It’s #Festivus, so you know what that means - time for an Airing of Grievances about a #GreatLakes Grinch!
Goldfish (Carassius auratus) - yes, the goldfish of home aquariums worldwide - have unfortunately been an invasive species in the #GreatLakes for decades #25DaysofFishmas

Quillbacks are deeper-bodied than most suckers, giving them a carp-like appearance. The genus name “Carpiodes” means “carplike” + the species name “cyprinus” refers to the generic name of the common carp, so together, Carpiodes cyprinus basically translates to:
“Carp carp” #25DaysofFishmas
