Most rosy red minnows sold as feeders are young, stressed, and/or sick so it's usually not possible to sex them while at the store in a feeder tank. Once mature and healthy, a male is about 50% larger than a female of the same age. He has a fleshy bump on the top of his head and tubercles on his gills when ready to spawn (white spots on the gills). The mature female has an ovipositor (a little white tube sticking out of her vent through which eggs are laid) and a larger abdomen. In rare cases, a pet store may have some older minnows, and that information might allow you to find a male or female specifically.
