Overview Family: Carassius auratus Fancy Goldfish are domesticated variants of wild carp, admired for their unique body shapes, flowing fins, & gentle personalities. Unlike common goldfish, fancies thrive in well-filtered aquariums, rather than ponds, with warmer temperatures & plenty of swimming space. They are social fish that do well in groups, but their delicate fins require a calm environment free of sharp décor & aggressive tank mates. Fancy Goldfish are messy eaters, so strong filtration & regular maintenance are key to keeping their water clean & healthy. Recommended Tank Size: A minimum of 80 litres Fancy Goldfish are social & peaceful but require ample space & stable conditions to thrive. Providing smooth décor & strong filtration helps reduce stress & fin damage. Average Adult Size: Body length: 15–20cm Fancy Goldfish grow slowly but steadily, reaching adult size over 12–24 months with proper care. Water Parameters: pH: 6.5–7.5 Alkalinity: 4–10 KH General Hardness (GH): 6–12 Temperature: 18–24°C Food: High-quality goldfish pellets or gel food designed for slow-swimming breeds Supplement with blanched veggies: zucchini, spinach, peas (shelled) Occasional treats: bloodworms, brine shrimp, or daphnia Feed 1–2 small meals daily
