The sea slug

I have three firefish in my tank. While in hindsight this was likely a bad choice, I had heard that they needed company, and I could afford three. Anyway, two of them paired up and are kind of bullying the third. He/she hides all day in the rocks, and gets chased if he/she comes out. Do I just need to move the third, or is there a less obvious solution that I'll like better?
