Ctenopharyngodon idella (VALENCIENNES, 1844)

Grass Carp

September 30th, 2014 — 12:57pm

Despite being a wholly unsuitable aquarium subject, C. idella is often traded as such, with an albino form having been developed specifically for the ornamental market.

Individuals which have outgrown their aquarium or pond should never be released into natural waters, either, since this species has proven capable of causing serious environmental damage under a wide range of climatic conditions.
