I would not get one of the same size...I've always been told to get either a smaller one or larger one. If yours is already pretty big, get a smaller one since your larger one is probably already a female.
I had a smaller gold stripe and got a larger maroon (about 1 inch difference) and put them both in my larger tank at the same time and I was lucky since they seem to have paired up.
I'd be careful with adding any new maroon to your tank if your current one is already established...they can be very territorial even to other maroons! You might want to try changing the rock and stuff around a bit so it isn't so territorial with a new one.
Good luck! Hopefully you'll get lucky like I did and they will pair up.
