Has been recorded from major river channels, smaller tributaries, and floodplain lakes, many of which comprise acidic, mineral-poor blackwater environments with brownish, tannin-stained water, although it has been observed to inhabit clear waters as well. Many of its habitats lie within the Venezuelan and Colombian llanos, a vast, highly biodiverse system of tropical savannah grasslands, seasonally-flooded plains and forests covering an area measuring almost 600,000 square kilo...

This miniature look-a-like of the popular Rasbora trilineata is rarely seen in the aquatic hobby, probably as a result of its relatively plain patterning and rather delicate nature. However if a group is well looked-after they will exhibit some interesting behaviour and surprising colour. As it also makes an ideal resident of the ornamental planted aquaria that are currently so popular in the hobby we'd love to see it become more widely-available. The genus is currently monotypic and dis...

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 not a well-known aquarium fish but is maintained by a number of Indian enthusiasts. It can be told apart from related species by the following combination of characters as per Sreekantha et al. (2006): pectoral-fin rays 10; absence of black spot at base of dorsal-fin; presence of rows of spots on caudal-fin; lateral line incomplete; caudal-fin slightly emarginate; 11-14 vertical bars on the body.

This fish was collected for the aquarium trade during 2012 but its identity has not yet been established. The fish in our images were obtained at an unspecified locality in the Garo Hills, these for...

This species was referred to as S. sp. 'orange fin' or S. sp. 'ST01' prior to being offically named and is one of the more commonly-traded members of the genus, though often in batches containing only one gender, a mixture of species, or misidentified under an incorrect name such as S. zebrinus. It can be told apart from congeners by the following combination of characters: usually 9 soft second dorsal-fin rays; 15 soft pectoral-fin rays; first dorsal-fin in male poin...

It can be distinguished from congeners by its small adult size and presence of a single solid dark midlateral stripe on the body, above which is a series of dark blotches forming a second stripe. In the similar but larger, T. schalleri the upper stripe is more variable depending on the mood of the fish, sometimes fading entirely.

Vieja bifasciata are often confused for vieja synspilum but can be told apart as bifasciata have two prominent horizontal lines running between their eyes (hence the name). They are a very colourful fish and respond to their owner's presence - usually looking for food! Bifasciata are not particularly demanding in terms of water parameters and easy to keep, especially if suitable tankmates can be found. It is sometimes the case that a pair of fish that will not live together in a tank on ...

This species is assigned the code A188 under the DATZ system and is also known by the trade names A. sp. 'Inca/Inka', A. sp. 'Inka 50', A. sp. 'highfin nijsseni', A. sp. 'Nijsseni 2', A. sp. 'red crescent' or A. baenschi 'Inca'. It's among those members of the genus produced on a commercial basis and is regularly available in the aquarium trade.

This species is included in the Betta waseri group/complex of closely-related species within the genus, an assemblage which also includes a handful of potentially new species such as B. sp. 'Medas' on an unofficial basis. Group members share the following combination of characters: base body colouration clay yellow; opercle scales iridescent gold in mature males of all species except B. tomi; throat with black markings which join with black lower jaw in some species; no chin bar.

This species was available in the aquarium hobby for a number of years prior to description and continues to be traded under various names including C. sp. 'Lal Cheng', C. sp. 'Assam', C. sp. 'blue bleheri', C. sp. 'himalayanus', and C. sp. 'red'. The names of valid, but distinct, congeners such as C. amphibeus, C. bleheri or C. stewartii have also been misapplied to it.

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...

The genus Apistogramma is among the most speciose of South American cichlid genera with around 70 species valid at present but many more awaiting description. In addition many species exist in two or more geographical colour forms which may or may not turn out to be distinct in the future. Hobbyists tend to label these with collection data if available in order to avoid mixing them and the potential of hybridisation. Member species have also been organised into a series of species lineages, sublineages, complexes and groups by authors in order to better separate them.

A species for the specialist, E. erythrinus is also known as the rainbow wolf fish or red hi-fin wolf fish. It is quite variable in colour and pattern depending on collection locality. There is a variant from Peru that has a bright orange belly. Recent studies have highlighted genetic differences in these different populations, suggesting that E. erythrinus is actually a species complex, rather than a single species. There is currently one other recognised species in the genus, E. kessleri, but ...

Not a common fish in the trade, most of the specimens imported come in as contaminants among batches of more popular species. Like all Hemigrammus, the taxonomic status of this species 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 required, with the likely outcome that many species will be placed into new or different genera....

For many years this species has (and still is) imported as Pelteobagrus ornatus. It was assigned to the new genus Hyalobagrus, and discovered to be a distinct species, during a taxonomic revision of the Bagridae family in 1998. The other 2 species which were also thought to be P. ornatus are H. leiacanthus and H. ornatus. Apparently these two are imported rarely, if ever. Unlike the vast majority of catfish, H. flavus is a diurnal species, and spends much of its time swimming in shoals in m...

The reason we have recommended the use of non-Tanganyikan cichlid hosts above is because a successful captive spawning using Tanganyikan cichlid species has never been recorded! This may be due to an evolutionary process that has been observed in the lake, in which many cichlid species appear to have learned to avoid S. multipunctata when breeding. This is similar to the rejection of alien eggs by the host species in brood-parasatising birds. Because no species of brood parasatising catfish occu...

Juveniles of this 'species' (probably a group of species - see 'distribution') are traded in large numbers but it's still uncommon to see adult specimens in the hobby suggesting their needs are not catered for often enough. This is a shame as when maintained properly they're hardy, long-lived and interesting aquarium residents. Other trade names include 'long-nosed' and 'banana' loach. Please note although certain that more than one species is being tr...
