The horadandia, green carplet, or glowlight carplet (Horadandia atukorali), is a species of very small (maximum {{convert|3|cm|abbr=on}} total length) freshwater ray-finned fish belonging to the family Danionidae. This species is found in slow-moving or still fresh and brackish water habitats in western Sri Lanka.{{FishBase |genus= Horadandia |species= atukorali| month = February | year = 2021}} 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.{{cite journal |author=Batuwita, S. |author2=de Silva, M. |author3=Edirisinghe, U. |year=2013 |title=A review of the danionine genera Rasboroides and Horadandia (Pisces: Cyprinidae), with description of a new species from Sri Lanka |journal=Ichthyological Exploration of Freshwaters |volume=4 |issue=2 |pages=121–140}}
