I'm guessing that these are adolescents? I've no experience with rams, but if they are anything like kribs, I'd figure that they just need time and space to get it right. They paired but weren't able to complete the process of raising fry, solidifying their bond and maturing him into a proper mate. I'd guess that he will eventually pair off again for another try. With 2 females I'd figure that he will eventually pick one and outcast the other. I'd give lots of hiding places and attempt to feed in a way that they don't fight for it. I see this type of activity in my tanks but most of the time reversed, with the female Kribs being very aggressive until the males are ready to pair up. (Mainly because my female fry grow quicker. I need to desperate them sooner but I'm still building that tank..heh) 6
Hopefully someone who breeds rams can help out more.
Of course, this could merely be aggressive behavior and nothing more, but what it sounds like is that he is ready to breed and the female is not. Give them some time. The fact that they paired once is a good sign. Also, I'm not sure if rams pair for life or if they will raise a harem. I only know Kribs, so that's all I can really say and it may very well be bad info, I don't know. good luck!
