Come to think of it, i did notice something like that happening in my tank when i added the tetras to an existing group of boraras, there was abit of chasing around for the first few days. After some time, the boraras eventually claim the back of the tank and the tetras claim the front, once both groups settled into their areas, then no more chasing.
I guess sometimes that could happen in a tank with different fishes, they need some time to establish a pecking order amongst all the fishes, then things will eventually settle down.
