southern platyfish
Xiphophorus maculatus
The southern platy is a small freshwater fish with bright spots on its body. It lives in rivers and lakes of Central America and gives birth to live young.
The southern platy differs from close species in body shape and spot placement. It serves as food for larger fish and helps control the population of small aquatic organisms.
