Jake,
In addition to Bill's comments on Identification, I'd like to add that grass carp never hit lures, in my experience (although there is always a first time), and to my knowledge eat only vegetable matter, not BG. Even common carp do not normally eat BG nor hit lures although occcasionally that does happen. I'm wondering if someone slipped a buffalo (rough fish) in with your grass carp. What you describe is most unusual behavior for the grass carp we see in Texas.
