breeding?

I have three african cichlids (not sure what species, theres a few that look a lot alike)(the ones with spots on their anal fin) but I have a pale blue/white one that cleaned out a stump decoration thing, and is having little siezure things. then it tries to get a the darker gray/blue one to follow it in there. I don't see any eggs, but it won't let anything near the stump except the other cichlid. they are both about 4 inches.
