Here's a tip that I thought I should put out:

If you are getting another Guinea pig, or have had one and are introducing the new one to the older one, and you put them in the same(large) cage then before you do, do a huge clean through. Clean everything that might have a scent on it. Do not use lysol or any other cleaning products like that. try using vinger or bleach mixed with water. it is not harmful to Guinea Pigs and Guinea Pigs do not like the smell of vinegar and bleach so they don't smell their scent on it. Then you have no problems with fighting.
