Threespot barb (Enteromius trimaculatus) is a species of cyprinid fish in the large genus Enteromius . It has a wide distribution in sub-Saharan Africa from the Congo Basin east to the Indian Ocean coast of Tanzania and south to KwaZulu Natal in South Africa. [3] It occurs in shallow water around river inflows or near swampy areas. It is a habitat generalist and also hardy, but it prefers vegetated areas. It feeds on insects and other small animals. It is often caught for use as bait by anglers fishing for tigerfish. It breeds during the summer rainy season when shoals of fertile adults migrate upstream when the rivers are in spate following rain. A single females may produce as many as 8,000 eggs. [4]

In biology, a species ( ) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clone is potentially a microspecies.

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
