The Carassius Auratus - Shubunkin Goldfish (Small) is a high-performance biological asset, engineered for aerodynamic velocity and complex chromatic signaling in technical freshwater systems. Characterized by a "calico" genetic profile featuring a mosaic of blue, red, orange, and black pigmentation against a pearlescent base, this Small variant is a masterclass in organic texture. In the "Answering Machine" era of specialized goldfish husbandry, the Shubunkin is prized for its extreme hardiness and its ability to provide a high-impact, multi-color presence in large indoor systems or outdoor aquatic architectures.
Unlike the compressed "fancy" varieties, the Shubunkin maintains a streamlined, single-tail body profile that allows for high-velocity maneuvering and superior metabolic resilience. This is a foundational specimen for those looking to introduce a robust, long-lived resident into biologically diverse cold-water setups.
Note: Images shown are stock images and not the actual fish you will receive.
Visualization Note: Some product imagery utilizes generative AI to provide a high-fidelity representation of a mature specimen’s architectural profile. These are not photos of the specific individual you will receive, as biological variance is a standard in high-end husbandry.
Care Level: Easy
Temperament: Peaceful
Variant Size: Small
Minimum Tank Size: 30 Gallons (Initial) / 75+ Gallons (Mature)
Diet: Omnivore
Reef Compatible: N/A (Freshwater)
Max Size: 10 to 12 Inches
Temperature: 65° to 75°F
dKH: 5 to 19
pH: 6.5 to 7.5
The Shubunkin Goldfish requires a stable freshwater environment with significant horizontal clearance to accommodate its athletic swimming mechanics:
Structural Layout: Minimalist layouts with smooth river stones and robust plants (Anubias or Java Fern) are recommended. Avoid delicate flora that may be compromised by the specimen's foraging behavior.
Swimming Lanes: Maintain open horizontal space; the Shubunkin’s aerodynamic profile is designed for high-speed cruising.
Filtration: High-capacity filtration is mandatory. As high-bioload residents, maintaining pristine water quality is the primary success factor for long-term vitality and immune function.
This is a social, high-energy species. They integrate best with other streamlined goldfish varieties such as Comets or Common Goldfish. They can also be housed with robust, cool-water species like Rosy Barbs or Weather Loaches. Avoid housing with slow-moving "fancy" varieties (like Ryukins or Orandas) that may be outcompeted for metabolic resources, or aggressive residents that may view the Shubunkin's flowing fins as a target.
Success with Carassius auratus hinges on a varied nutritional protocol. They are opportunistic foragers and should be fed twice daily with high-quality sinking or floating pellets. Supplement with blanched greens and frozen bloodworms to maintain peak chromatic saturation and digestive health. Regular 30–50% weekly water changes are the primary success factor for managing the bioload in closed systems.
We utilize specialized logistics for national Overnight Delivery to ensure livestock arrives in peak condition. Every order is packed using professional-grade insulation and climate-contingent heat or ice packs to maintain stable temperatures throughout the journey. This protocol is strictly designed to minimize transport stress and ensure a technical transfer from our facility to your tank with zero compromise on health or vitality.
