If it will fit in his mouth, my jag will eat it! (if it squirms watch out!)
I feed him pellets, earth worms, meal worms (in other words leftover fishing bait), grasshoppers, crickets (theres plenty of them in the pasture right now), beetles, flies (its either throw them in the garbage or the fishtank cause I dont want them in the house anyway), and ocaisionaly feeder comets.
A varied diet makes for a healthy fish!
