Red Comet Goldfish

Red Comet Goldfish is a vibrant and active variety of goldfish, known for its bright red colouration and long, flowing tail. Our comet goldfish for sale are hardy coldwater fish that can grow to 20cm or more, making them a favourite for outdoor ponds and large aquariums.

Location

The comet was developed in the United States in the late 1800s from goldfish first bred in China, and it is now one of the most popular pond fish. They thrive in a variety of freshwater habitats, including ponds and large aquariums, as long as the water conditions are maintained well.

Diet

As omnivores, Red Comet Goldfish enjoy a varied diet. They readily accept high quality goldfish flakes, pellets, and occasional live or frozen foods such as bloodworms and daphnia. Offering a balanced diet is essential to ensure their health and vibrant colour.

Care

As coldwater fish, comets do not need a heater and are comfortable between 10 and 22°C, with a pH of 7 to 8. Regular water changes and good filtration are important to maintain optimal water conditions, as these fish produce plenty of waste and are sensitive to poor water quality.

Habitat

Red Comet Goldfish require ample swimming space in a pond or a large aquarium. They thrive in environments with gentle filtration, plants, and plenty of room to swim. Since they are fast swimmers, it’s best to house them with other peaceful coldwater fish that can keep up with their energetic movements.

Breeding

Breeding Red Comet Goldfish is achievable with the proper conditions, and they often spawn in ponds in spring. During the breeding season, males chase females, and the fry can be raised in a separate tank.
