The Timeless Classic for Your Outdoor Oasis
Our Robust Standard Fin Koi 3-4 inch for sale represent the pinnacle of traditional pond aesthetics. Known for their sleek, powerful bodies and crisp color definition, these standard-fin varieties are the direct descendants of the world-renowned Japanese lineages. At this size, they are hardy, curious, and ready to be trained to hand-feed.
Why Choose Our Premium Standard Grade? At Fish R Us, we cull for quality so you don’t have to. Our 3-4″ specimens are selected for:
Body Shape: Strong, torpedo-shaped frames that allow for massive growth potential.
Pattern Definition: Clear “kiwa” (edges) between colors, whether you’re looking for a bold Kohaku or a metallic Ogon.
Vibrant Health: Every fish is conditioned in our facility to ensure they arrive at your door with a robust immune system.
Current Size: 3-4 Inches
Max Size: 24–36 Inches
Type: Standard Fin (Classic)
Water Parameters: pH 7.0–8.5; Temperature 32–85°F
Tip: Standard Fin Koi are aggressive eaters! To build a thick, healthy body and vibrant scales, use a combination of our Fish R Us Growth Pellets (high protein) and Fish R Us Spirulina Pellets (for color and digestion). These smaller koi benefit from being fed 2–3 times a day in small amounts to maximize their growth during the warm months.
