Just bought a silver last week around 7 inches. Took him home and he tried the pellets right away, but spit them out almost immediately. The next day I tried it again with the same exact outcome as the day before. The third day I got worried and went out to the LFS and bought him frozen dried krill. He took that in a heartbeat. Started feeding him that and fed my cichlids pellets and out of nowhere he takes them and eats a couple. So now I mix it up with a couple and krill and a some pellets. Seems like a pretty good diet to me as long as no feeder fish are involved.
