This species is included in the so-called "Brichardi complex", which also includes N. brichardi, crassus, falcicula, gracilis, pulcher, savoryi and splendens. These should not be mixed in aquaria, as they will hybridise freely. N. olivaceouscan be distinguished from others in the complex by the two curved markings on the gill cover. It is possible that it is synonymous with N. pulcher, as proposed by Konings (1993)....

This species is included in the so-called "Brichardi complex", which also includes N. brichardi, crassus, falcicula, gracilis, helianthus, olivaceous, pulcher, and splendens. These should not be mixed in aquaria as they will hybridise freely. N. savoryi can be distinguished from others in the complex by it's distinctive patterning of vertical bars....

Several geographical morphs of this species are available, including "Sambia" and "Kipili". These vary in base colour from blue to yellow to white. It is not recommended for the general Tanganyikan community due to its aggressive and predatory nature....

N. similis is one of the less frequently seen shelldwellers in the hobby but has no less personality than its cousins. The territories it establishes are very small, usually measuring no more than 6" across, but they are defended vigorously. The tiny fish will even bite hands or fingers that invade their 'personal space'! It can be distinguished from the similar N. multifasciatus by the presence of additional barring on the head and neck and also in this species the stripes appear...

It can be distinguished from the similar N. sexfasciatus by the presence of only five, rather than six, vertical bars on it's flanks. It is not recommended for the general Tanganyikan community due to it's aggressive nature, particularly when breeding....

One of the most popular and instantly recognisable fishes in the aquarium hobby, this species has been selectively-bred to produce a number of additional strains including albino, 'golden' (leucistic), short-bodied, long-finned and 'diamond' (in which the dorsal surface is covered in reflective scales). Unfortunately years of commercial breeding have somewhat affected the genetic vigour of the ornamental strain meaning morphological defects an...

For aquarists perhaps more useful are the subtle differences in colour pattern with P. simulans differing from both P. innesi and P. axelrodi in possessing a greener (vs. bluer) lateral stripe which covers more (vs. less) of the eye/head and extends to the caudal-fin base (vs. terminating anterior to caudal-fin base), a lesser (vs. greater) amount of relatively duller (vs. brighter) red pigmentation on the flanks. The taxonomic history of all three species is complicated with earlier authors such as Géry (1960, 1977) ten...

Euryhaline and thus capable of withstanding significant fluctuations in salinity and other water conditions. It's been recorded in full marine conditions as well as pure freshwater environments, and commonly inhabits coastal mangrove creeks and swamps. Such changes may occur on a daily or seasonal basis depending on locality, with some habitats influenced by daily tides whereas others become hypersal...

This species has been traded for a number of years, though not always under the correct name. We've seen it on sale as S. elegans or S. atropurpureus on numerous occasions, for example, and other trade names include 'Sumatran blue neon goby', 'cobalt blue goby' and 'freshwater neon goby'. Further confusion has arisen because other species are sometimes sold as S. semoni meaning identification has not always been easy and there ...

This species is available in the trade on occasion and has been sold as Danionella sp. 'neon green' or 'flourescent green'. The specific name was inspired by its jaw morphology which according to current knowledge is unique among cypriniform fishes. Both upper and lower jaws contain a series of toothlike odontoid processes; these are only rudimentary in females but in males appear to form rows of teeth of which the front pair is large and fang-like. The upper fangs project th...

Also known as the costello or green neon tetra, this species is seen much less often in the hobby than it used to be. It's occasionally confused with the common head and tail light tetra, H. ocellifer, as it resembles an elongated version of that species. Like all Hemigrammus, its taxonomic status is currently Incertae Sedis, meaning uncertain. The genus is currently used as something of a catch-all for over 70 species of small characin. Most experts agree that a full revision is require...

The water at the type locality is described as 'clear and fast-flowing over a rocky substratum'. H. parclitella was observed in shallow water among the rocks, and sympatric species included Garra cambodgiensis, Neolissochilus soroides, Poropuntius smedleyi, 'Puntius' binotatus, Homaloptera nebulosa and Amblyceps mangois.

The differences in pelvic-fin structure and gill openings led Roberts to redefine the genus when describing H. eubranchus, whereas Tan (2006) expressed doubts that the two are even congeneric but was unable to reach a definitive conclusion in the absence of fresh material. At any rate both species can be easily differentiated from Gastromyzon and Neogastromyzon spp. by observing the mo...

M. ramirezi is also known by the names 'Ramirez' dwarf cichlid' and 'butterfly cichlid' and is among the more popular dwarf cichlids in the aquarium hobby. As a result, it is produced on a commercial basis in huge numbers and a number of ornamental strains have been developed including 'gold', 'long-finned' (both blue and gold forms; also traded as 'lyre-tail', 'veil-tail' and 'hi-fin'), 'electric/neon blue', 'super neon blue gold' 'pearl/perlmutt' and 'balloon'.

Not often seen for sale this is a pretty, peaceful little fish that deserves more popularity in the hobby. It is often confused with similar-looking members of the genus Neolebias.

This fish is sometimes traded as Oreichthys cosuatis, O. sp. 'high fin', O. 'umangii' (a nomen nudum that has only ever been applied to an image of a fish in the book 'Ornamental Aquarium Fish of India'; K. L.Tekriwal and A. A. Rao 1999), Puntius 'arunavii' or 'neon highfin barb'. It can be distinguished from congeners by the following combination of characters: absence of a dark marking in the anal-fin (vs. presence in other species); ½7½ scales scales between pelvic-fin origin and dorsal midline (vs. ½6½ in O. cosuatis and...

This species was discovered in 2009 and as far as we know it has only been collected for the aquarium hobby on a single occasion to date, by Jeffrey Christian of Maju Aquarium, Frank Evers and Hans-Georg Evers. Prior to description it was referred to as O. sp. 'Kendari', O. sp. 'neon' or O. sp. 'Sulawesi'.

O. lithobates is a true rock dweller and is hardly ever seen in open water, even in aquaria. In fact, the scientific name lithobates literally translates as "rock dweller". Breeding males of this species rank among the most stunning of Lake Malawi Haplochromine cichlids. The three characteristic spots on the flanks disappear and are masked by a stunning neon blue patterning. Almost the entireand top of the head turn a deep yellow-orange colour. The most colourful variant is the "...

This species' identity was settled and a neotype designated by Knight (2013), with its validity having been discussed since the late 19th century. P. canius and the closely-related P. gelius were both described by Hamilton (1822) and share the type locality of 'northeastern Bengal'. Although Hamilton did not provide drawings M'Clelland (1839) included colour illustrations depicting two quite different-looking species.

Generally considered one of the hardiest small cyprinids available in the aquarium hobby, P. conchonius is an excellent choice for the beginner. Selective breeding has produced various ornamental strains including long-finned, 'veil-tail', 'super red', 'neon', and 'golden' forms. It's also been hybridised with some congeners although the offspring of such experiments are apparently infertile. It was formerly included in th...
