Okay so a little less than a week ago I added a cherub angel/Atlantic pygmy angel to my 39 gallon bowfront. Compared to the mandarin, citron goby and firefish housed with it he swims around the tank like a madman and adds a lot of life to the tank. The problem is that he bothers my firefish to the point that I barely see it anymore because it hides out in the rockwork. That firefish is the first saltwater fish I got in the hobby so I really don't want to get rid of him. Will they eventually work themselves out or should I try a different pygmy angel?
