Might be easier to transition from live to raw shrimp or tilapia. If you can get him on pellets though, that's probably best for the long term.Whenever I was breaking my fish off live, slivers of tilapia (cut to look like small fish) worked best. I didn't have much luck with silversides, and I'm not sure why. I feed all my fish shrimp and tilapia, just cut to different sizes for different fish, but if I could just throw a handful of pellets in at night, it would be a lot easier.
