The Perugia-Kärpfling ( Limia perugiae ) is a freshwater fish from the genus Limia in the subfamily of the viviparous toothcarps . It is endemic to the south of the Dominican Republic on the island of Hispaniola .

features

Females usually reach a total length of 6 to 7 cm, a maximum of 8.5 cm, while males remain slightly smaller and reach a maximum of 7 cm. The body is high and slightly flattened on the sides. The basic color of both sexes is gray-brown. Only dominant males show a blue sheen on the sides of the body. The breast is whitish. The dorsal fin is enlarged and has a black-white-yellowish pattern. Females show a transverse band consisting of 5 to 6 vertical stripes that extends from the rear edge of the gill cover to the base of the caudal fin. The belly is whitish, the fins are colorless; the dorsal fin shows the typical spot for the genus. Otherwise the dorsal fin is black, the caudal fin is yellow and black-brown edged.

habitat

The two Viennese aquarium friends Lechner and Radda examined different habitats in 1978 and found Limia perugiae in crystal clear water with temperatures between 24 and 30 ° C, with a neutral pH value and an electrical conductivity of up to 2000 mS / cm. They found the largest individuals in karst springs.

Reproduction

Limia perugiae is viviparous. After a development time of around 24 days, adult females release up to 100 young fish that are around 7 millimeters long.

Systematics

Limia perugiae was described as Platypoecilius perugiae on the basis of a single specimen from a small river in the San Francisco Mountains in the Dominican part of the Caribbean island of Hispaniola . The very poorly preserved holotype is in the National Museum of Natural History under catalog number USNM 53278 . The species name is a dedication in honor of the Italian ichthyologist Albert Perugia.

Fin formula : D 9, P 15, V 6.

Importance to humans

Lechner and Radda brought the first Limia perugiae to Europe in 1978 . Since then, they have been widely used among specialist aquarists. They play no role in the aquarium fish trade.
