Hi everyone this is my first post here on saltwaterfish.com. I have my first two marine fish ever. I only planned on one but when my lfs tried to remove the one i picked they would not separate. I hate to breakup good things. They still get along perfectly in my tank. But ive come with a question. My male (smaller of the two) has a white spot between his 2nd and 3rd stripe. The owner of my lfs told me he was an abnormal. Is this bad or harmful in any way?
