Nannacara is a genus of small freshwater cichlid fish endemic to South America. The genus is part of the Cichlasomatini tribe of the Cichlasomatinae subfamily. In the aquarium hobby, the fish is considered a dwarf cichlid along with Apistogramma , Mikrogeophagus , and Dicrossus species. Nannacara anomala is the most commonly encountered species in the aquarium trade.

Species

There are currently six recognized species in this genus: [1]

In a book published in 2006, Nannacara adoketa and Nannacara bimaculata were reassigned to the new genus Ivanacara . [2] This change has not been recognized by FishBase, [1] but it has been adopted by the Catalog of Fishes. [3]

Cichlids are fish from the family Cichlidae in the order Cichliformes. Traditionally Cichlids were classed in a suborder, the Labroidei, along with the wrasses (Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. On the basis of fossil evidence, it first appeared in Tanzania during the Eocene epoch, about 46–45 million years ago. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of Fishes of the World as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is large, diverse, and widely dispersed. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000.

<span class="mw-page-title-main">Discus (fish)</span> Genus of fishes

Symphysodon is a genus of cichlids native to the Amazon river basin in South America. Due to their distinctive shape, calm behavior, many bright colors and patterns, and dedicated parenting techniques, discus are popular as freshwater aquarium fish, and their aquaculture in several countries in Asia is a major industry. They are sometimes referred to as pompadour fish. The discus fish has attracted a cult following of collectors and has created a multimillion dollar international industry complete with shows, competitions, and reputable online breeders.

Hemichromis is a genus of fishes from the cichlid family, known in the aquarium trade as jewel cichlids. Jewel cichlids are native to Africa. Within West Africa, Hemichromis species are found in creeks, streams, rivers and lakes with a variety of water qualities including brackish water lagoons. As traditionally defined, the genus includes two distinctly different groups: The five-spotted cichlid group and the true jewel cichlid group (Rubricatochromis), which sometimes are recognized as distinct genera.

<i>Apistogramma</i> Genus of fishes

Apistogramma is a large genus of freshwater fish in the family Cichlidae native to South America, but also commonly kept in aquariums. They are dwarf cichlids that mostly feed on tiny animals and have breeding behaviors that vary depending on the exact species.

<i>Aequidens</i> Genus of fishes

Aequidens is a genus of fish in the family Cichlidae found in South America. Formerly a wastebasket genus, as presently defined Aequidens is largely restricted to the Amazon Basin, Orinoco Basin and river basins in The Guianas. The only exceptions are A. plagiozonatus which also occurs in the Paraná Basin, and A. tetramerus which also occurs in the Parnaíba River.

<i>Geophagus</i> Genus of fishes

Geophagus is a genus of cichlids that mainly live in South America as far south as Argentina and Uruguay, but a single species, G. crassilabris is from Panama. They are found in a wide range of freshwater habitats. They are part of a group popularly known as eartheaters and mostly feed by picking up mouthfuls of sediment to sift out food items such as invertebrates, plant material and detritus. The largest species reach up to 28 cm (11 in) in standard length. They are mostly kept in aquariums.

<i>Aulonocara</i> Genus of fishes

Aulonocara is a genus of haplochromine cichlids endemic to Lake Malawi in East Africa. All Aulonocara species are maternal mouth brooders. Particularly in the aquarium hobby, Aulonocara species are also known as peacock cichlids, aulonocaras or simply "peacocks". This genus is strongly sexually dichromic, even by haplochromine standards.

<i>Protomelas</i> Genus of fishes

Protomelas is a genus of haplochromine cichlids endemic to Lake Malawi in East Africa. The genus is part of the haplochromine tribe and have maternal mouthbrooding and sexual dimorphism typical of this group. Popular in the aquarium hobby, Protomelas species are sold under a variety of trade names.

Paraneetroplus is a genus of cichlid fish native to moderately to fast-flowing waters in the Coatzacoalcos, Grijalva and Papaloapan river basins in southern Mexico. They reach up to 20–25.5 cm (8–10 in) in length.

<i>Symphysodon aequifasciatus</i> Species of fish

Symphysodon aequifasciatus, the blue discus or brown discus, is a species of cichlid native to rivers of the eastern and central Amazon Basin downriver from the Purus Arch. This discus is found in black-, clear- and whitewater, but its preference for lentic habitats such as floodplains and flooded forests means that the whitewater it inhabits contain little suspended material. It is largely restricted to water with a high temperature of 25–32 °C (77–90 °F) and a pH of 5.2–7.7.

