Some eminent authors believe this species to be a geographical variant of the highly variable congener A. stuartgranti rather than a distinct taxon but since most popular resources continue to view it as valid we also list it here. At Masinje it has been observed to show a distinct preference for rocky caves and crevices in relatively shallow (3-6 metres deep) water. This is in contrast to most other members of the genus, which tend to forage over sand, but similar to behaviour seen in A. jacobfreibergi.

This was one of the first Aulonocara spp. to enter the hobby and its popularity has endured. It's known by several other vernacular names including 'Freiberg's peacock', 'fairy cichlid' and 'African butterfly' as well as the erroneous 'scientific' names Trematocranus trevori, T. jacobfreigbergi and T. regina. A naturally-occurring, yellowish form from Undu reef, Tanzania is often referred to as 'lemon jake'. It can be told apart from most other members of the genus by the broad, pale distal margins in the dorsal, anal and caudal fins, more deeply-forked caudal fin and larger adult size.

This species exists in two distinctive phenotypes, with male individuals from West reef and Eccles reef possessing a bright yellow stripe of colour running from the tip of the snout over the anterior portion of the dorsal surface and along the distal margin of the dorsal fin. This form is commonly referred to as 'sulphurhead' or 'sulfurhead' in the aquarium hobby. At Kande Island males exhibit a similar overall colour patterm but the dorsal stripe is whitish in colour and both males and females possess an enlarged lower pharyngeal bone. This population was described...

This species is much rare in the hobby than its congener A. stigmatias, presumably a reflection of its more remote, restricted natural range. The red pigmentation on the body can vary in both extent and intensity, and apparently begins to fade when the fish have been maintained in aquaria for a period.

It's most similar to A. riesei but can be told apart by its more-elongate body (depth 4-5 times, vs. 3.1-3.5 times, in SL), live body colour (silvery yellow, vs. red) and suborbital bone structure (almost complete, vs. reduced). The third species, A. lindeae, is quite different posses...

Like most badids this species is poorly documented and has yet to find significant popularity in the aquarium hobby. It is easily confused with B. blosyrus at first glance as the body patterning of the two is almost identical but can be distinguished by its slightly larger adult size, noticeably shorter jaw profile and some other, mostly internal, meristic characters. Prior to 2002 the family Badidae inc...

Like most badids this species is poorly documented and has yet to find significant popularity in the aquarium hobby. It is easily confused with B. assamensis at first glance as the body patterning of the two is almost identical but can be distinguished by its slightly smaller adult size, noticeably elongated, more well-developed jaw profile and some other, mostly internal, meristic characters.

Like most badids this species is poorly documented and has yet to find significant popularity in the aquarium hobby. It is arguably the most attractive member of the genus and we hope to see it more widely available; the fish in our images representing what is thought to be the only batch exported from Myanmar to date. It is most closely related...

B. ruber is among the better known Badis species in the aquarium hobby with trade names including 'Burmese badis' and 'red badis'. It was referred as Badis badis burmicanus for a number of years and will be seen labelled as such in older literature. Among congeners it is most easily confused with...

Like most badids this species is poorly documented and has yet to find significant popularity in the aquarium hobby; to date it has only been exported in very limited numbers. It was for a number of years known as Badis badis siamensis and will be seen labelled as such in older literature. Within the genus it is most easily confused with B. khwae and B. ruber but can be identified by the flank patterning which consists of rows of horizontally-arranged dark markings. In B. ruber these appear mor...

There is considerable confusion surrounding the identity of B. bagarius with its name having been widely applied to a relatively small species that is said to reach only 200 mm SL and considered to be common in northern India and much of Indochina.

May also be seen on sale under the trade names 'Bala shark' or 'tricolor shark minnow' and perhaps among the most commonly-encountered ornamental fish species. It is unfortunate that the vast majority of those traded are juveniles and tend to come supplied with little to no information provided regarding their potential size and requirements, a fairly ironic situation given the apparently precarious status of wild populations.

This species is also known by the alternative names 'green' or 'Chinese' barb. The natural 'green' form is an infrequent find in the aquarium trade whereas the selectively-bred 'golden' variant is farmed in huge numbers and is among the most popular of freshwater aquarium fish. The latter was first produced in the 1960s and is now so ubiquitous that many hobbyists are initially unaware that it is not the natural form.

This species is still very rare in the hobby although it has built up something of a following among enthusiasts of planted 'nano' aquaria and you may see it on sale under the trade names of 'dwarf amber/ember barb'. Its small adult size evolved via a process known as miniaturisation characterised by sexually mature adults with a significantly reduced size of less than 20mm SL. Among bony fishes cyprinids are one of the few groups in which this phenomenon occurs repeated...

This is one of two species sold with the common/trade name of "tinfoil barb", the other being the more widely-recognised B. schwanenfeldii. Despite this it appears that B. altus is just as widely available as B. schwanenfeldii and in many cases is seen on sale more regularly. Unfortunately both are usually offered at a small size (usually around 2 - 3"/5 - 7.5cm) with little to no information regarding the eventual size of the fish. Although B. altus is the ...

The genus Barbonymus was erected by Kottelat in 1999 and contains former members of Barbodes from southeast Asia. The type species is B. schwanenfeldii and currently there exist only three other representatives; B. altus, B. collingwoodii and B. gonionotus. The latter two are rare in the hobby although an SF member has kept B. gonionotus in the past so they are worth looking out for if you harbour an...

This is one of two species traded under the vernacular name 'tinfoil barb', the other being the less well-known congener B. altus. Despite this it appears that B. altus is just as widely available as B. schwanefeldii and in many cases is seen on sale more regularly. Unfortunately both are usually offered at a small size (usually around 50 - 75 mm) with little to no information regarding the eventual size of the fish.

Two closely-related species are also found in the Congo basin and infrequently seen in the trade. 'B.' candens has been collected northeast of the range of 'B.' hulstaerti around the city of Kisangani (formerly Stanleyville) and nearby town of Yangambi. It can be distinguished from 'B.' hulstaerti by its paler body colouration, smaller dark markings on the body and red ventral and anal fins in males. 'B.' papillo is known only from its type locality close to the eastern town of Kindu between the Lualaba and Lomami rivers. It has an elongated central body marking and males possess black dorsal, ventral and anal fins.

Although gregarious by nature it is a shoaling rather than schooling species which develops a distinct pecking order between males. It should ideally be maintained in a group of 8 or more but the tank must be of a sufficient size which will allow weaker individuals some respite from dominant conspecifics and decorated in such a way that many broken lines of sight are provided. Conversely if kept singly, in a very small group or in cramped conditions it can become withdrawn and subdominant fish may be bullied incessantly.

Prior to its description this species was typically identified as the congener B. canarensis in the ornamental trade. It can be distinguished from congeners by the following combination of characters: uni...
