Identifying Baby Fish in a New Pond: Goldfish Fry vs. Stowaways

8 Baby Fish at 1 Month: Color Variations Explained

Pond started with 2 koi + 2 comets. Friend gave anacharis & lilies. Now 8 babies: 3 colored (orange, one with white stripe), 5 brown/black.

Origin

• Almost certainly from eggs on donated plants. Goldfish spawn on vegetation; eggs hitchhike.
• Goldfish fry are all brown/gray initially—camouflage. Color develops over months.
• Colored ones may be early-maturing goldfish or koi hybrids.
• Koi x goldfish hybrids are sterile; often lack full color.

What to Expect

• Brown fry will likely turn gold/orange over 3–12 months.
• If no color by 2–3 inches, they may stay wild-type (bronze).
• Not all goldfish turn "gold"—some remain olive/brown.

Enjoy the surprise! They're likely goldfish, not koi.
