][4]
Hyalobagrus species are sexually dimorphic, males possess a genital papilla, and gravid females are easy to spot since their blue-green eggs are visible through their bellies. Sexual dimorphism is the systematic difference in form between individuals of different Sex in the same Species. In Medicine, gravidity refers to the number of times a woman has been Pregnant. [5]
Ecology
These catfish are mid-water swimmers. [5] They are also schooling fish. [6] H. flavus inhabits brown water habitats that are closely associated with blackwater peat swamps. Peat is an accumulation of partially Decayed Vegetation matter. [6] H. ornatus also inhabits peat. [4] In the wild, H. flavus occur in large shoals, sometimes mixed with other species of shoaling catfish such as Pseudeutropius brachypopterus and P. moolengurghae. In their natural habitat, they are almost always found closely associated with submerged vegetation. [6]
In the aquarium
H. flavus and H. ornatus are known to be exported for the aquarium trade. An aquarium (plural aquariums or aquaria) is a Vivarium consisting of at least one transparent side in which Water -dwelling Plants [6][4] H. flavus first appeared in the hobby in the 1980s. [6] They seem to do best in a heavily planted tank with tankmates that will not out compete them for food. [5] They are a peaceful, diurnal community species that accept all kinds of foods. [6] None of these species have been bred in captivity. [5]
