Your boyfrind gave you his brother's turtle that has a red ring around it's neck? Is the ring completely around the neck or just in spots? Is the red area open like a sore? Can you post a picture of the neck area? The redness could be due to a number of things--an infection or an abrasion, for example.
It would have been better not to put the turtle in with your turtle right away and rather quarantine the new turtle for several months in his own set-up so you wouldn't have the worry you have now about your turtle getting the redness.
How big are both turtles (shell lengths without the curves) and what size tank do you have them in?
Try to post a pic of the neck area with the redness...
