Alestopetersius brichardiCherry Red Congo Tetra
Alestidae · Poll, 1967
This species is sometimes traded as 'cherry red Congo tetra' or 'super red Congo tetra' and has also been referred to using the misapplied names Alestopetersius nigropterus (a valid congener) and A. ansorgii (a synonym of Nannopetersius ansorgii).

Alestopetersius caudalisYellow-Tailed Congo Tetra
Alestidae · Boulenger, 1899
This species is also traded as 'yellow-finned', 'yellowtail' or 'blue Congo' tetra and is occasionally bred on a commercial basis, although not on a scale comparable to its better-known relative Phenacogrammus interruptus. No recent key to the genus exists but based on Géry (1977) and images in Mbimbi Mayi Munene and Stiassny (2012) it can be told apart from congeners by a combination of: extended median caudal-fin rays in adult males; absence of prominent dar...

Alestopetersius nigropterusAfrican Rainbow Tetra
Alestidae · Poll, 1967
This fish is normally traded as A. nigropterus or A. cf. ansorgii although neither appears to be its correct name meaning it remains unidentified at present. A. nigropterus is a valid congener that is not in the aquarium trade with little to no export from Lake Mai-Ndombe, to which it is endemic, while A. ansorgii is a synonym of Nannopetersius ansorgii.

'Barbus' candens
Cyprinidae · Nichols & Griscom, 1917
'B.' candens is not really suitable for most community aquaria as it has something of a shy, retiring nature and may be intimidated or outcompeted for food by larger/more boisterous tankmates. Choose similarly-sized, peaceful African species such as 'B.' jae, Aplocheilichthys spp., Ladigesia roloffi or Lepidarchus adonis. We suspect it will also do ok with many small South American characins, Otocinclus or smaller Corydoras catfish and other cyprinids like Trigonostigma or Boraras species.

'Barbus' fasciolatusAfrican Banded Barb
Cyprinidae · Günther, 1868
For many years this species was imported and sold as Barbus/Barbodes barilioides, now recognised as a junior synonym of 'B.' fasciolatus, and is sometimes called the Blue Banded or Angola Barb. It's an exceptionally attractive little fish when in good condition but like all African barbs is quite rare in the hobby due to sporadic exports from the countries in which it is found. Distinguishing features include 25-30 late...

'Barbus' holotaeniaSpotscale Barb
Cyprinidae · Boulenger, 1904
This species is native to Central West Africa where it is principally found in the great Ogooué and Congo River systems. It therefore has an extensive range and has been recorded at numerous localities right across the Democratic Republic of Congo (DRC) from the Ituri River in the far east of the country to the Luki River basin in the extreme west. The Congo River appears to represent the southernmost limit of its range as a...

'Barbus' hulstaertiAfrican Butterfly Barb
Cyprinidae · Poll, 1945
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.

Clypeobarbus congicusCongo Barb
Cyprinidae · Boulenger, 1899
Clypeobarbus was originally put forward as a subgenus of Barbus by Fowler in 1936 on the basis that member species possessed a midlateral row of enlarged, shield-like scales but he only included the type species 'Barbus' kemoensis (now a junior synonym of Clypeobarbus pleuropholis) in the group. Subsequent work by Poll and Lambert (1961), Jubb (1965) and Skelton (1993) resulted in several additional species being placed into the grouping although it appears that little of this work was widely-recognised until the recent study was published.

Congochromis sabinae
Cichlidae · Lamboj, 2005
This species was present in the hobby for some time prior to being officially described and the spectacular red fish first exported by Pierre Brichard in the 1960s appears to be a regional form of it. It was also known variously as Nanochromis sp. 'Bamanja', N. sp. 'Genema', N. sp. 'Makoua' and N. sp. Bloody Mary' prior to description, and continues to be mislabelled as N. squamiceps on trade lists. Diagnosis of C. sabinae is possible via a combination of c...
Ctenopoma acutirostreLeopard Bushfish
Anabantidae · Pellegrin, 1899
An ideal species for the newcomer to 'oddballs'. It is exceptionally hardy, long-lived (it can survive for over 15 years when cared for properly) and exhibits some interesting behaviour. It appears to have evolved convergently with leaf fish of the genera Polycentrus and Monocirrhus (they're not closely related). All these species mimic leaves and other aquatic debris to assist them in hunting their prey. If you add live food to its tank, you will see the typical stalking behaviou...

Aphyosemion cognatumRed-Spotted Lyretail
Nothobranchiidae · Meinken, 1951
The type material was derived from a commercial shipment of fishes from Leopoldville, now Kinshasa, Democratic Republic of Congo, and presumed to have been collected in the vicinity. The precise extent of its distribution unknown but appears extensive in the middle and lower Congo regions, with specimen collected from Lac Fwa (Sankuru River drainage, a Congo River tributary), many hundreds of kilometres west of Kinshasa, identified as belonging to this species.

Aphyosemion decorseiDecorse's Lyretail
Nothobranchiidae · Pellegrin, 1904
Type locality is the settlement of Bessou, Lobaye prefecture, Central African Republic, which lies within the Ubangi (also spelled Oubangui) River basin. The Ubangi is a major tributary of the Congo River and this species appears restricted to its middle section and thus probably extends into northern Republic of Congo and Democratic Republic of Congo.

Epiplatys mesogramma
Nothobranchiidae · Huber, 1980
Endemic to the Ubangi (also spelled Oubangui) River drainage in southwestern Central African Republic with type locality given as 'Small stream along Mbaiki-Mongoumba road, south of Bangui, 3°55'N, 18°10'E, Central African Republic'. The Ubangi is is the largest right-ba...
