Bellotti's Pearlfish

Austrolebias bellottii is one of the larger and more widely distributed Austrolebias, found in temporary pools across the La Plata basin in Argentina, Uruguay, and southern Brazil. Males display a deep blue body sprinkled with silver-white spots and vivid blue-edged fins, while females are attractively mottled in brown. Its greater size and relatively robust constitution make it one of the better entry-point annual South American killifish.
