Severum aggresion?

[Severum-Breeder]

my breeding pair seem irratated at something they shake not like breeding but rather violently. theyll scoop rocks up and spit them out theyll bite and shake on some of the decor. theyve done this for a while but i figured it to be a breeding shake but they did it even after breeding and its been almost 2 weeks since their last batch of eggs

You just described every bit of normal behavior for most CA/SA cichlids. All these fish redectorate, they tail slap or fan to show dominance. Unless theyre hurting each other I wouldn't give it a second thought.
