Green carplet
The horadandia, green carplet, or glowlight carplet ("Horadandia atukorali"), is a species of very small (maximum total length) cyprinid fish that is found in slow-moving or still fresh and brackish water habitats in western Sri Lanka. Earlier thought to be a monotypic genus with the single species found in both Sri Lanka and India, an analysis published in 2013 showed that the Indian population should be recognized as a separate species, "Horadandia brittani".
