Fish will often take food into their mouth, spit it out, and repeat until the food softens up some. This is more prominent when the pellet size is a bit big for the fish to swallow and/or the food is unfamiliar.
I bet your BG and CC will take to it real soon. If your BG are taking, spitting, taking, spitting, & loosing it...your CC may be getting it as it falls.
