I'm pretty sure you have all females, except 1 of the pearls is a male. Given that, I think you could add a male gold or opaline. You could also go with a female (or multiple) of either color. Just by adding 1 more, you'll probably notice a difference with the aggressive behavior being more spread.
BTW, all the opalines I have/had (includes males & females) are/were at least somewhat of a bully. Not sure why that color strain seems to be the meanest.
