This kelberi has been on pellets for 2+ yrs. before I got her, so I don't think feeders are the answer but I can give silversides a try.
I despise feeding feeders at this point just because of a illness I got from the last time I did it. Not to mention I feed nothing but massivore and my bass have seen live food once. But if I have a fish that wont eat anything, I will give them a couple feeders just to entice them to eat a little bit. Seemed to work well in the past for me. That includes fish that have been on pellets. Just nerve racking waiting for them to adjust. But good luck with your bass. He/she is a beaut.
