There seems to be lack of info re. the breeding of Sarcocheilichthys sinensis sinensis(Amur Sucker / Scarlet Carp / Chinese Lake Gudgeon). Literature found state that this fish has never been bred in captivity. This peaceful species is an unusual addition to any coldwater aquarium.I have introduced 6 specimens (approx 10cm) in my pond and was lucky enough to collect 24 young Amur Suckers this summer. Apart from Hornwart, the pond is occupied by freshwater mussels. I cannot really tell wheather the mussels played an important role in the breeding since the pond is a bit deep.
