Guppy

The guppy is a small freshwater fish native to northeastern South America and nearby Caribbean islands, now widely kept in aquariums. Males often show bright colors and patterned fins, while females are usually larger and less ornate. Females give birth to live young. Wild and selectively bred forms differ markedly in appearance. Guppies feed on small aquatic organisms and other available foods, often near the surface. Their adaptable habits have contributed to introductions beyond the native range.
