Red And White Fantail Goldfish

Red and White Fantail Goldfish (Carassius auratus) displays the classic two-tone Sarassa-style red and white coloration on the egg-shaped Fantail body — vivid cherry-red patches on pure white, each individual with a unique distribution of the two colors. The clean contrast between the deep red and bright white is one of the most visually striking and traditional goldfish color combinations.

Feeding & Care Tip: Hikari Fancy Goldfish slow-sinking pellets are the ideal staple for fancy goldfish — the slow sink rate gives these slower-swimming varieties time to feed without gulping air at the surface, which can cause swim bladder problems. Sera Goldy Color Spirulina enhances red and orange coloration. Supplement 2–3× per week with Hikari Frozen or Freeze-Dried Baby Brine Shrimp or Hikari Frozen Daphnia. If keeping alongside slim-bodied goldfish, offer Hikari Goldfish floating pellets at the same time — the slim-bodied fish will take the floating food while the fancies feed at their preferred mid-water level, ensuring both types eat well.

The red-and-white two-tone pattern is one of the most prized in Japanese goldfish culture — historically associated with traditional koi and goldfish breeding where clean color boundaries and pure white grounds were considered marks of quality. In fancy goldfish, the pattern distribution is unpredictable — no two fish are identical.

Keep in groups of two or more. The red-and-white combination is most striking against a dark substrate and background which allows the bright white to glow. Compatible with all other fancy goldfish varieties. Fancy goldfish require a larger aquarium than most people expect — a minimum of 20 gallons for a single fish, with an additional 10 gallons per additional fish. A long, wide tank is preferable to a tall, narrow one — fancy goldfish spend most of their time in the lower half of the water column and benefit more from bottom area than height. Gentle filtration that moves the water without creating strong currents is ideal — the egg-shaped body of fancy goldfish makes them poor swimmers in turbulent water.

Goldfish are among the longest-lived aquarium fish — well-kept fancy goldfish regularly reach 10–15 years with excellent care. The investment in appropriate tank size, good filtration, and regular water changes is rewarded with a fish that becomes a genuine long-term companion. Filtration & Water Quality: Goldfish are high-waste fish that require robust filtration — significantly more than most tropical fish of equivalent size. A filter rated for at least twice the tank volume is recommended. Regular partial water changes of 25–30% weekly are essential. Despite their reputation as 'easy' fish, goldfish kept in under-filtered or overcrowded conditions decline quickly. Good filtration is the single most important factor in keeping goldfish healthy and long-lived.
