So, I've recently added a few fish to my system and I'm getting some slight bullying from my six line. In the past, I've thrown him in my sump as a time out for a few weeks and re-introduced him with no signs of aggression successfully. Currently, my sump setup does not have baffles so there is a protein skimmer and return just sitting in an acrylic cube. Would a healthy fish have any issues steering clear of these for a week or two? My other option is a breeder box in the tank but I don't want him to jump out of it, and i feel the sump has more room for him to swim.
