The redeye barb or Beira barb (Enteromius radiatus), is a widespread African species of freshwater cyprinid fish which is found from Uganda south to the Limpopo River and Incomati River systems in South Africa. [1]
The redeye barb lives and feeds on the bottom as well as in the middle of the water column and at the surface. It prefers marginal vegetation in rivers but also occurs in marshes and among the fringing vegetation of lakes. In Eswatini, redeye barbs have been recorded in rock pools in the Komati River, in Lake Malawi it has been recorded where the shoreline is rocky, while in the Lake Rukwa drainage system it occurs in rivers which feed the lake and associated smaller waterbodies and in Lake Chiuta it has been reported as reasonably common in the lake and in slower flowing stretches of the inflow streams. In some drainage systems the redeye barb undertakes seasonal migratory movements. The redeye barb is crepuscular and prefers subdued light but it is also active during the night. Its main prey is invertebrates. [1]
There were previously three recognised subspecies but one of these has now been recognised as a separate species Enteromius profundus and the other two are now considered to be morphs of a single monotypic but polymorphic species [2]
The redeye barb is a small barb which has salmon or orange-tinted fins, edged with black and a conspicuous red upper half to the eye. [3] It is countershaded with specimens from Lake Malawi having the dorsal surface coloured olive contrasting with the belly silvery white belly, these are separated by a dark lateral stripe which extends from the caudal fin to the snout in the majority of specimens, although in some this may be rather indistinct. The scales lying immediately above this lateral stripe are heavily spotted creating faint longitudinal stripes, markings which become more obvious in preserved specimens. [4] The head is covered in lines of sensory pits which are apparent when a specimen is examined using a handlens. [2] The meristic data is that there are 3 spines in the dorsal fin and 9 soft rays while the anal fin has 3 spines and 6 soft rays. The maximum size is 12.0 cm standard length. [5]
The redeye bass, redeye, or Coosa bass is a species of freshwater fish in the sunfish family (Centrarchidae) native to the Coosa River system of Georgia, Alabama. The waters it is normally found in are cool streams and rivers in the foothills of mountains.
The tinfoil barb is a tropical Southeast Asian freshwater fish of the family Cyprinidae. This species was originally described as Barbus schwanenfeldii by Pieter Bleeker in 1853, and has also been placed in the genera Barbodes and Puntius. The specific epithet is frequently misspelled schwanefeldii.
The tiger barb or Sumatra barb, is a species of tropical cyprinid fish. The natural geographic range reportedly extends throughout the Malay Peninsula, Sumatra and Borneo in Indonesia, with unsubstantiated sightings reported in Cambodia. Tiger barbs are also found in many other parts of Asia, and with little reliable collection data over long periods of time, definite conclusions about their natural geographic range versus established introductions are difficult. Tiger barbs may sometimes be confused with Puntigrus anchisporus, Puntigrus navjotsodhii, or Puntigrus partipentazona, which are similar in appearance, the only differences being the slightly different stripe pattern and the number of scales these fish have.
The shoal bass is a species of freshwater fish in the sunfish family (Centrarchidae) of order Perciformes. One of the black basses, it is native to waters in Florida and Georgia. It is also occasionally found in rivers and streams of East Alabama where it has been declared an endangered species and cannot legally be kept if caught by fishermen. Of typical size for a black bass, M. cataractae reaches a maximum recorded length of 24 inches (61 cm) and a maximum published weight of 8 pounds, 12 ounces.
The roach, or rutilus roach, also known as the common roach, is a fresh- and brackish-water fish of the family Cyprinidae, native to most of Europe and western Asia. Fish called roach can be any species of the genera Rutilus and Hesperoleucus, depending on locality. The plural of the term is also roach.
Enteromius litamba is a ray-finned fish species in the family Cyprinidae. It has long been placed in Barbus, the "wastebin genus" for barbs, by default, and this is still being done by the IUCN. However, the species is increasingly being restored by some taxonomists to the related yellowfish genus Labeobarbus, others place it in the genus Enteromius. It is presumably hexaploid like the other yellowfish.
