Golden orfe / ide

Leuciscus idus

An active golden pond fish with a barbel-free mouth.

Length and basis: Typical adult TL unknown
Reference temperature: Unknown
Captive lifespan: Unknown (no verified lifespan adopted)
pH: Unknown
Hardness: Unknown

Plan a large, oxygen-rich pond; inadequate space and low oxygen increase jumping risk.

Appearance and identification

Golden, natural and blue forms share one species. A short dorsal, single forked tail and barbel-free mouth are useful browsing cues; colour alone cannot confirm identity. Larger fish can eat small fish.

Same-species behaviour

Active swimmer; no sourced numerical group recommendation adopted.

Space requirements

Provide open swimming space and reliable oxygenation. A verified footprint, population context and minimum pond volume are not yet available.

Diet and feeding

Offer suitable pond food; natural foods include insects and other invertebrates, and larger fish take small fish.

Compatibility limits

Small fish can be prey; check species-specific medication sensitivity before treatment.

Aquarium environment

Planting can provide cover, while open swimming room and oxygenation remain essential.

Measurement notes and sources

Canal & River Trust lists 25–50 cm without a length basis or husbandry context; USGS separately lists 102 cm. Neither calibrates the sprite.
