For Bolivian Rams to chase each other? Especially one doing all the chasing? Do females chase each other? I'm not sure which I have in my son's tank but their breeding areas look the same on both so I figure it's either 2 females or 2 males.
My Rams have always chased each other, it's just a simple matter of 'who's boss'. It is no doubt the male doing the chasing, and I'd be almost surprised if there was no chasing going on. Nothing to worry about
They're just letting each other know where they can/can't go.
It should settle down eventually, mine did it all the time and eventually seemed to get bored of it... And I had a female that chased the other female too.
