Has it gotten violent at all?

If they are just displaying for each other and shaking, it could be pre-spawning behavior. It sounds like one is trying to impress the other. Sometimes fish will spread their fins and tail-slap each other, which could be pre-spawning behavior or establishing dominance. My severums and discus do this when fighting over food or territory, for instance.

If it's non-violent, I wouldn't worry about it. If the submissive fish is retreating because it's being attacked, you may have to separate them if it gets worse. I know that my male Krobia is very pushy and aggressive with the female when he's in a breeding mood, and occasionally she has to retreat to a flowerpot or piece of driftwood to catch a break from him. So sometimes even though it's a breeding behavior, it can still get a little pushy.
