Comet 12cm

Comet

Comet goldfish are usually the first fish an aquarist keeps when they enter this hobby. Goldfish make for a fantastic ornamental fish and have such a rich history that they carry. The comet style of goldfish was developed in America and is now recognised worldwide for its elongated body shape, long tail, and stunning colours.

Comet goldfish come in a range of different colours however, the most common would be the classic orange. These bright colour is often contrasted by a white belly. For aquarists who simply do not have the space to keep koi, the comet is the perfect alternative for this issue. They get big enough without getting absolutely monstrous. These would be a perfect pond addition and will really stand out with their vibrancy, especially under natural sunlight.

Breeding these comet goldfish is not common in the home aquarium, but in an outdoor pond with plant cover, it should happen naturally. The females are egg scatterers and as long as there is enough cover and vegetation in the pond, there is a high chance that the offspring will survive. Though there are no immediate distinguishing factors between males and females, females tend to be rounder.

Tank Recommendations for Comet

Comet goldfish can easily reach an excess of 20 cm, it is best to keep these fish in a large aquarium. The minimum volume should be around 350 litres for a full-grown fish. This ensures that there is enough space for swimming and a large enough volume for this generally messy fish. A sandy substrate will be great as goldfish often sift through the sand in search of food, fine leafed plants will easily become a meal. However, species like anubias will be fine to keep.

Suitable Tank Buddies

Comets are a great fish because they are not aggressive in the slightest and can be kept with a range of tank mates. Common tank mates they can be kept with are active and small, coldwater-tolerant fish. The goldfish, however, might eat fry produced by these smaller fish, however, they will be perfectly fine with adults. Fin-nipping species, however, should be avoided entirely as they will make short work of the flowing fins of the goldfish.

Usually Compatible

Other goldfish strains, danios, koi, and similar coldwater species.

Sometimes Compatible

Very small and slow-moving fish may potentially become a meal such as white cloud minnows.

Rarely Compatible

Discus, neon tetras, rams, oscars, and other high-end tropical or aggressive species.

Feeding your Comet

These goldfish would be an incredibly fun fish to feed because they will really set off a feeding frenzy when in a school. Giving a good quality pellet food would be the easiest and most nutritional option for these goldfish. They can also be fed green matter, like blanched vegetables, for added variation to the diet.
