Came home from work today to see two of my Golden Zebra really greyed out and they appear to be squabbling. Tight close together and chasing each other in quite tight circles. Didn't appreciate actually how greyed out they can become !!! Do I need to be monitoring this or leave them to iron it out ??! I'm assuming it's a dominance issue here ? They are in a group of 5 and none of the other have greyed out or even seem particularly bothered as to what's going on.....

Many thanks
Jules
