Hello, I have 155 gallon tank with live rock and I have no coral as of right now. I currently have dog face puffer and emperor angel. I had a foxface but he and Emperor fought until one day I found Foxface deadening in tank . The foxface and emperor were in tank for about a year until they started to fight. My question is I would like to add fish but I'm a little reluctant to do so. What kind of fish can I add and how many ? Thanks
