Pond Boss Forums INTRO Questions & Observations Rehabbing Mr. H's small pond

I have some fish like that in the pond in my neighborhood.They can get up to 10 inches long, i am referring to theos picture.Kinda looks like some grass carp as well.But i dont think the mouth is right for a grass carp? I would like to know what they are and if i should put them in my LMB and BG pond??thanx
