Black Fathead Minnows (Pimephales promelas) also known as tuffies or blackhead minnows a variety of minnow used primarily as a feeder fish providing a healthy food source to feed other aquatic pets. We have both a small (0.5"to 1.5") minnow which is great as feeders and then a larger 1.5-2.5" minnow that is better as bait. Minnows are omnivores and mainly eat zooplankton and phytoplankton, but will eat all types of small dried and live food. Fathead minnows are fractional spawners and spawn throughout the spring and summer once the temperatures are about 65 degrees. Their high reproduction rate make them an excellent stocking choice as forge fish or bait for crappie, perch, bluegill or bass.
