i used to think they were catfish lol until i got one on a little carp boilie and saw it up close then i thought it was a malnourished carp until a friend told me it was a sucker lol. seeing schools of these things is a great sign right now, it means the fishing season has OFFICIALLY begun! i see groups of 15 or more of these cruising the bottom of the shallow mud flats in my local lake and that is natures hint telling me to bust out the pike gear and start fishing in that area
