General Description: Comets are a great beginner goldfish, as long as proper care and conditions are provided. They have been a mainstay in the hobby for many years, having been the result of selective breeding in China. Comets differ from common goldfish, as they have a long, flowing, forked tail and are gold or orange in color, and can sometimes have black markings. When ready to spawn, males will develop notches on their head called tubercles, and females will appear more plump. Comets may appear small at fish stores, but will ultimately require a large aquarium or pond as they can exceed 12 inches over time.
Diet Requirements: Comet goldfish are omnivores and will accept most foods that are offered. Some options include goldfish specific flake or pellets, brine shrimp, blood worms, and various plant matter.
Care Requirements: Goldfish prefer cool water, usually ranging from 60-70F, but can tolerate a much wider range especially in outdoor ponds. Due to being a coldwater species it is best to keep them with other comets or related goldfish varieties in an outdoor pond or 75 gallon or larger aquarium for overwintering indoors. Comets produce a large amount of waste, so good filtration and oxygenation are necessary. Comet goldfish are a long-lived species and can live for more than ten years in captivity. Floating plants are best for aquariums or ponds with comets, as they have a tendency to sift through gravel and uproot species. Comets are very peaceful and sociable fish. Recommended water conditions, 36-90° F, KH 2-12, pH 6.8-7.2.
