Help with guinea pigs fighting

[car]

Hi looking some advise on my two guinea pigs behaviour.
I lost a guinea pig due to old age I left it a week then got a new guinea pig (fudge 18weeks) to keep my other guinea pig squeaky (1 1/2) company introduced them slowly for a week before putting them in the same cage they seemed to be getting along fine and had one fight after the first couple of days fudge drew blood from squeakys nose but they have got along for over a month with no other problems but the past week fudge seems to be chattering and making a rumbling noise whenever squeaky goes anywhere near him i have had to put in two bowls for food as he nudges squeaky out of the way and wont let him get any food today i noticed part of squeakys ear is missing i have attached some pictures (hopefully done it right) not sure on what to do with them should i seperate them or just keep a closer eye on them i have a two tier homemade cage and they have lost of room sure they are both male
thanks Carol

Once they draw blood you need to seperate.As one of them has had a bitten nose then an ear I we ould seperate them before any more damage is done.The older one could cause serious injury to the baby.
