Location: Upper Potomac River Tributary, Maryland
All species were photographed underwater, not caught. I realize that the picture quality might not be good enough for identification, but I thought that maybe I'd try.
Darters:
Tessellated or Greenside? My hunch is Tessellated. The known darters in this drainage are Rainbow, Fantail, Tessellated, and Greenside.
Cyprinidae:
Other...Northern Hog Sucker?
Here is a list of the cyprinids that could be in that stream:
Stoneroller Capostroma anomalum Red Shiner Cyprinella lutrensis Spotfin Shiner Cyprinella spiloptera Goldfish Cyprinus auratus Common Carp Cyprinus carpio Silverjaw minnow Ericymba buccata Cutlips minnow Exoglossum maxillingua Pearl Dace Margariscus margarita Bluehead Chub Nocomis leptocephalus River Chub Nocomis micropogon Bull Chub Nocomis raneyi Golden Shiner Notemigonus crysoleucas Comely Shiner Notropis amoenus Satinfin Shiner Cyprinella analostanus Emerald Shiner Notropis atherinoides Bridle Shiner Notropis bifrenatus Ironcolor Shiner Notropis chalybaeus Common Shiner Notropis cornutus Spottail Shiner Notropis hudsonius Swallowtail Shiner Notropis procne Rosyface Shiner Notropis rubellus Mimic Shiner Notropis volucellus Bluntnose Minnow Pimephales notatus Fathead Minnow Pimephales promelas Blacknose Dace Rhinichthys atratulus Longnose Dace Rhinichthys cataractae Creek Chub Semotilus atromaculatus Fallfish Semotilus corporalis
