So long story short I have 3 Red Head or Shoulder Severums. One is always getting cased in my tank by the other two. So I'm thinking I could have a pair? Below are pictures of the two that do the chasing ... mind you the don't chase each other. I tried to get a photo of the one being chased but he or she wouldn't stay still.
Fish #1
Fish #2
Hope these two photos help answer my question.
