Cheap, bombproof and long-lived, it is a superb pond and big-tank fish, but be warned: it grows large, commonly reaching 25–30 cm and living for decades, so it needs real space.\u003c\/p\u003e \u003ch2\u003eNatural Habitat\u003c\/h2\u003e \u003cp\u003eCarassius auratus is a domesticated form descended from wild East Asian carp of slow rivers, lakes and ponds. It is a temperate, coldwater fish adapted to still and gently flowing waters that vary widely in temperature through the seasons, with plenty of vegetation and a soft, silty bottom to root through.\u003c\/p\u003e \u003ch2\u003eAppearance\u003c\/h2\u003e \u003cp\u003eThe single-tailed common goldfish has a streamlined, torpedo-shaped body built for steady, powerful swimming.

Provide a minimum of around 150 L for a single fish, with much larger tanks or a pond for a group — it is genuinely best suited to pond life. Keep it cool at 10–24 °C, pH 6.5–8.5 and moderately hard to hard water.

In spring, a rise in temperature triggers spawning, with males chasing gravid females to release adhesive eggs among plants or spawning mops. Eggs receive no parental care and hatch in a few days; fry are reared on infusoria and fine foods.
