Two 22mth old sister gerbils started to fight. Help please!

We've had this pair of female gerbils for 22mths now living happily in a
glass tank. A couple of days ago they started to fight - seriously. In a
tight ball and drawing blood. We managed to separate them in time and they
have survived with no obvious permanent injuries. I have split the tank
diagonally to separate them.

Can we ever reintroduce them. I know that 2 gerbils that have drawn blood
never get together but these two have been together for all their lives.
Has anyone had any similar experience? What did you do?

Many thanks

Are they in heat? Use a screen to divide the cage. They may start
getting along which means you can put them together but you may have
to keep them apart from now on
