Can Orfe and Goldfish Crossbreed? Identifying Mystery Fry

No Hybridization

Orfe (Leuciscus idus) and goldfish (Carassius auratus) are different genera, families even. They cannot produce viable offspring.

Orfe spawn readily but eggs/fry are usually eaten before noticed. Your orfe's "trimming down" was likely post-spawn weight loss.

They're hardy, colorful, and perfect for your pond.