<i>Rhamphochromis</i> Genus of fishes

Rhamphochromis is a genus of East African haplochromine cichlids endemic to the Lake Malawi basin, also including Lake Malombe, Lake Chilingali, Chia Lagoon and upper Shire River. They mainly occur in offshore open waters, but a few species also near the coast. They are piscivores that typically feed on lake sardines and small utaka cichlids.

<i>Mesonauta</i> Genus of fishes

Mesonauta, the flag cichlids, is a small genus of cichlids native to the Amazon, Orinoco, Essequibo, Paraná and Paraguay basins in South America. Mesonauta is included in the subfamily Cichlasomatinae. They occur in various freshwater habitats such as streams and lakes, especially in areas with little water movement and aquatic vegetation. They are generally found in small groups that stay near the water surface. To avoid predators, adults may jump out of the water and juveniles mimic leaves.

<i>Hemitaeniochromis</i> Genus of fishes

Hemitaeniochromis is a small genus of cichlid fishes endemic to Lake Malawi in east Africa. The genus is distinguished from other genera of Lake Malawi Haplochromini by details of its melanic color pattern and by its dentition. The color pattern includes (1) a midlateral horizontal stripe starting at least an eye length behind the operculum, this stripe broken into separate spots at least on its front half, more nearly continuous on its rear half, extending to the end of the caudal peduncle; (2) a second (supralateral) stripe above the midlateral one that is only on the front part of the flanks, and which is also at least partly broken into spots; (3) above this at the base of the dorsal fin are 4 or 5 dorsal midline spots. The dentition of the jaws is also distinctive in fish at least 10 centimetres in length ; the outer teeth are roughly conical with a single cusp and are spaced apart from each other by about the width of the tooth.

<i>Trichopodus</i> Genus of fishes

Trichopodus is a genus of tropical freshwater labyrinth fish of the gourami family found in Southeast Asia. Gouramis of the genus Trichopodus are closely related to those of Trichogaster ; species of both genera have long, thread-like pelvic fins used to sense the environment. However, Trichopodus species have shorter dorsal fin base and, when sexually mature, are much larger, with the largest, the snakeskin gourami, capable of reaching a length of over 8 in (20 cm).

<span class="mw-page-title-main">Goldeneye cichlid</span> Species of fish

The goldeneye cichlid is a species of cichlid found in fresh water from the Aruka River in Guyana, to the Maroni River in Suriname. It is often found on flooded savannas near the coast. The male grows to a length of about 5.6 centimetres (2.2 in) while the female is somewhat smaller, and is thus regarded as a dwarf cichlid.

Nannacara quadrispinae is a species of cichlid endemic to Venezuela where it is found in the Orinoco delta. It went by the trade name Nannacara sp. Venezuela in the ornamental fish market prior to its formal description. This species can also be found in the aquarium trade.

<i>Ivanacara</i> Genus of fishes

Ivanacara are a genus of cichlid fishes from tropical South America. This genus was identified as a new in 2006, but many authorities do not recognize it and maintain its species in Nannacara.

Rondonacara hoehnei is a species of cichlid fish of the subfamily Cichlinae. This species is endemic to the upper das Mortes River basin in the Araguaia drainage of central Brazil. This species is the only known member of its genus, but it was formerly included in Aequidens. Although not yet rated by the IUCN, it has been suggested that it is seriously threatened and should be considered critically endangered. The specific name honour the collector of the type specimen, the Brazilian botanist Frederico Carlos Hoehne (1882-1959).

<span class="mw-page-title-main">Cichlasomatini</span> Tribe of fishes

Cichlastomatini is a tribe of cichlids from South America, one of two tribes that make up the subfamily Cichlasomatinae. They were recognised in 1983 as an assemblage by the Swedish ichthyologist Sven O. Kullander by their four rather than five 5 dentary foramina in the lateralis canal system of the head, describing them as closely related to the genus Cichlasoma. Melanie Stiassny suggested that these fishes recognised as a clade by Kullander were divided into two groupings in 1991 which she termed cichlasomines and heroines, Kullander formally raised these to the tribes Cichlasomatini and Heroini of the subfamily Cichlasomatinae in 1999. In other classifications the tribe Cichlasomatini is placed in the subfamily Cichlinae.
