The goatfishes are fish of the family Mullidae, the only family in the order Mulliformes. The family is also sometimes referred to as the red mullets, which also refers more narrowly to the genus Mullus.
Northeast India, officially known as the North Eastern Region (NER), is the easternmost region of India representing both a geographic and political administrative division of the country. It comprises eight states—Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland and Tripura, and the "brother" state of Sikkim.
Hypostomus is a genus of catfish in the family Loricariidae. They are native to tropical and subtropical South America. H. plecostomus is the popular freshwater aquarium fish formerly known as Plecostomus plecostomus. The taxonomic structure of the Loricariidae is still being expanded by scientists. Hypostomus is a highly species-rich and widely distributed catfish genus.
Scleropages is a genus of fish in the family Osteoglossidae found in Asia and Australia. All of these species are carnivorous and have great jumping ability. These species are highly valued as aquarium fish, particularly by those from Asian cultures. In 2003, a study redescribed several naturally occurring color varieties of S. formosus into four separate species. The majority of researchers dispute these redescriptions, arguing that the published data are insufficient to justify recognizing more than one Southeast Asian species of Scleropages and that divergent haplotypes used to distinguish the color strains into isolated species were found within a single color strain, contradicting the findings. They are considered monotypic, consisting of closely related haplotypes based on color. The ancestor of the Australian arowanas: S. jardinii and S. leichardti, diverged from the ancestor of the Asian arowanas about 140 million years ago, during the Early Cretaceous period. The morphological similarity of all seven species shows that little evolutionary change has taken place recently for these ancient fish. The genus had a much wider distribution during the early Cenozoic, with fossil remains known from the Paleocene of Niger and Belgium, and from the Eocene of China.
Mokokchung District (Pron:/ˌməʊkɒkˈtʃʌŋ/) is a district of Nagaland state in India. The town of Mokokchung is its headquarters. The district is the home of the Ao Nagas. It is bounded by the state of Assam to its north, Wokha District to its west, Tuensang District and Longleng District to its east, and Zünheboto District to its south.
Trichogaster is a genus of gouramis native to South Asia from Pakistan to Myanmar. It is the only genus in the monotypic subfamily Trichogastrinae as set out in the 5th Edition of Fishes of the World, although that book states that there are two genera, the other being Colisa which is treated as a synonym of Trichogaster by Fishbase and the Catalog of Fishes. Fishbase also places the genus in the Luciocephalinae. Species of this genus are very popular in the aquarium trade.
Pseudolaguvia is a genus of South Asian river catfishes. These species inhabit hill streams and large rivers. P. tenebricosa is found in fast running, clear water; the river has a sandy bottom and numerous rocks and boulders and aquatic vegetation is absent. P. inornata is from clear, shallow, moderately flowing streams with a predominantly sandy bottom. P. muricata is found in clear, shallow, slow-flowing streams with a mixed substrate of sand and detritus; these fish are found amongst detritus in areas with current. P. ferula is also found in swift flowing waters with a mixed rocky/sandy bottom.
The Dhansiri is a river of Golaghat District of Assam and the Chümoukedima District and Dimapur District of Nagaland. It originates from Laisang peak of Nagaland. It flows through a distance of 352 kilometres (219 mi) from south to north before joining the Brahmaputra on its south bank. Its total catchment area is 1,220 square kilometres (470 sq mi).
Microctenopoma ansorgii is a small freshwater fish, known in the aquarium trade as the ornate ctenopoma, orange ctenopoma, ornate climbing perch, pretty ctenopoma, or rainbow ctenopoma. It is related to the more familiar spotted climbing perch, but looks very different. Its body is more elongated and rounded, with fins with red and black stripes; the color intensifies when the fish are displaying, with black bars becoming visible on the body. The ornate ctenopoma spawns at night, laying its eggs on a floating bubble nest like its relatives in the osphronemidae. It lives in the slow-flowing forest streams of the Congo Basin, where it feeds on worms, insect larvae, and other aquatic invertebrates. It is the most common member of its genus in the aquarium trade, where it is known for being a shy, easily bullied fish that needs live or frozen foods and which benefits from the presence of smaller dither fish to encourage it to come out of hiding.
