Breeding Beginnings
The Bubble Eye Goldfish started in China centuries ago. Breeders selected fish with small eye sacs and bred them over generations. These sacs grew larger and more visible with each new group. The process took many years of careful breeding. This slow change made the Bubble Eye one of the most delicate goldfish types.
Early breeders focused on the fish’s eye sacs and body shape. They avoided fish with too large or damaged sacs. The goal was a balanced and healthy fish with the classic bubble eyes. This careful breeding helped the fish survive and thrive in home aquariums later.

Ideal Aquarium Size

Water Conditions
Maintain water temperature between 65 and 75 degrees Fahrenheit. Bubble Eyes prefer cooler water. Use a reliable heater and thermometer to keep stable temperatures.

Breeding Process
Start with healthy adult Bubble Eye Goldfish, usually around one year old. Place a male and female in a separate breeding tank. Keep the water temperature between 68 and 74 degrees Fahrenheit.
