Aggresive Guinea Pig Behavoir

Question
I have two young male guinea pigs, both are the same age, one a little smaller than the other. They are frequently chattering their teeth, biteing each other, and squealing in very high pitched squeals. We got them both at the same pet store a cupple days apart some time in the middle of june this year. They started fighting a cupple of weeks after we got them. I've tried giving them separate food dishes and everything. But they always seem to fight over where to sleep and which bowls to eat out of. The bigger one always chases the smaller one away from his food dish even though its not hungry or its eating from the other one. When the bigger one picks a place to sleep the other sleeps in the other house and the bigger has the nerve to chase him away from his separate house. If we want to pet them or pick them up they usually spring forward and bite us. its not a friendly nip either their bites can draw blood. Weve tried spending lots of quaality time with them, like brushing them and giving them extra carrots, but they don't seem like they are warming up with us. Their cage is 18 by 42 and its 27 inches high so they have plenty of room to run around and avoid each other but the usually don't. I need to know what I should do so that they will warm up to us and stop fighting I what them to have a happy and long life. thanks!

Answer
I know this is very frustrating but they will have to be separated, I have only had a handfull of males that have ever gotten along long-term together and most were either brothers or older pigs. Most males don't get along and the territorial issue is whats making them bite you, they are too involved in fighting and trying to protect themselves to be able to let their guard down to be friendly. Also I know how that goes with getting them from a pet store together, for some reason most guinea pigs will get along at pet stores together then once you get them home they start fighting, I think it is because they actually have something to fight over at home, lots of hiding spots good food and a nice cage, so they think that if they fight over everything eventually they will get separated and have just as much for each of them. Guinea pigs can injure each other by fighting so I would separate them as soon as possible, or you could place a metal, wood or grate divider in the middle of the cage and just add another water bottle and food dish. I have had females that even do this to me, some pigs just don't get along no matter how hard you try, males are really bad about not getting along, I have mostly given up about trying to stick males together except for brothers and tiny babies, most of the time it just doesn't work. If you separate them, or use a divider they should warm up to you, just let them cool down for a day and then try to handle them, first try handing them little treats like carrot or apple from your hand, usually the way to a pig's heart is through its stomach. They both probably have dominant personalities too, most of the time if males can be together they either have to have both ressesive personalities or one can be dominant, otherwise they just don't stop fighting for dominace of everything in the cage. Also pigs don't start getting along with in a day then they most likely never will, or at least not until they get old and lazy, then they won't want to fight. Sorry about the disappointing news, but there is not much you can do other than divide the cage of separate them. Let me know if you have any more questions.
