Food that is liked by catfish & silvertail catfish are cornmeal balls & also nightcrawler worms or almost any kind of foul smelling bit wil most definitley reel in catfish.
Silver tipped catfish love meaty foods the best. Feeding them live bloodworms or nightcrawlers, depending on the catfish's size, will be relished. Small bits of cocktail shrimp are also a great treat for these fish.
Well first off it depends on how big the fish is. I would not buy feeder fish from certain stores because if you fish eats a sick fish it will die. I would stick with a pellet or flake food.