The Odessa barb is a species of cyprinid fish known from Central Myanmar, where it is known to occur in an artificial pond above the Anisakan Falls and also from the lower Chindwin River. For many years it has been known to the aquarium hobby, where it has frequently been confused with the less colourful ticto barb), but it was only described scientifically in 2008.
The longnose shiner is a species of ray-finned fish in the genus Notropis.
Enteromius ablabes is a species of ray-finned fish in the genus Enteromius. It occurs in West Africa from the Sahel to the coast between Guinea and Nigeria, south to the central Congo Basin. The relationship of E. ablabes to other Enteromius is uncertain. Tsigenopoulos et al. (2002) found it to be sister to E. macrops. Yang et al. (2015) using the same sequence found it to be sister to E. anema, and Hayes et al. (2017) found the Tsigenopoulos et al. specimen to be sister to E. anema + E. cf. guildi and newly sequenced specimens from Guinea to be sister to be in a clade with a specimen of E. punctitaeniatusand that clade sister to E. bigornei and E. foutensis. The Tsigenopoulos et al. specimen is from Ivory Coast, but a catalog number is not provided to check identity. Enteromius punctiteniatus is a species very similar in appearance to E. ablabes, differing by having 9 circumpeduncular scales vs. 12. Enteromius ablabes is likely polymorphic with one species already described from within it. This description conforms to the current hypothesis on the identity of E. ablabes; however, the species will need to be examined in greater detail to determine if there are multiple species present.
Enteromius baudoni is a species of tropical cyprinid freshwater fish from Central and Western Africa. It is found in western Africa, in the river basins of the Chad Basin, the Volta basin, the Niger River basin, the Gambia River basin, the Senegal River basin, the Sassandra River basin, and the Bandama River basin. In central Africa, it is found in the Ubangui River ecosystem. It typically inhabits tropical freshwater ecosystems between 24 and 26 °C. It was originally described by Belgian-British zoologist George Albert Boulenger as Barbus baudoni in 1918, and the holotype, collected from Bangui, Central African Republic, is stored at the Muséum national d’Histoire naturelle in Paris. The species was originally classified in the Barbus genus, but was reclassified as belonging to the Enteromius genus in 2015 after examining extensive taxon, geographical, and genomic sampling of the species in the family Cyprinidae.
The chubbyhead barb is a species of freshwater ray-finned fish in the genus Enteromius. The fish is found throughout South Africa in a variety of aquatic environments. The species is notable for its two breeding seasons, which allows it to flourish despite a short lifespan.
The linespotted Ufipa barb is a rare species African freshwater cyprinid fish. It is only known from a small affluent of the Lukinda in the Lake Mweru system of the Congo River basin, in D.R. Congo.
Jae barb or Dja barb,, is a species of cyprinid fish which like other sub-Saharan "barbs" was formerly placed in the genus Barbus, it has now been reallocated to Enteromius.
The redspot barb is a species of freshwater cyprinid fish found in East Africa. It is named for the large, orange-red spot found on each operculum.
The broadband barb is a species of cyprinid fish in the genus Enteromius. It is found in Lake Malawi and the lower Zambezi, Pungwe River and Buzi River. The broadband barb is exploited for human consumption and for the aquarium trade.

It is, along with about 17 other species of darters, is native to the lakes and streams of Iowa.
The bluntnose darter is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is found in eastern North America where it is found in slower moving and still waters.
There are two major sources of fish in Uganda; one is from aquaculture, the other from fishing in rivers and lakes. Different types of fish flourish in different water sources. The waters of Uganda contain an impressive array of fish species—over 90 in all. This count does not include the Haplochromis complex, which itself is made up of more than 200 species.
Enteromius is a genus of small to medium-sized cyprinid fish native to tropical Africa. Most species were placed in the genus Barbus.
Capoeta razii, is a newly described species of freshwater cyprinid fish occurring mainly in southern Caspian Sea basin, Iran. This species was mistakenly reported by many authors as Capoeta gracilis in northern Iranian regions. It was first reported to be different from Capoeta gracilis by Levin et al. (2012).
