Here are Jay-Jay (all brown), Jimbo (white,brown,black), Pepe (black with white crest), and Chino (black and brown) eating their favorite foods: Parsley, celery and cucumbers. They are all males that live happily together.
Oh you can't feed guinea pigs celerly it is bad for them. They can't digest it properly or something. I read it in a guinea pig care book. "Also avoid long stalks of celery, which are impossible to digest..." page 33 "heath and nutrition"
