Basic care information: A single-tailed goldfish variety known for its long, flowing tail and streamlined body. Comets are active swimmers and require more open swimming space than many fancy goldfish. Provide strong biological filtration, good oxygenation, and regular water changes. Maintain clean, stable water around 18–24°C with a pH of approximately 6.0–8.0. Keep with other single-tailed goldfish of similar size and swimming ability, and avoid overcrowding. Goldfish can grow considerably larger than their typical aquarium size when provided with sufficient space and care.
