Goldfish for Sale: Fancy and Comet Goldfish

No. Goldfish are coldwater fish and are comfortable between 10 and 22°C, so a heater is not needed in a tank kept indoors.

Yes. Comet goldfish and shubunkins are ideal pond fish and cope with UK winters as long as the pond is deep enough not to freeze solid. Fancy goldfish are slower swimmers and are best kept in an indoor tank.

Comet goldfish can grow to 20cm or more given space, especially in a pond. Fancy goldfish such as the black moor and pearlscale goldfish have rounder bodies and stay more compact.

Goldfish grow large and produce a lot of waste, so give them plenty of water and a strong filter. A pair of fancy goldfish needs a tank of at least 100 litres, while comets do best in a large tank or a pond.

With good care, goldfish commonly live for 10 to 15 years, and pond goldfish can live even longer.

Yes. Goldfish are hardy and forgiving, which makes them a great first fish, as long as they have enough space and good filtration. Always treat tap water with a conditioner first.

Comet goldfish have slim, streamlined bodies built for speed and suit ponds. Fancy goldfish have short, rounded bodies, often with long flowing fins or features such as the raised scales of the pearlscale, and are a little more delicate.

Feed a good quality goldfish flake or sinking pellet once or twice a day, with blanched peas or other vegetables as an occasional treat. Sinking food helps fancy goldfish avoid gulping air at the surface.

We do not recommend it. Goldfish prefer cooler water than tropical fish, and comets grow large enough to bully or eat small tropical species.
