Perugia's limia (Limia perugiae) is a poeciliid fish endemic to the Caribbean island of Hispaniola. It is one of the most widespread species in the Limia genus, inhabiting waters ranging from fresh to hypersaline. Unlike most Limia species, L. perugiae is omnivorous. Dominant males are especially colorful. Females give birth to live young.
