C. choprae has only been available since 2003 but has quickly established itself as one of the most popular small danios in the hobby. There has been some confusion regarding the correct spelling of the specific name with many resources listing it incorrectly as "choprai". Briefly, when Hora described the species he named it after a man, Dr B. N. Chopra, meaning that "choprai" is technically correct as under ICZN rules the specific name ought to follow the gender of the indiv...

This species is sometimes sold under the trade name of 'chameleon fish' due to its ability to rapidly change colour, especially when breeding or stressed. It was originally described as Labrus badis by Hamilton but Bleeker reclassified it as Badis buchanani in 1854; he had adopted the species name 'badis' as the new name for the genus and wished to avoid using a tautonym. At that time the use of tautonyms was avoided in zoological taxonomy but is now permissible under ICZN ru...

This species was only described to science in 2005, the species name being taken from the name of a local tribe. It's also known as the spotted orange seam plec, due to its patterning. It's found living alongside other Loricariid species in nature, including Peckoltia and other Hemiancistrus species. There's ongoing discussion as to whether this species and the currently undescribed L122 are one and the same, as these two were apparently both included in the scientific description...

Also known as the knob nosed whiptail, this species is difficult to confuse with any other Loricariid due to its distinctive 'diamond' shape when viewed from above, and peculiarly shaped rostrum (nose), which is enlarged at the tip. It also lacks discernible odontotes on the head and pectoral fins. So distinctive is it, in fact, that it is currently monotypic (the only species in its genus). The species name is derived from its superficial resemblance to the sturgeons of the genus Acip...

Not to be confused with the other species commonly sold under the name "blue tetra", Knodus borki, this species is much scarcer in the hobby. It also makes a better resident of the community tank than its cousin, being less boisterous and lacking the tendency to nip the fins of other species....

There are currently 4 described subspecies of Melanotaenia splendida. The principle differences are generally in colour, pattern and fin counts, although even these vary depending on the locality of the fish. M s. splendida in particular also exhibits a wide variation in colour and patterning depending on locality within the subspecies, and the species name is often suffixed with a place name when the fish are seen for sale. The different forms and subspecies should not be mixed in the aquarium,...

Although sometimes referred to by the vernacular name 'big spot barb' this species is better known in the aquarium hobby as 'clown barb'. It has been widely misidentified as the congener B. everetti, a distinct and uncommonly-traded species from Borneo and thus appears under that name in the majority of available literature. The two are quite easy to tell apart, with B. everetti an overall les...

Localities known in the hobby include 'Pastaza', 'Putumayo', 'Requena', 'Río Nanay', 'Rio Napo', 'Maniti', 'Momón', 'Río Tigre', 'Río Ampiyacu', 'Shishita', 'Shushupi', 'Yavari', 'Tefé', 'Manaquiri', 'Lago do Januari', 'Mamori' (often misspelled 'Mamuri'), 'Careiro', 'Manacapuru', 'Juruá', 'Curuaí', and 'Purutu' though we've been unable to find anywhere matching the latter name within the species' known distribution, and in fact several of these names are applied incorrectly on a regular basis.

This species was named the millenium cory because it was the first catfish species to be described in the year 2000. It was in fact described in late 1999, but the date of the journal containing the information was 01/2000. There are 4 other species of cory that may be confused with C. spectabilis at first glance. These are C. guapore, C. ourastigma, C. similis and C. caudimaculatus. They can be distinguished quite easily upon close examination, however. C. guapore, whilst exhibiting similar pat...

This species lends it name to the B. bellica group/complex of closely-related species within the genus, an assemblage of which members share the following set of characters: long and slender body with dorsal and ventral margins almost parallel; body depth 23-28 % SL; 30-33 anal-fin rays; 11-13 dorsal-fin rays; 32-34 total vertebrae; body dark brown in colour with iridescent green markings on each individual scale.

This species lends its name to the Betta foerschi group of closely-related species within the genus, of which members share the following set of characters: possession of iridescent blue or green unpaired fins; rays and interradial membranes in unpaired fins not contrasting; dorsal fin with thin, bright white distal band; opercle with two, reddish-yellow, vertical bars. Members are regarded as being closely-related to bubble nesting Betta specie...

This species lends its name to the Betta picta complex of closely-related species, an assemblage of which members share the following combination of characters: unpaired fins rounded (anal fin sometimes pointed): I-III, 18-24 anal-fin rays; anal and caudal fins with dark distal margins, most pronounced in mature males; pre- and post-orbital stripes present; chin bar present; opercle with iridescent blue, green, or gold scales.

This species is uncommon in the aquarium trade although its name is sometimes applied to other species. It was originally described in the monotypic genus Pseudopristella, and can be distinguished from the vaguely similar Pristella maxillaris by possession of a relatively large (vs. relatively small) humeral spot and having black pigmentation in the anal-fin restricted to the first ray (vs. a prominent distal blotch).

L. cyclorhynchus was described twice in the space of two years, with Pellegrin erecting Labeo variegatus for it in 1901. Although the invalidity of the variegatus name is quite well-documented you may still see the species named as such in older literature, trade lists and by some websites. It's also worth noting that the attractive patterning seen in young fish does fade with age, the adults being much darker in colour. The genus Labeo currently contains over 100 species but is in dire ...

Despite its extensive natural distribution S. lilith is uncommon in the ornamental trade, where it is sometimes referred to as 'one-spotted demon fish' or 'one spot eartheater'. It can be distinguished from other members of the genus by possessing a single dark blotch on the flank and a prominent ocellus at the caudal-fin base. Among the named species it is most similar to S. daemon, but that species possesses two blotches on the flank.

This species is still sometimes listed as a species of Lebias by some sources although that name has long been considered a synonym of Cyprinodon by most authorities and an ICZN committee voted to suppress the name in favour of Aphanius as recently as 2003. It was known as A. persicus until late 2011 when it was reclassified due to that name being preoccupied by a Late Miocene fossil species previously referred to as Brachylebias persicus Priem 1908. This change was necessary because Gau...

This species lends its name to the 'G.' steindachneri, an assemblage of closely-related species with unresolved generic placement which currently also includes 'G.' crassilabris and 'G.' pellegrini. It exists in a number of colour forms which vary with locality, some of which may eventually be described as separate taxa. Some of these may appear on trade lists under the synonym Geophagus hondae.

This species was previously referred to as M. thoracata, but that name is now applied to the species with a relatively short dorsal-fin spine which was formerly known as M. personata. M. picta can be told apart from M. thoracata by presence of a dark vertical bar in the caudal-fin, a comparatively longer dorsal-fin spine (52.0-64.0% vs. 32.0-48.0% of dorsal-fin base in specimens measur...

A gentle giant ideal for the larger community of Malawi cichlids, this species was formerly named Haplochromis moorii. It is occasionally referred to by the common name, "Humphead Mouthbrooder". In nature, it exhibits an interesting feeding behaviour in which it will be attracted to clouds of sand thrown up by the activity of substrate-sifting species such as Fossorochromis rostratus or Taeniolethrinops praeorbitalis. Shoals of C. moorii will follow these species and feast on any mo...

The species name 'furcidens' is derived from the interesting fork-shaped teeth of this fish. This species may develop a cervical hump as it matures. As with other goodeids, there is less of a size difference between the sexes than in many other livebearers. This is thought to be related to the relatively primitive structure of the andropodium, as the fish tend to choose mates that are of similar size so that the sex organs are synchronised. Goodeids are unique among livebearers in t...
