I have a 55 gal salt water and im new to this. I had some yellow tail damels, 2 clowns, a coral beauty and a yellow tang. Then i introduced a foxface who is larger than any of my others. At first things were ok but now my foxface is distressed and I'm wondering if i made a bad choice. My yellow tang seems to be intruding on the save where the foxface likes to hang and arms to be stressing the fox. Suggestions?
