LOL, you can't win for losing can ya mate?
How bad was the fighting? I always let my cichlids fight and settle things on their own. IMO, this is always an ongoing thing with cichlids, whether it be the dominate one making sure the subdominates remember who's the boss, the subdominate one grows and wants to test the old guy out, or they just might be bored or having a bad day or just po'd about something in general. The fighting usually never amounts to much.
Only you know how bad it is when they fight but unless you think there could be some major damage I would let them settle it on their own. Cichlids are very hardy and it takes a lot to kill them.
The reason I think it might be best to let them work it out is because IME, with a divider, my cichlids would try to jump over the top or try to break it down (and sometimes succeeded) and would then kill the other fish if they had bad intentions. The fact that they are both sulking and not flaring across the divider or charging it leads me to believe that they were just being normal cichlids and should be fine.
Like I said tho, this is only IME and I'm not there and all cichlids are different, so if you feel differently by all means keep the divider up.
