Apistogramma viejita is a dwarf cichlid in the subfamily Geophaginae. It is a benthopelagic freshwater fish that lives in the Meta River and the Orinoco River in Colombia. They grow up to 4.6 cm in standard length. The A. viejita you find most often sold in fish stores is not actually A. viejita at all, but instead a separate species, A. macmasteri. If you have purchased your fish from a local fish store, you should first assume it is A. macmasteri and not viejita, and seek help from an expert for identification.
