The Mixed Oranda Goldfish ( $Carassius\ auratus$ ) is a popular fancy goldfish, recognized by its large, raspberry-like cranial growth (wen) and long, flowing fins. Orandas are social, active, high-waste producing fish that require a large, well-filtered tank, smooth decor, and a specialized sinking diet to combat common digestive issues.

Appearance and Sexual Differences

Short Description: A heavy, rounded, or ovoid-bodied goldfish with long, paired fins and a large, fleshy, dome-shaped cranial growth (wen) on the head. Their large body size and abundant waste make them demanding on water quality.
Coloration: Colors vary widely (Red, Calico, Black, Blue, etc.). Males develop small white tubercles (breeding stars) on the gill plates and pectoral fins during spawning season. Females are visibly larger and more rounded/plump when carrying eggs.
Fins: Long, flowing fins (double caudal fin). The large wen can sometimes compromise their eyesight and is prone to infection.
Behavior: A peaceful and docile social fish. They are voracious, non-fussy eaters and produce a heavy bioload. Their unique body shape makes them poor swimmers and susceptible to swim bladder disorder.

Tank Requirements and Water Parameters

Minimum Tank Size: 20 gallons (75 liters) minimum for the first fish, plus 10 gallons for each additional fish. A 55-gallon tank is ideal for a small, healthy school.
Schooling: Highly social; best kept in groups of 2 or more of similar slow-moving fancy varieties (e.g., Ryukin, Fantail, Black Moor).
Temperature: Cold/Cool Water Range: $65^\circ$ – $75^\circ\text{F}\ (18^\circ$ – $24^\circ\mathrm{C})$ . Avoid tropical temperatures, which shorten their lifespan.
pH Level: Highly adaptable: 6.0 to 8.0. Requires robust filtration (rated 3–5 times the tank volume) and large, frequent water changes (25–30% weekly) to control the high waste and keep nitrates low. Gentle water flow is needed to avoid stressing their swimming.
Aquascape: Requires smooth, fine substrate (sand is best) to prevent injury to their sensitive mouth and wen. All decor must be smooth and dull-edged. Provide ample open swimming space. Hardy plants may be used, but secure them well as Orandas may nibble or uproot them.

Diet and Feeding

The Mixed Oranda is an omnivore, susceptible to bloat and constipation.

Staple Diet: High-quality sinking goldfish pellets or granules (sinking food is vital to prevent gulping air). Focus on diets rich in plant matter and color enhancers.
Supplementation: A diet rich in fiber is mandatory. Offer blanched fresh vegetables (shelled peas, zucchini, spinach) regularly to aid digestion. Soaked gel foods (Repashy) are also excellent.
Schedule: Feed small portions once or twice daily. Never overfeed. Fast the fish one day a week to aid digestion. Soaking dry food is strongly recommended.

Compatibility

Caution: Slow swimmers and poor competitors for food. Do not keep with fast-swimming fish (Danios, Barbs) or known fin-nippers. Monitor the wen for signs of trauma or infection (from water quality issues).
Good Tank Mates: Only other slow-moving Fancy Goldfish (e.g., Ryukin, Lionheads, Fantails, Pearlscales). Larger, peaceful bottom-dwellers like large Mystery Snails can also be suitable.