Bagarius is an Asian genus of catfishes of the family Sisoridae. It includes five to six extant species and potentially one extinct fossil species, B. gigas.
Badis badis, also known as the blue perch or blue badis, is a small species of Asian freshwater fish in the family Badidae of the order Anabantiformes. It is found in ponds, rivers, ditches and swamps in northern India, eastern Pakistan, Bangladesh, Bhutan and Nepal, including the Ganges, Brahmaputra, Mahanadi and Indus basins. It is sometimes kept as an aquarium fish. It is a small, predatory fish that feeds on tiny invertebrates. Maximum total length is around 8 cm (3 in). It is sexually dimorphic, with males growing larger and being more colorful, especially when excited, compared to females. Adult males have blue fins and may display dark vertical bands on the flanks, while the smaller females display little color. Several similar relatives, now recognized as separate Badis species, have historically been confused with Badis badis. Historically the two genera that now make up the Badidae, Badis and Dario, were placed in the family Nandidae; this is no longer the case.
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish, and hypogean fish.
Physoschistura is a genus of fish in the family Nemacheilidae found mostly in Southeast Asia.
The Badidae or the chameleonfishes are a small family or ray-finned fishes which has been placed in the order Anabantiformes. Despite their apparent affinity to other Anabantiforms, the 5th edition of Fishes of the World classifies the family as being a sister to the Anabantiformes, along with the Nandidae and Pristolepididae in an unnamed and unranked but monophyletic clade which is a sister to the Ovalentaria within the wider Percomorpha. Members of this family are small freshwater fish that are found in Bangladesh, Bhutan, China, India, Laos, Myanmar, Nepal, Pakistan and Thailand. The largest is Badis assamensis that reaches a standard length of up to 7.5 cm (3 in), while the smallest, Dario dario, does not exceed 2 cm (0.8 in).
Badis is a genus of freshwater fish in the family Badidae found in South Asia, Southeast Asia and China. These species have a sharp spine on the opercle, soft and spinous parts of the dorsal fin contiguous, three spines in the anal fin, tubed pores in the lateral line, villiform teeth and a rounded caudal fin. In addition, they differ from the related genus Dario by being larger and displaying more involved parental care.
Dario is a genus of very small chameleonfishes native to streams and freshwater pools in China (Yunnan), India and Myanmar. Depending on exact species, they are up to 1.5–3 cm (0.6–1.2 in) in standard length, and reddish or brownish in colour.
Badis ruber is a species of freshwater ray-finned fish from the family Badidae. It is found in Mekong, Salween and Irrawaddy river basins of southeastern China, Laos and Thailand. This species grows to a length of 5.0 cm (2.0 in).
Badis khwae is a species of freshwater ray-finned fish from the family Badidae that is native to Thailand. First described in 2002, this species grows to a length of 2.9 cm.
The Anabantiformes, collectively known as labyrinth fish, are an order of air-breathing freshwater ray-finned fish with two suborders, five families and having at least 207 species. In addition, some authorities expand the order to include the suborder Nandoidei, which includes three families - the Nandidae, Badidae and Pristolepididae - that appear to be closely related to the Anabantiformes. The order, and these three related families, are part of a monophyletic clade which is a sister clade to the Ovalentaria, the other orders in the clade being Synbranchiformes, Carangiformes, Istiophoriformes and Pleuronectiformes. This clade is sometimes referred to as the Carangaria but is left unnamed and unranked in Fishes of the World. This group of fish are found in Asia and Africa, with some species introduced in United States of America.
Channa royi, the Andaman emerald snakehead, is a species of snakehead fish endemic to the Andaman and Nicobar Islands of India. This dwarf snakehead is distinct from other snakehead species due to its differing coloration, number of vertebrae, and teeth, most notably its greenish-gray dorsum. It was only scientifically described in 2018 and its closest relative is the Burmese snakehead, and a review in 2019 argued that the two are synonyms.
