History, Habitat, and Care of Goldfish

Goldfish, the hero of childhood fairy tales, still fascinates and seems magical, able to grant three wishes. These remarkable fish belong to the carp family and have been selectively bred for centuries. Their wild relatives still inhabit rivers and lakes in East Asia.

All modern goldfish originate from the Chinese crucian carp (Carassius auratus) living in freshwater. Selective breeding began around the 10th century when the Chinese emperor wanted to breed uniquely colored fish. The first goldfish were yellow and purple, considered symbols of prosperity and abundance.

Wild goldfish continue to live in the calm waters of China, Korea, and Japan. Studies show that wild crucian carp populations remain stable despite environmental pressures. Goldfish prefer staying in one place and are found in various freshwater habitats, including lakes, old ponds, and slow-flowing rivers.

Aquatic plants and shelters are essential for their habitat. They feed on algae and avoid predators. Water temperatures in their natural environment range from 4 to 30 °C, making them very resilient.

For keeping goldfish at home:

— Aquarium size of at least 50 liters per fish;

— Clean, filtered water with regular changes;

— Water temperature 18–24 °C;

— Adequate plants and hiding spots for feeding and protection.

In the wild, goldfish live 10–15 years; under good conditions, up to 20 years. Their diet includes algae, small invertebrates, and insect larvae. Goldfish adapt successfully to various living conditions.
