Adonis tetra (Lepidarchus adonis)
The Adonis tetra (Lepidarchus adonis) also known as the jellybean tetra, is a very small African fish of the family Alestidae.[ It is the only member of its genus.
Lepidarchus adonis is native to freshwater habitats near the Atlantic coast in Ghana, Sierra Leone, and Côte d’Ivoire.
The Adonis tetra can reach 2.1 cm long, smaller than the neon tetra, and is one of the smallest fish normally kept in aquaria.
The IUCN red list lists the Adonis tetra as being vulnerable (2010). There is considerable cause for concern because of the increasing levels of pollution in the waterways it inhabits.
